Earth science: convection, natural hazards, continental drift

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 layer of earth changes because of the convection cycle?

• Crust

• Core

• Mantle

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

• hot = less dense

• hot = no change

• hot = more dense

What is the heat source for convection in the mantle?

• the Crust
• the Mantle
• the Core

When molten  material is cooled in the mantle it becomes

• more dense
• less dense

When molten  material is heated in the mantle the molecules

• expand (spread out)
• condense (shrink together) 
• stay the same
