How They Are Made
Fault lines
The MID-OCEAN RIGID is basically a huge underwater mountain which stretches about 49,700 miles underwater forming a giant s shape on the ocean floor, near the Mid Atlantic. It runs along the Atlantic, Indian, Arctic, and Pacific ocean. The rigid's can form mountains and the tops of the mountains can point out of the water and on to the surface which forms islands such as Hawaii. Rift valleys are also formed due to the volcano and magma located in the mantle and it forms rift valleys and these rift valleys can be as deep or deeper than a mile.
