The main force that shapes our planet's surface over long amounts of time is the movement of Earth's outer layer by the process of plate tectonics. 

The rigid outer layer of the Earth, called the lithosphere, is made of plates that fit together like a jigsaw puzzle. These plates are made of rock, but the rock is, in general, lightweight compared with the denser, fluid layer underneath. This allows the plates to "float" on top of the denser material. The fluid dense material is called asthenosphere and in this activity it is represented by the frosting. However, plates are not all the same. Plates made of continental crust are thicker but less dense than plates made of ocean crust, which are denser but thinner.  Movements deep within the Earth, which carry heat from the hot interior to the cooler surface, cause the plates to move very slowly on the surface, about 2 inches per year on average. There are several different hypotheses to explain exactly how these motions allow plates to move.

Interesting things happen at the edges of plates. At divergent plate boundaries, rift valleys and spreading ridges form as plates pull away from each other. At convergent plate boundaries, where plates are coming together, subduction zones form when an oceanic plate and a continental plate collide and mountains build when two continental plates collide. Large faults form when plates slide past each other making the Earth tremble with earthquakes.

Key Vocabulary:
1. divergent plate boundary – a plate boundary at which the plates are 
moving away from each other 

2. convergent plate boundary – a  plate boundary at which the plates are 
moving towards each other

Plate movement can affect the construction of the earth. I think this because in the plate tectonics lab we moved the graham crackers in different ways to represent different things. Like when we slid the plates against each other it simulated earthquakes. Also when we pushed them together they represented the making of mountains. Another thing that plates do is that every year they make the continents move about 2 inches. that is how tectonic plates affect the construction of the earth.

Plate Tectonics affects the construction of the earths surface by the plates moving together. When the plate tectonics move together it pushes the crust up and makes the crust vibrate and it eventually gets destroyed. When it gets destroyed it affects the earths construction and it can never get fixed. That’s how plate tectonics affects the construction of the earths surface.
Plate Tectonics affects the destruction of the earths surface because when the plates are moving together and its already destroyed it can destroy it even more. When they are moving together it destroys the earths construction so when its destroying it, it can destroy it even more.

Plate movement has a huge impact on Earth's surface. What it can do can deeply affect the Earth's surface, and us. Since we live on top of the plates, there movement can change our environment. This can have both a positive and negative affect on us.

The Earth's plates are what we live on. They make up a huge part of the construction of the Earth. They are what form our mountains, rift valleys, and lots of other things too. They make up landforms, and without them the Earth would be really different, because since the plates are below us, the way they move constructs the surface of the Earth. For example, if two continental plates collide, it can form a mountain. That mountain can affect people, animals and plants. Plate movement has a big impact on the way the Earth is constructed.

As much as plate movement can be helpful in the construction of the Earth's surface, it also causes destruction. For example, when plates slide past each other it causes earthquakes. Earthquakes can cause lots of damage. Buildings can fall, things can get destroyed, and trees can fall. They can also change landforms around us, impacting everything.

1. The plates affect the construction of the earth’s surface by creating mountains and other land forms. The plates make the land rise from the ocean. Without the plates, the whole earth would be flat! The plates shape the continents and the landforms on it.
Why is flat bad?
Most people would say it’s not, but without the plates to make land forms the world would be lame. This is true because due to the plate movements we have cool land forms like mountains [convergent plate boundaries] and valleys [divergent plate boundaries]. Without them this world wouldn’t be that cool. Basically, the surface is shaped by the plates.

2. The plate movement directly effects the destruction of the earth’s surface. I think this because of many things. Faults lines are where faults used to be. If a huge earthquake were to happen, the fault could be huge making a gaping hole in the earth’s surface.
Also, the plates could diverge and make a huge valley. The plates have the power to even sink the continents if it is possible. As you can see, the plates can do just about whatever they want to the earth’s surface.

There are three types of plate movements involved in the plate tectonics.
Divergent- plates move towards each other
Convergent- plates move away from each other and last
Transform- plates slide past each other
In conclusion divergent and convergent plate movements change the earth by destroying it's crust or creating new land crust.

             In some places, land is destroyed in subduction zones.  In others, new land is formed where mountains are created along a convergent plate boundary.  One of the places that this (the recreation of earth's crust) happens is along a mountain range under the Atlantic ocean, it is here that some of earth's crust is recreated.
             Having the different types of fault line could bring different outcomes.  Such as having mountains and valleys or trenches on the faults.  Having so much activity on the crust lines could and has shaped earth's crust in many different ways.  One specific place on earth where this happens is: Under the pacific ocean there is a fault line right in the middle.  There is a subduction zone there, the biggest in the world!

These tectonic plate movements can effect the construction of the earth in places like like Japan and Chile. The reason why is because all the places have natural disasters that have to do with tectonic plates that lead to bad construction. Like Japan and Chile have lots of earthquakes, caused by tectonic plates, which makes bad construction. So therefore where there are lot's of earthquakes there is bad construction.

The destruction on the earth also can happen because of the tectonic plates. Like Japan and Chile have earthquakes that occur because of tectonic plates moving. Chile has had a monster 11 earthquakes in the last 112 years. And Japan has had 10 which causes a lot of destruction caused by tectonic plates moving.

Volcanoes are formed when oceanic and continental plates collide.

Plate Tectonic affected the constuction of the earth's surface. All the plates fit together like a puzzle that formed the crust. This is called the lithosphere.The plates colide and shift creating mounatins to rest on the earths surface. The plates move slowly around on top of the denser material that lies beneth them.
The plates affect the desrution of earths suface by creating natural diasters. When plates move away from eachother, they create rift valleys and spreading ridges. This movement is called divergent plate bounadries. When plates move towards eachother, it is called convergent plate boundaries. When less dense but thicker continental plates colide with more dense but thinner oceanic pleats it causes moutains and sometimes volcanoes to form. This is called subdution zones.

Plate movement directly affects the construction of the Earth by creating stuff like volcanoes and mountains. It creates mountains when two continental plates collide. When they do, the dirt and rock gets pushed up and creates a mountain. Volcanoes are formed the same way as mountains, except they form over hot spots. The magma at the hot spot goes through the volcano, creating an eruption.

When I think of how plate movement affects the earth’s surface I think of convergent. That is when two plates are heading towards each other and are about to collide. Eventually the plates will collide creating a new feature such as mountains. When I think of this type of movement I think of the Himalayas. The biggest mountain range the Himalayas, were formed by the collision of the Indian and Eurasian plates. That is my example of how plate movement affects the construction of the earth.


When I think of how plate movement affects the destruction of the earths surface I think of subduction zone. That is when the oceanic plate goes under the land mass. When it goes under the land mass it goes through heat and pressure what results into the oceanic plate turning into magma. When I think of this type of plate movement I think of the ring of fire. I think of that because this is happening along the boundaries of the ring or fire. That is my example of how plate movement affects the destruction of the earths surface.

Plate movement affects the earths construction by causing mountains and valleys to form. As the plates move away from each other, a large space in the ground forms creating a valley. As plates push towards each other the ground move up creating mountains. These two types of plate boundaries are called divergent (pulling away from each other), and convergent.

Plate movement destroys the earth’s surface. When plates move apart, the ground splits apart. Whatever is near the edge will fall into the hole. When plates slide past each other an earthquake will occur. When this happens the earth shakes violently.

Plate movement effects the construction of the earths surface when convergent plates meet. When they come together they form a subduction zone. A subduction zone is when a oceanic plate and a continental plate collide and form a mountain, which is construction.

Plate movement directly affects the construction of earth’s surface. When two plates move away from each other they are called divergent plate boundaries. When this happens the earth gets spread out. Divergent plate boundaries are the cause of valleys. In our lab, when we moved the two graham crackers away from each other the frosting (that was underneath the crackers) got smoother and flatter and more spread out. Another way the plates construct the earth is when two plates get pushed into each other this is called convergent plate bounderies.When this happens it creates mountains. In the lab when we pushed the two crackers together the frosting rose up just like the mountains.

One plate movement that directly effects the earth is convergent plate boundaries. This is when tectonic plates are coming together and subduction areas arrange when an oceanic plate and a continental plate come together and mountains are made when two continental plates collide into each other. When this happens, there are usually volcanoes and mountains near subduction sites because subduction creates volcanoes and mountains. This happens a lot around the world, for example; this is happening around Hawaii and that’s why there are so many active and non-active volcanoes there.

Another plate movement that effects the earth is divergent plate boundary. This is where two plates move away from each other. This movement in the earth’s surface causes rift valleys and spreading ridges. For example, this is happening to the Mid-Atlantic Ridge is a classic example of this type of plate boundary. The Ridge is a high area compared to the surrounding seafloor because of the force from the oceanic plates going away from each other leaving a ridge in the ocean.

Some of the tectonic plate’s movement builds things on the earth. For instance sometimes they build mountains. Other times they build mountain ranges or volcanoes. They create these things by colliding into each other. Mountains don’t become mountains over night it takes thousands of years for mountains or volcanoes to form.
Some of the tectonic plate’s movement destroys things on earth. For example when tsunamis occur it is because of underwater earthquakes or underwater eruptions. Earth quakes happen because two plates rub against each other and then suddenly stop that is when earth quakes happen. Underwater earthquakes are just like above water earthquakes.

Without tectonic plates, we would not have all these landforms.

Plate movement directly affects the destruction of Earth’s surface because earthquakes occur when the tectonic plates slide past each other a little bit where they overlap.

Plate movement can do a number of things to the Earth’s crust. For example, it can construct it, with mountains, or destruct it, with volcanoes--the lava spews all over the plants and animals. An example of the tectonic plates construction, usually on a convergent plate boundary, are mountains or volcanoes. Another way is creating mountain chains. One more way is creating valleys or a rift.

An example of destruction is a volcano when it is active. Another example of destruction that plate tectonics cause are earthquakes, because they destroy buildings and roads.

One example of plate tectonics directly building up the surface of the earth would be when convergent boundaries create mountain ranges. One reason they are so obviously directly altering the earth’s surface is simply found in the graham crackers when the two graham crackers collided to make a “mountain range”. For example: one place that the convergent boundaries are most obvious is the Himalayan mountain rage, where the Eurasian plate and the Indian plate converge. That was just one way that the plates create evident activity on the crust of the earth and there are many other ways that the tectonic plates construct the surface of are earth.


One way that the tectonic plates destroy the surface of the earth is for example: earthquakes. Earthquakes destroys land around it and alters the earth’s surface when two plates slide next to each other along the fault lines making the earth tremble. When the earth trembles it causes earthquakes near the fault line. One example of this is the great San Francisco fire and quake. This famous earthquake was started when the North American plate slides along the pacific plate causing a great disturbance. When this occurs it destroys the buildings and sometimes landforms.

That means that two plates pull away from each other. When that happens rift valleys and spreading ridges form.

Two main forces are responsible the construction of the earth’s crust. The first force is called a divergent boundary, when a plate pulls away from on another. This type of boundary is directly responsible for the construction of the earths crust. On this boundary the magma that is pushed though the gap in the plates cools to form an extension of the continent and therefore is constructing the earth’s crust. The second feature is the volcano, which is really just a feature of a convergent boundary. These volcanoes allow magma to rise to the surface and cool as lava on the surface, which can extend continents and form new ones.

The destruction of the earth surface is when a dense tectonic plate slides under a less dense plate and melts back in to the mantle, as is caused by a converging plate boundary. The convergent boundary destroys plates little by little while forming mountains ranges, volcanoes and divergent boundaries in the process. This is what I find so interesting about the earth- it keeps a balance between creation and destruction.

One way plate movement can effect the construction of earth’s surface is when a plate slides below another plate and forms a volcano. After a volcano erupts, the lava hardens and creates new land. At divergent boundaries, new land can be made in between the two diverging plates. Also, Mountains can be constructed when two plates collide.
Tectonic plates can effect the destruction of earth’s surface by producing earthquakes, which can destroy many things. Another feature that destroys things are volcanoes, even though they can also make new land. Convergent boundaries can also construct and destruct the surface of the earth. They can build new mountains but when a mountain is formed, the flatter land that used to be there is destructed.

The tectonic movement can construct the world by making mountains and uprooting stones and gems. These are called continental plates. Mountains created by such plates also start a fresh water sources. Rain slides down a mountain and forms the tract of a river. Fresh water rivers are required to start a civilization. Oceanic plates, which are constantly in motion, form waves in the ocean.
Tectonic plates destruct the earth by causing structure shaking earthquakes, destructive tsunamis, and violent volcano eruptions. These disasters either bury, flood, or destroy everything around it. They are a danger to humans and animals. Therefore, tectonic plates can be resourceful creating life and civilizations, as well as destroying everything.

This can prevent against minor tornadoes and earthquakes but it can’t against major ones. This is important because it can wipe out most of a city.
Weather can affect the way we live because of transportation delay, money loss for support or repair and a lot of other things. weather also affects the way we live because it can change the temperature. i know this because when my windows open on a clear night its decent but when it's rainy it's really cold.
The characteristics of a hurricane are that they can be very violent and cause thousands of dollars worth of repair. They also get weaker when they hit land because water fuels it. This is important because on land it’s most powerful when it just hits land so people on the coast should get reinforced windows. They may cost a little bit but its will be worth it. And if you live in a place with few hurricanes then just get reinforced glass.

Plates on the earth are giant floating landmasses of rock.
They play a role in creating earth. The plates move apart and magma gushes up in the crack. The magma cools into rock creating land.
Plates also destroy land by colliding. This breaks them and causes earthquakes. Subduction (when a plate slides under another plate) this also melts plates back to magma.

Plate moving directly affects the construction of the Earth’s surface. This is because when the plates crash together it creates mountains. Also at a subduction zone volcanos sometimes occur when a continental plate and oceanic plate collide. That is how plate moving directly affects the construction of the Earth’s surface.

Plate movement directly affects the destruction of the Earth’s surface. An example of this is that at divergent plate boundaries rift valleys occur. Another example is that sometimes plates break apart creating earthquakes that can result in chasms and canyons. That is how plate movement directly affects the destruction of the Earth’s surface.
