a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading. An example is the Mid-Atlantic Ridge. They are a result of SeafloorSpreading.
Mid-ocean ridges are a line of volcanic mountains under the oceans between the continents. As the oceanic plates are being pulled apart by the processes of plate tectonics, magma is formed from decompression melting in the mantle, and rises upward to fill in the gap that is created. Because this material solidifies and is still hot, it is buoyant and rises higher than the surrounding seafloor, creating the ridges. As it is pulled away from the spreading point by plate tectonics, it gradually cools, making it less buoyant; it gradually drops in elevation.

The mid-ocean ridge is the Earth's longest continuous mountain range, approximately 55-65 thousand kilometers long and bilaterally divided by a valley called a rift. The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge. Therefore, the ridge is composed of basalt and gabbro, and is among the most recent of geologic age crustal rock.

Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
One of the midocean ridges is, but others are in other oceans, seas, and bays.

friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridgegravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge
Thermophiles, they live at the deep sea smokers and require heat to carry out their biological functions instead of sunlight.

Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older

MidOcean Partners was created in 2003.
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.

it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
Thermophiles, they live at the deep sea smokers and require heat to carry out their biological functions instead of sunlight.
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
