Earth Science Vocab Review

This layer of Earth is the hottest and under the most pressure.

This man developed the theory of Sea Floor Spreading. What is his name?

This is the process where a denser plate sinks below a less dense plate and gets recycled.

When these two plates collide, tall mountains are created.

This is the force that causes the tectonic plates to move along the crust of Earth.

This type of boundary opens up the ocean floor and allows the creation of new rock.

When these two plates collide, volcanic islands and trenches are created.

This is the layer of the Earth found BETWEEN the crust and the mantle. (#4)

These waves cause the most damage on the surface.

What is the name of the scale used to measure the strength of earthquakes?

This man agreed with Wegener and completed the theory of Plate Tectonics. Who is he?

This is the name of the plates that carry land.

These waves CANNOT travel through liquids.

This is where, on the surface of the crust, you can clearly see the break in the rock.

Tectonic plates move how far each year?

This man was responsible for the theory of continental drift. What is his name?

This is the name of the plates that carry oceans.

The place deep under the surface of Earth where the energy for the earthquake starts.

These waves are the fastest traveling waves.

The scientific theory that says what is happening now will continue to happen in the future.
