Geography of Ocean Basins
Mid-Oceanic Ridge
By: Angela Garcia, Mark Frary & Jordan Ferguson
Abyssal Plains
New ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
Almost 71% of the planet's surface is submerged beneath water.
An Abyssal Plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
Known as "The wound in the Earth's Crust"
Our ocean floors of nearly every ocean are spreading wider and wider, by 3 ft (1m) every decade.
The Mid-Oceanic Ridge form the largest continuous geological network on the planet's surface.
