TCA 3/4 Earth's Changes and Plate Tectonics Review

Front

What technology helped Wegener's discoveries about the ocean floor?

Back

Electronic magnetometers and seismometers.

Front

How do tectonic plates cause earthquakes?

Back

Earthquakes occur when tectonic plates slide past each other.

Front

What are hot spots in relation to volcanic activity?

Back

Hot spots are areas where tectonic plates are stationary, allowing magma to rise.

Front

What is a deep underwater trough created by subduction at a convergent boundary called?

Back

Ocean Trench.

Front

What is the difference between oceanic and continental crust?

Back

Continental crust is thicker than oceanic crust.

Front

What is plate tectonics?

Back

The theory that explains the movement of Earth's plates and how they interact.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates collide.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move apart.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other.

Front

What is subduction?

Back

The process where one tectonic plate moves under another plate.
