Layers of the Earth and Plate Tectonics

Front

What are the three main layers of the Earth?

Back

The three main layers of the Earth are the crust, mantle, and core.

Front

What is the outermost layer of the Earth called?

Back

The outermost layer of the Earth is called the crust.

Front

What is the composition of the Earth's inner core?

Back

The inner core is composed primarily of solid iron and nickel.

Front

What is the layer between the crust and the inner core?

Back

The layer between the crust and the inner core is the mantle.

Front

What type of boundary occurs when two tectonic plates collide?

Back

A convergent boundary occurs when two tectonic plates collide.

Front

What is the layer of the Earth that is made of tectonic plates?

Back

The crust is the layer of the Earth that is made of tectonic plates.

Front

Which layer of the Earth has the highest temperatures?

Back

The inner core has the highest temperatures.

Front

What is the primary material that makes up the mantle?

Back

The mantle is primarily made up of silicate rocks.

Front

What is the process called when tectonic plates move apart?

Back

The process when tectonic plates move apart is called divergence.

Front

What is the significance of the lithosphere?

Back

The lithosphere is significant because it includes the crust and the uppermost part of the mantle, forming the rigid outer layer of the Earth.
