New cards
The earths crust is broken up into...
pieces called plates
2
New cards
Why does the crust move?
Because of movements deep inside the earth called convection currents
3
New cards
What creates convection currents
Heat rising and falling inside the mantle
4
New cards
Plate Boundaries
Where two plates meet
5
New cards
Constructive/Divergent Plate Boundary
The two plates push away from each other
6
New cards
Destructive/Convergent Plate Boundary
Two plates move towards each other and one is forced to go under the other plate
7
New cards
Subduction zone
Caused at destructive plate boundaries where the denser plate goes under the other plate.
8
New cards
Collision/Convergent Plate Boundary
Where two plates move towards each other creating fold mountains.
9
New cards
Conservative/Transform Plate Boundary
Two plates sliding past each other in opposite directions or at different speeds.Friction is usually generated being released as an earthquake.
