Mantle Convection

Where do convection cycles happen?

• core

• mantle

• crust

Which material is more dense?

• solid

• liquid

• gas

Convection cycles move in the mantle. How does this affect the crust?

• crust has no motion

• crust moves in random direction

• crust moves in same direction convection cycle moves

What is magma made of?

• solid rock

• melted rock

• small pieces of sediment

Density has to do with what two things?

• Material and Volume

• Mass and Volume

• Mass and Density

• Material and Density

Which state of matter is least dense?

• Solid

• Liquid

• Gas

What layer of earth changes because of the convection cycle?

• Crust

• Core

• Mantle

If magma increases in temperature (get hot) what will happen?

• It moves down (sinks)

• It moves up (rises)

If magma decreases in temperature (cooler) what will happen to the magma?

• It will move down (sink)

• It will rise up (float)

How does density relate with viscosity?

• more dense, higher the viscosity

• less dense, higher the viscosity
