Amplify Plate Motion - Final test

Front

What happens at divergent plate boundaries?

Back

Plates move apart, and new material from underneath fills the gap.

Front

What is a fossil?

Back

A fossil can be bones, hair, petrified wood, or stone imprints of animals.

Front

What type of rock is found in the outer layer under the ocean?

Back

Hard solid rock, specifically basalt rock.

Front

What occurs at convergent plate boundaries?

Back

Plates move towards each other.

Front

What is the outer layer of the Earth made of?

Back

The outer layer is made of hard, solid rock.

Front

What is the significance of GPS data in studying plate motion?

Back

GPS data helps geologists track the movement of tectonic plates.

Front

What is the process called when soft, solid rock rises and hardens at divergent boundaries?

Back

This process is called magma solidification.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and made mostly of basalt, while continental crust is thicker and made mostly of granite.

Front

What is the role of tectonic plates in earthquakes?

Back

Earthquakes occur when tectonic plates slip past each other or collide.

Front

What is the main cause of plate tectonics?

Back

The movement of molten rock in the Earth's mantle.
