A repeated volcanic activity will create a volcano. where continental plates meet, the plate collides and the ground is folded and forced upwards to create mountain ranges. A earthquake can also take place because the land is moving it cause friction which can build up pressure and cause a jolt. 2 of 3 CONSRUCTIVE PLATE BOUNDARY This when two plate boundary are moving away from each other. This will then leave a gap in the boundaries The molten rock rises from the magma and fill the gap This creates new crust. Volcanoes can also form here, along the edges of the plate boundary, due to the rising magma. These volcanoes are called Shield volcanoes At this plate boundary a earthquake can also happen as there is movement of plates. 3 of 3
