Destructive:
80% of all volcanic activity happens on destructive margins.
Fold mountains:
Constructive: - volcanoes + earthquake
Oceanic crust moves together which makes sea floor spread/ ridges: mid Atlantic ridge: which makes Europe and America to move away from each other
Continental collision: - volcanoes + earthquake
is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of sub duction, whereby the sub duction zone is destroyed, mountains produced, and two continents sutured together.
E.g.: Andes, Himalayas
Transform/ conservative:
Fault line
Move same direction, at different speeds
Or in alternate directions
