How many continental plates are there?
7
Which plate is heavy and dense?
Oceanic plate
Can the continental plate to be destroyed?
No only the oceanic plate can
How thick is the continental plate?
35km
How thick is the oceanic plate?
7km
Is the continental plate lighter than the oceanic plate?
Yes a lot
What word would you use to describe the continental plate?
In destructive
What are convection currents?
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
What is a constructive plate margin
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
What is a destructive plate margin
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
What is the other type of destructive plate margin
The two continental plates collide as they are the same weight they just push up forming a fold
What is a conservative plate margin
Two plates move past each other in two different directions or in the same direction at two different speeds the friction causes earthquakes
