Q

What are convection currents?

A

The currents in the magma. The hot lava rises and as it gets further away from the core it calls. This causes it to move the plate above

17
Q

What is a constructive plate margin

A

At a constructive plate margin and New Cross is formed to plate margins are moving apart magma is forcing its way to the surface both plates are continental

18
Q

What is a destructive plate margin

A

Two different plates (oceanic and Continental) are moving towards each other the oceanic plate is heavier so it goes under there is major friction between the two plates causing earthquake

19
Q

What is the other type of destructive plate margin

A

The two continental plates collide as they are the same weight they just push up forming a fold

20
Q

What is a conservative plate margin

A

Two plates move past each other in two different directions or in the same direction at two different speeds the friction causes earthquakes
