Plate Tectonics

Front

What is a Divergent Boundary?

Back

A plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What causes the movement of tectonic plates?

Back

The movement of tectonic plates is primarily caused by convection currents in the Asthenosphere.

Front

Which of the following is not a geologic feature: rift valley, earthquake, deep ocean trenches, mountains?

Back

Earthquake is not a geologic feature; it is a seismic event.

Front

What geologic feature is commonly found at a convergent boundary between two continental crusts?

Back

Mountains are commonly formed at convergent boundaries between two continental crusts.

Front

Why are earthquakes common in California and Japan?

Back

Both areas are on the boundary of active plates, and the motion of these plates causes earthquakes.

Front

What is a Convergent Boundary?

Back

A plate boundary where two tectonic plates move towards each other, often leading to subduction or mountain formation.

Front

What is a Transform Boundary?

Back

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

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What are convection currents?

Back

Convection currents are the circular movements of molten rock in the mantle that drive the movement of tectonic plates.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often characterized by steep walls.
