Mid-ocean ridge Hess discovered a system of mountain ranges on the seafloor separated by valleys, which he called the Mid-ocean ridge

A long narrow depression called a rift valley forms in between peaks along the mid ocean ridge.

the boundary where two plates collide is called a Convergent plate boundary

When a thick and buoyant continental plate meets a thin and dense oceanic plate, the denser dives beneath the continent in a process.

The boundary between two plates that are moving apart is called a Divergent plate boundary

This type of boundary where plates slide horizontally past each other in opposite direction called a Transform plate boundary

Is the sudden movement or vibration of the ground that occurs when rocks slip and slide along enormous cracks in Earth’s crust fault.

Is a crack in Earth’s crust along which rock has moves.

This sudden releases of strain energy as rock moves along a fault.

The point of origin for an earthquake.

The point on Earth’s surfaces directly above the focus.
