Ways plates move

Question 1

3 ways that plates move

Answer 1

Convection currents
Slab pull
Ridge push

Question 2

Convection currents

Answer 2

In the mantle
Movement of particles from an area of high temp. to an area of low
Circular action from outer core to crust to outer core again
Drives movement of plates

Question 3

Slab pull

Answer 3

Only at destructive plates
Subducting plate pulls the rest of the plate with it
Frictional resistance causes earthquakes

OCCURS AT DESTRUCTIVE BOUNDARIES

Question 4

Ridge Push// Gravitational sliding

Answer 4

Upwelling of new magma pushes the middle of the ocean ridge
Slopes away from the ridge
Gravitational sliding from there
Also some frictional resistance causing earthquakes

OCCURS AT CONSTRUCTIVE BOUNDARIES
