Running along the top of this chain of mountains is a deep crack, called a rift valley ... At the East Pacific rise, which is pushing a plate into the west coast of South America, the rate ...

In this type of fault, the block of rock above the fault plane, known as the hanging wall, moves downward relative to the block below, called the footwall. Normal faults are typically found at ...

At divergent boundaries, plates move away from each other and form mid-ocean ridges or major rift zones, and at strike-slip boundaries plates slide past each other. But none of these plate ...

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.
