Mantle
People breathe in oxygen. Which spheres are interacting?
Biosphere and atmosphere
What happens in the mantle that makes it flow/move?

The layer of gases surrounding earth.
Atmosphere
What is the thick molten liquid that makes up the mantle called?
Magma
A volcanic eruption sends ash and gases into the sky. Which spheres are interacting?

A tsunami floods land, washes away soil, and kills marine life. Which three spheres are interacting?
Hydrosphere, geosphere, and biosphere
Order the Earth's layers from hottest to coolest.
Inner Core, Outer Core, Mantle, Crust
This sphere includes rocks, sand, and mountains.
Geosphere
What is the difference between the inner and outer core?
One is liquid (outer) and one is solid (inner)
What is a system?
A group of parts that work together as a whole
Explain how convection currents work.
Hot magma rises to the top of the mantle, cools down, and sinks back to the bottom
