Front

What land formation occurs at a divergent continental/continental boundary?

Back

Rift valley.

Front

What is the process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle?

Back

Subduction.

Front

What type of boundary is the San Andreas Fault in California?

Back

Transform boundary.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other.

Front

What geological feature is formed at a convergent boundary?

Back

Mountain ranges, deep ocean trenches, or volcanic arcs.

Front

What is the theory of plate tectonics?

Back

The theory that the Earth's outer shell is divided into several plates that glide over the mantle.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another and sinks into the mantle.

Front

What type of boundary is associated with earthquakes?

Back

Transform boundaries.
