Amplify Plate Motion Final Test

Front

What is plate tectonics?

Back

The theory that explains the movement of Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere beneath.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

Front

What is a landform?

Back

A natural feature on the surface of the Earth, such as mountains, valleys, plateaus, and hills.

Front

What is the outer layer of the Earth made of?

Back

The outer layer, or crust, is primarily made of hard, solid rock.

Front

What is a cross section?

Back

A cut or slice through an object that shows its internal structure.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

What is the process of subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle, often causing earthquakes and volcanic activity.

Front

What is a fault line?

Back

A fracture or zone of fractures between two blocks of rock, which can lead to earthquakes.

Front

What is an earthquake?

Back

A sudden shaking of the ground caused by the movement of tectonic plates.

Front

What is a volcano?

Back

An opening in the Earth's crust through which molten lava, ash, and gases are expelled.
