The process of sea-floor spreading created the lithosphere under the Atlantic Ocean. As North America and South America moved away from Europe and Africa, the resulting crack was filled by mantle material, which cooled and formed new lithosphere. The process continues today. Molten mantle materials continually rise to fill the cracks formed as the plates move slowly apart from each other. This process creates an underwater mountain chain, known as a mid-ocean ridge, along the zone of newly forming lithosphere.

A Mid-ocean ridge.
This is known as a Mid-Ocean-Ridge.

This is known as a tsunami.
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.

New oceanic crust is created at the mid-ocean ridges.
Its called a Tsunami, Japan just had one and was devastated!
A sea wave created when a seafloor slips after an underwater earthquake is called a tsunami. Tsunamis can travel across the ocean, carrying a large amount of energy and causing significant damage when they reach the coast. They are characterized by their long wavelengths and high speed.
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
