Amplify- Plate Motion Post Assessment Review

Front

What is the Earth's outer layer made of underneath the soil and ocean?

Back

Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

Front

What happens at the boundary where two tectonic plates are moving toward each other?

Back

Two plates are pushing against each other, causing the edges to bend upward.

Front

How did similar rock formations in Brazil and South Africa end up far apart?

Back

The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.

Front

What do patterns of volcanic activity and earthquakes on a map indicate?

Back

Volcanic activity and earthquakes happened in similar areas.

Front

Why is Africa closer to Europe now than it was in the past?

Back

The plates slowly moved toward each other as one plate went under the other plate into soft, solid rock over millions of years.

Front

What is a tectonic plate?

Back

A tectonic plate is a large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.

Front

What is the process called when one tectonic plate moves under another?

Back

Subduction.

Front

What geological features can form at convergent plate boundaries?

Back

Mountains, earthquakes, and volcanic activity.

Front

What is the theory of plate tectonics?

Back

The theory that the Earth's lithosphere is divided into tectonic plates that move over the asthenosphere.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.
