Unit 5: Plate Tectonics Post-Assessment

Front

What is subduction?

Back

Subduction is the process in which two tectonic plates move toward each other, and one plate sinks beneath the other.

Front

What type of plate boundary forms folded mountains?

Back

Convergent boundary.

Front

What happens at a divergent boundary?

Back

Tectonic plates move away from each other.

Front

What geological event is best demonstrated by a model of a transform plate boundary?

Back

An earthquake.

Front

What does the theory of Plate Tectonics state?

Back

It states that Earth's crust and upper mantle are broken into sections that are in constant, slow motion.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What is the result of tectonic plates colliding?

Back

The result can be the formation of mountains, earthquakes, or volcanic activity.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together.
