Why are oceanic ridges elevated?

Oceanic ridges are elevated as new magma cools and becomes more dense. The newly created lithosphere at ridges is cold and therefore occupies less volume and is more dense than hotter rocks. … The density of the underlying mantle decreases, increasing its pressure, and therefore becomes part of the lithosphere.

What is a underwater ridge?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the 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.

What is the difference between a spur and a ridge?

Sometimes, two ridges come together at a point called a bifurcation. Ridge endings and bifurcations are known as minutiae.
