Explain the difference between the outer core and the inner core.

• The outer core is liquid while the inner core is solid.

• Both the outer and inner cores are solid.

• Both the outer and inner cores are liquid.

• The outer core is solid while the inner core is liquid.

The four main layers of the Earth in order from the outermost to the innermost are:

• Crust

• Inner Core

• Outer Core

• Mantle

Draw and label a diagram of the layers of the Earth. Include crust, mantle, outer core, and inner core.

Why is the outer core liquid while the inner core is solid?

• Lower pressure in the outer core causes it to remain liquid

• Higher temperature in the inner core causes it to solidify

• Different chemical compositions of the inner and outer cores

• The outer core cools faster than the inner core
