What goes on under the sea? Our oceans are so deep that the bottom of the ocean is a very mysterious place. We still don’t know a lot about what lies below the ocean’s surface. We do know, however, that the ocean floor is not flat. That’s because there are mid-ocean ridges that make the sea floor uneven!
What is a Mid Ocean Ridge?
A mid ocean ridge is basically a submerged mountain range. Imagine a connected series of mountains, but underwater! Mid ocean ridges form a ridge system across the Earth’s oceans. The entire mid ocean ridge system is a total of 49,700 miles long! This is the longest mountain range on the planet, even longer than mountain ranges on the ground! These ridges can also reach as high as 3,000 feet above the seafloor.
The Forces at Play
- Mid-Atlantic Ridge in the Atlantic Ocean
- Southwest Indian Ridge in the Atlantic and Indian Oceans
- Explorer Ridge in the Pacific Ocean
- East Pacific Rise in the Pacific Ocean
- Pacific-Antarctic Ridge in the Pacific Ocean
