GEOLOGY

Detailed explanation-1: -The mid-oceanic ridge is the place where two oceanic plates diverge, at the point where rising convection currents within the earth’s mantle spread sideways, forcing the plates apart and creating a rift, through which molten basalt comes to the surface along fissure eruptions and through volcanoes.

Detailed explanation-2: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

Detailed explanation-3: -As tectonic plates move away from one another at mid-ocean ridges, molten rock from the mantle may well up and harden as it contacts the frigid sea, forming new oceanic crust at the bottom of the rift valley.

Detailed explanation-4: -Two processes, ridge-push and slab pull, are thought to be responsible for spreading at mid-ocean ridges. Ridge push refers to the gravitation sliding of the ocean plate that is raised above the hotter asthenosphere, thus creating a body force causing sliding of the plate downslope.

Detailed explanation-5: -The mid-ocean ridge consists of thousands of individual volcanoes or volcanic ridge segments which periodically erupt.
