Layers of the Earth

The outermost solid layer of the Earth is called the

• mantle
• outer core
• inner core
• crust

This layer of the Earth is found between the core and the crust.

• mantle
• outer core
• inner core
• crust

The layer that lies beneath the mantle and surrounds the inner core. 

• mantle
• outer core
• inner core
• crust

Is a layer of weak, 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

What are the two kinds of crust that the Earth has?

• Oceanic and Crustatious Crust
• Oceanic and Continental Crust
• Optic and Continental Crust

This layer is completely liquid

• crust
• inner core
• mantle
• outer core

The circular pattern of heating, rising, cooling, sinking of magma in the mantle causing tectonic plates to move.

• Plate Tectonics
• Convection Currents
• Pangaea
• Subduction

Which best describes the asthenosphere?

• molten metal
• dense, solid metal ball
• solid that flows
• dry land and ocean floor

Convection currents occur in the mantle. Which statement best describes the motion of convection currents?

• Warmer matter rises and is less dense
• Cooler matter rises and is less dense
• Warmer matter rises and is more dense
• Cooler matter rises and is more dense
