Plate Tectonics Flashcards
(8 cards)
1
Q
Constructive plate
A
Moves away from each other, the magma from the earth flows up and dries to form new land immediately
2
Q
Destructive Plate
A
When an oceanic plate moves towards a continental plate, and subducts under it. The heat and pressure of the magma then melt the oceanic plate. This can form a trench.
3
Q
Conservative Plate
A
When two plates slide past each other. If the plates get stuck they can cause an earthquake.
4
Q
Collision Plate
A
When two continental plates slide toward each other. Can form mountains/hills.
5

Eurasian and North American
6
Q

A
The South American and nazca plate.
7
Q
