Choose the two reasons why the inside of the Earth is still very hot

• Leftover heat from gravity collisions that formed Earth

• Incoming solar radiation from the Sun

Where do convection cycles happen?

• core

• Outer Core

• Inner Core

Earth's MANTLE is solid, but flows.

• True

• False

The liquid layer of the Earth's core. Very dense. Made of heavy metals.

• Outer Core

• Inner Core

An extremely dense sphere of solid iron and nickel at the center of Earth.

• Outer Core

• Inner Core

Solid, putty-like layer made up of the upper mantle. It's the physical layer below the lithosphere.
