The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics, and is initially formed as a result of changes in the convection currents which seek the least resistant point to the surface. 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.

What is the definition of mid ocean ridges?

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.

What are the crustal features of the land that are formed by plate tectonics?

Crustal features created by plate tectonics include mountains (e.g. Himalayas), trenches (e.g. Mariana trench), volcanoes (see the Ring of Fire), ocean ridges (Mid-Atlantic Ridge) and rift zones (regions lateral to a volcano that lava flows from).


How is crust created at the oceanic ridge?

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.
