Earth's Layers Review

This is a layer of soft mantle that is made of rock that flows slowly. Tectonic plates move on top of this layer.

• Inner Core

• Asthensophere

• Lithosphere

• Outer Core

This is the outermost, rigid layer of the Earth, made up of two parts, is divided into pieces call tectonic plates.

• Inner Core
• Asthensophere
• Lithosphere
• Outer Core

The driving force of the tectonic plates are convection currents in the mantle. In which sub-layer can these be found?

• Lithosphere

• Mesosphere

• Asthenosphere

• Inner Mantle
