Earth's plates are...

• constantly moving and changing the earth

• Never moves

• Moves seldom and very fast

• Moves when it feels like it

Which layer of Earth is the thinnest? 

• Crust

• Mantle

• Inner Core

• Outer Core

Based on the information in the table, what can you conclude about the density of the Earth’s layers?

• The density increases in layers that are closer to the core of the Earth.

• The density of the layers increases as the temperature decreases.

• The density of the layers decreases as the pressure increases.

• The density increases in layers that are closer to the surface of the Earth

A force caused the continents to drift apart over time. Once scientists figured out what that force was, the theory of plate tectonics was born! The image above shows what Geologists think the Earth looked like millions of years ago. What name was given to this land mass.

• Plate Tectonics

• Oceana

• Pangea

• North America
