HideShow resource information
What happens at a destructive plate boundary?
Oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes. Magma rises up through cracks and erupts onto the surface.

What happens at a constructive plate boundary?
The plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.
2 of 5
What happens at a conservative plate boundary?
Where plates slide past each other in opposite directions, or in the same direction but at different speeds.
3 of 5
What happens at a collision plate boundary?
Two plates come together and the material gets forced upwards creating fold mountains
