Unit 2 Plate Motion Test Review

Front

What is the evidence that continents are moving?

Back

Fossil records, GPS data, and rock type comparison are evidence of continental movement.

Front

Which is NOT a piece of evidence we have that the continents are moving?

Back

Visual observation of plate motion.

Front

What best describes Earth's mantle?

Back

The soft, solid rock on which the plates move.

Front

What is the definition of a 'plate' in geology?

Back

One of the large sections of hard, solid rock that make up Earth's outer layer.

Front

Which plate boundary typically causes the deepest earthquakes?

Back

Convergent boundaries.

Front

What causes plate motion?

Back

Plate motion is caused by convection currents in the mantle, not by earthquakes.

Front

What are the three types of plate boundaries?

Back

Convergent, divergent, and transform boundaries.

Front

What happens at a convergent boundary?

Back

Plates move towards each other, often causing mountains or deep ocean trenches.

Front

What happens at a divergent boundary?

Back

Plates move apart, creating new crust as magma rises to the surface.

Front

What happens at a transform boundary?

Back

Plates slide past each other, which can cause earthquakes.
