Plate Tectonics

Ali Fielder

What are plate tectonics?

Plate tectonics are parts of Earth, that are in constant motion. The motion is unnoticed, most of the time. The rub, pull, and push against each other, mean while creating

land formations.

What are the results of plate tectonics?

The results of plate tectonics is earthquakes.

Continental drift?

The theory of Continental Drift explains that the continents were once joined in a super continent, Pangea. The scientist that came up with this theory said that the continents move slightly over many years. Later proof of this theory came to our sights.

What are Plate Boundary Movements?

Divergent Boundary Movement- Divergent boundaries pull apart from each other. They are found under the ocean floor.

Convergent Boundary Movement- Convergent boundaries push together. They are found close to the surface of Earth.

Transform Boundary Movement- Transform boundaries rub against each other. They break off points in the rock formations of Earth.

What land formations do the plate boundaries cause?

Divergent- Sea floor spreading, land is destroyed, and new land is formed.

Convergent-Mountains, volcanoes, and deep-ocean trenches.

Transform- Earthquakes, fault lines, and oceanic fracture zones.

This is a mountain formation...the convergent boundaries push against each other. They can create mountains and volcanoes.

The picture above shows, when the continental crust pushes against each other, the space fills with magma. The mountains are formed, leaving a beautiful land formation.

As the picture above says, transform boundaries form earthquakes. It is an accurate diagram of how the two tectonic plates rub against each other, chipping some crust off. The subtle motion can be catastrophic. Many people die in earthquakes, and many others lose there homes. Keep in mind not all earthquakes are this destructive. Some can just shake your town a bit, without much damage at all.

All Together Now!

So, in conclusion, plate tectonics are huge slabs of rock found in earth's crust and upper mantle. They are in constant motion. They move in different ways, each creating a new land form. The transform boundaries rub, the convergent push, and the divergent pull.
