What is meant by oceanic ridges?
An oceanic ridge is any elongate elevation of the deep seafloor that has steep slopes and irregular topography. Oceanic ridges are the topographic expression of linear or curvilinear zones along which the Earth’s oceanic crust is created or modified.
What is an example of a oceanic ridge?
Mid-ocean ridges form where two tectonic plates are pulling apart, also called seafloor spreading. The Mid-Atlantic Ridge, which is spreading one to two inches a year, along with the East Pacific Rise, which is spreading two to six inches a year, are two examples of very long mid-ocean ridges.
What is the other term of oceanic ridge?
A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of ~ 2,600 meters (8,500 ft) and rises about two kilometers above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary.
What is the meaning of ridge in science?
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side.
How is an oceanic ridge formed?
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 oceanic ridges and oceanic rises?
Ridges And Rises So, what’s the difference between a ridge and a rise? It has to do with how fast they are spreading apart. Ridges are spreading apart more slowly, and thus have steep slopes and higher elevations; Rises are spreading quickly, so have gentle slopes and are lower in elevation.
What is the meaning of mid sea?
Midsea meaning A point out at sea, away from the shore. noun.
What ridge means?
A ridge is a line that rises above what it is attached to. From the Old English hrycg, meaning “back of the man or beast” or “the top or crest” of something (combined, the senses mean “backbone”), ridge is often used for the beam that joins the parts of a sloping roof.
What is ridge in geography?
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side. Ridges are usually termed hills or mountains as well, depending on size.
