Earth's Layers Pt:2

Which layer of Earth is characterized by rock that is plastic, or soft enough to flow?

• Asthenosphere

• Lithosphere

• Crust

• Inner core

The driving force of the tectonic plates are convection currents, where can these be found?

• Inner Core

• Outer Core

• Mantle

• Crust

The outermost solid layer(1st layer) of the Earth is called the

• crust

• mantle

• inner core

• outer core

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

• Asthenosphere

• Lithosphere

• outer core

• inner core

Select the types of crust.

• Continental

• Fire

• Oceanic

• Volcanic

This type of crust overlies the ocean basins.

• Continental

• Oceanic

• Lithosphere

What is the reason that outer core is made of liquid materials?

• Because it is made of water.

• Because of heat from inner core

• Due to volcanic activities.

• Iron is always in liquid form.
