Unit 9 Earth's Systems

What are the layers of Earth starting with the surface and going down to the center of the Earth?

• inner core, outer core, mantel, crust

• surface, magma, center

• crust, inner core, outer core, mantle

• crust, mantle, outer core, inner core

The mantle is hot, dense and flows very slowly; this causes the plates that make up the crust to:

• heat up and then cool down.

• move, which causes earthquakes.

• not move, which causes earthquakes.

• cool down and then heat up.
