divergent+plate+boundary

DIVERGENT BOUNDARY: is the boundary where to plates move away from each other.

WHAT HAPPENS: While the plates are moving away from each other magma begins to rise. once the magma reaches the surfaces it cools it forms a new oceanic lithosphere. This new rock is warm and light. It sits above the rest of the seafloor because its is less dense.

WHAT IT FORMS: This rock forms undersea mountain ranges also known as //mid-ocean ridge.// In the center of the mid-ocean ridge is //rift valley//. Rift Valley is: a narrow valley that forms where the plates separate. most divergent boundaries: ocean floor
