As the overlying plate lifts up, it also forms mountain ... that eventually build up into island arcs like Japan. At divergent boundaries in the oceans, magma from deep in the Earth's mantle ...

divergent, and transform boundaries. Explain why each of these boundaries has the particular observable phenomena the students have seen. 14. Have the students turn in their two annotated plate ...

St. Helens. Most of the subducting plate continues into the mantle, perhaps to reappear much later at a distant divergent boundary.

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

This is called a constructive or divergent plate boundary. These are usually found under oceans. As the plate moves apart, magma rises to the surface and cools, forming shallow-sided volcanoes.
