WHAT CAUSES TECTONIC PLATES TO MOVE?
Tectonic plates are lying on top of the
mantle

WHAT CAUSES TECTONIC PLATES TO MOVE?
Movements in the mantle cause
tectonic plates to move

WHAT DO YOU THINK? THINK-PAIR-SHARE
Which one is heavier/more dense:
Hot things or cold things
Example: hot water vs cold water,
hot air vs cold air

CONVECTION
Convection—movement of particles caused by difference in temperature
Circulates moves in circular pattern

WHAT DO YOU THINK? THINK-PAIR-SHARE
Where is it hottest in earth’s layers?
Where is it coldest?

CONVECTION AND THE MANTLE
hot mantle rises
cool mantle sinks
1. heat from core heats up rocks in
mantle
mantle cools (more dense)
rock expands(less dense)
