Multiple Choice

What is the top layer of the Earth's surface called?

• Mantle

• Innercore

• Outercore

• Crust

Crust

The crust is the outermost layer of the Earth!

Multiple Choice

Earth's inner core is

• a layer of hot rock

• a solid ball of iron and nickel

• a layer of liquid iron and nickel

• a layer of rock that forms Earth's outer skin

Inner Core

The inner core is solid iron and nickel due to the extreme pressure!

Multiple Choice

Which part of the Earth's core is liquid

• inner core

• outer core

Outer Core

The outer core is liquid iron and nickel due to the extreme heat!

Multiple Choice

What layer has plasticity and has convection currents that move the tectonic plates?

• lithosphere

• inner core

• asthenosphere

• outer core

Asthenosphere

This layer has plasticity (solid but flows) and contains the convection currents that move the tectonic plates in the lithosphere!

Multiple Choice

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

• Inner Core

• Lithosphere
• Outer Core

Lithosphere

This layer is where the tectonic plates are located!
