Earth's Layers ESE

If you traveled from the center of Earth to the surface, the pressure would...

• increase
• decrease
• stay the same
• unsure

What is the outer core composed of?

• Basalt
• Granite
• Solid Metals
• Molten (liquid) Metals

What is the correct order (starting from the surface) of Earth's layers?

• crust, outer core, inner core, mantle
• mantle, outer core, inner core, crust
• crust, mantle, outer core, inner core
• outer core, inner core, crust, mantle

This layer of Earth is solid Iron and Nickel

• Outer Core
• Mantle
• Inner Core
• Crust

The lithosphere is made up of which two layers?

• Upper and Lower Mantle
• Upper Mantle and Crust
• Core and Mantle
• Crust and Uppermost Mantle

Why is the inner core solid?

• its unknown
• what it's made of
• the pressure
• it is colder than the outer core

A dense ball of solid iron and nickel.

• crust
• inner core
• mantle 
• outer core

How have scientists been able to study Earth's mantle?

• In some places, Earth's crust thins enough to see mantle.

• Earth's surface heat warms the crust turning it into mantle.

• Cooling crust material becomes mantle over time.

• In some places, mantle rock pushes to Earth's surface.

What evidence exists that proves that Earth has layers?

• They can be seen from special locations on the Earth

• observations of earthquakes and buildings swaying

• seismic data from earthquakes on the other side of the Earth

• tsunami data from other countries and the impact on the land

• rock samples from deep layers

Which layer is MOST dense?

• Mantle
• Crust
• Outer Core
• Inner Core
