Plate Tectonics Review

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What happens when two tectonic plates collide?

Back

One plate often moves below the other, which can lead to volcanic activity.

Front

What is a volcanic island?

Back

An island formed by volcanic activity, often resulting from the rising magma at convergent plate boundaries.

Front

What evidence do trilobite fossils provide?

Back

They provide evidence of past plate tectonic movement, indicating that continents were once connected.

Front

What causes tectonic plates to move?

Back

Convection currents in the Earth's mantle drive the movement of tectonic plates.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often creating deep ocean trenches.

Front

What is a deep ocean trench?

Back

A deep, narrow depression in the ocean floor formed at convergent boundaries.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other, often causing earthquakes.

Front

What is a fault?

Back

A fracture in the Earth's crust along which movement has occurred.

Front

What is seafloor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.
