Plate Tectonics STAAR Review

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move apart from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate slides under another, often leading to the melting of the oceanic crust and the formation of volcanic activity.

Front

What geological features are formed at divergent boundaries?

Back

Geological features such as mid-ocean ridges and rift valleys are formed at divergent boundaries.

Front

What type of tectonic plate boundary is associated with earthquakes?

Back

Transform boundaries are associated with earthquakes as plates slide past each other.

Front

What is the Great Rift Valley an example of?

Back

The Great Rift Valley is an example of a divergent boundary where tectonic plates are moving apart.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates collide, which can lead to mountain building, earthquakes, and volcanic activity.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once part of a single landmass.

Front

What is the Mid-Ocean Ridge?

Back

The Mid-Ocean Ridge is a continuous mountain range formed by plate tectonics, where new oceanic crust is created at divergent boundaries.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing friction and earthquakes.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.
