Front

Where do convection cycles happen?

Back

mantle

Front

Which material is more dense? Options: solid, liquid, gas

Back

solid

Front

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

Back

crust moves in same direction convection cycle moves

Front

What is magma made of? Options: solid rock, melted rock, small pieces of sediment

Back

melted rock

Front

Density has to do with what two things?

Back

Mass and Volume

Front

Which state of matter is least dense? Solid, Liquid, Gas

Back

Gas

Front

What layer of earth changes because of the convection cycle?

Back

Crust

Front

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

Back

It moves up (rises)

Front

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

Back

It will move down (sink)

Front

Why does hot mantle rise (go/move up)?

Back

hot = less dense
