This is when two plates are moving towards each other.
When an oceanic plate meets a continental plate the denser oceanic plate is forced down underneath into the mantle and destroyed. This often creates volcanoes and ocean trenches.
E.g The Pacific plate being forced under the Eurasian plate along the east coast of Japan.
Both plates are made from continental crust and move together.
Neither plate is forced down so the plates are forced upwards and folded.
It creates fold mountains
E.g. The Eurasian and Indian plates colliding to form the Himalayas.
Two plates moving away from each other.
Magma rises to form the gap and cools to create a new crust.
E.g. The Eurasian plate and the North American plate are moving apart at the Mid-Atlantic Ridge.
Two plates moving past each other in opposite directions or in the same direction but at different speeds.
E.g. The pacific plate moving past the North American plate on the west coast of the US like the San Andreas fault.
