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.
Mid ocean ridges are places where "tectonic plates meet at divergent boundaries". These are areas of the oceans where underwater mountain ranges formed because of tectonic plates exist.
<u>EXPLANATION:</u>
The "mid ocean ridges" of the various oceans connect and form the mid oceanic range system which is considered to be the "longest mountain range" of the worldwith a length of 60,000 kilometers.
The mountain ranges are formed when the ocean floors get uplifted because of the convection currents.
This in turn leads to the tectonic plates meeting at divergent boundaries.
Landscapes have economic value because the owners of the land or the area have many visitors coming and going and they can put up shops etc to get money
