Movement of mantle 6th
- 1. MOVEMENT OF MANTLE Copy things down that are black 24L
- 2. WHAT CAUSES TECTONIC PLATES TO MOVE? Tectonic plates are lying on top of the mantle
- 3. WHAT CAUSES TECTONIC PLATES TO MOVE? Movements in the mantle cause tectonic plates to move
- 4. WHAT CAUSES TECTONIC PLATES TO MOVE?
- 5. 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
- 6. WHAT DO YOU THINK? THINK-PAIR-SHARE
- 7. CONVECTION Convectionmovement of particles caused by difference in temperature Circulates moves in circular pattern
- 8. WHAT DO YOU THINK? THINK-PAIR-SHARE Where is it hottest in earths layers? Where is it coldest?
- 9. 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)
- 10. CONVECTION AND THE MANTLE 1. heat from core heats up rocks in mantle 2. rock expands(less dense) 3. hot mantle rises 4. mantle cools (more dense) 5. cool mantle sinks
- 11. CONVECTION AND THE MANTLE Convection of mantle causes tectonic plates to move
