Plate Techtonics

Front

What are mid-oceanic ridges?

Back

Mid-oceanic ridges are underwater mountain ranges formed by divergent tectonic plates moving apart.

Front

What type of plate boundary is formed when two plates move away from each other?

Back

Divergent boundary.

Front

What geologic feature is likely to form when an oceanic plate slides under a continental plate?

Back

A mountain on the edge of the continental crust.

Front

What happens to the age of the crust as you move away from a hot spot?

Back

The crust gets older.

Front

What type of plate boundary occurs when two plates slide past each other?

Back

Transform boundary.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past one another horizontally.

Front

What is the result of a divergent boundary?

Back

The result is the formation of new crust as magma rises to the surface.

Front

What is a tectonic plate?

Back

A tectonic plate is a large slab of Earth's lithosphere that moves and interacts with other plates.

Front

What is subduction?

Back

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