Question 14

What happens when continental crust clashes with continental crust?

Answer 14

We get fold mountains! E.g the Himalayas!

Question 15

What kind of plates are there? And in what ways do they collide?

Answer 15

Oceanic & oceanic
Continental &Continental
Oceanic & continental

Question 16

What happens when oceanic crust meets continental crust?

Answer 16

The oceanic crust is forced into the mantle where it melts and is recycled into the mantle this called a subduction zone

Question 17

What happens where plates separate?

Answer 17

Where two plates pull apart magma comes to the surface to fill gap the this is a mid-ocean ridge

Question 18

What happens when plates slide past each other?

Answer 18

We can often see a line on the Earth surface called a fault line E.G San Andreas fault line and earthquakes
