no they found ocean ridges sonar maps alone found deep-sea trenches
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
Mid-ocean ridges transfer energy from the mantle/asthenosphere/lithosphere to the surface. The energy is from the deep Earth.
most roundworms live in the small intestine of the host but some move through the host body till they get back to the small intestine sure they live in people's bodies but they also live in deep bodies of salt water and fresh water lakes plus don't forget the soil....
The deep *vertical* lines in your fingernails are genetic. If you have *horizontal* ridges in your nails, you should see a doctor.
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Horizontal ridges along the bridge of the nose.
the deep ocean basin consist of the deepest part of the ocean . :)
Deep ocean ridges, ocean trenches, mountain ranges, volcanoes, faultlines
