Because the ridge is the site of focused volcanic activity, seawater circulates actively to cool the new crust. The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles). At a convergent boundary with at least one oceanic plate, an ocean trench, a chain of volcanoes develops and many earthquakes occur. Plates move apart at mid-ocean ridges where new seafloor forms. -Seafloor spreading and other tectonic activity processes are the result of mantle convection. A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. In contrast, the East Pacific Rise spreads fast, at rates of 6 to 16 centimeters (3 to 6 inches) per year. What kind of feedback loop is at work? Site Info, NOAA Ocean Exploration oceanic ridge, continuous submarine mountain chain extending approximately 80,000 km (50,000 miles) through all the world’s oceans.Individually, ocean ridges are the largest features in ocean basins.Collectively, the oceanic ridge system is the most prominent feature on Earth’s surface after the continents and the ocean basins themselves. *, Fresh Kills Landt in Staten Island was stated to be a temporary place to put garbage from metropolitan areas of New York City. none of the above, Technological methods used to prove that plate tectonics occur include: c. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. There are other parts of Staten Island the trash could go to instead Due to the fast spreading rates, there is no rift valley in the Pacific, just a smooth volcanic summit with a crack along the crest that is much smaller than the Atlantic rift valley. The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes. Adiabatic melting of the mantle, also known as decompression melting. subduction of the ocean floor take place in what boundary do 2 plates pull apart As plates move, they product mountains, volcanoes and valleys as well as mid-ocean ridges and deep-ocean trenches. Setting B is at a mid-ocean ridge (decompression melting) where reduction of pressure carries the rock at its temperature across the solidus. Melts are focused as they ascend through the upper mantle and lower crust and collect beneath the ridge axis in elongate melt lenses.

But it means that the ocean floor acts like a conveyor belt, slowly but steadily moving away from the mid-ocean ridge. What features of seafloor is described as the deepest areas of the ocean where subduction takes place? paral|Points 22006| User: used as evidence for continental drift The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth’s surface (Figure 4.5.

The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet). Found inside – Page 471As we have seen, continued submarine basalt volcanism that takes place at mid-ocean ridges formed at diverging oceanic plates. User: process that takes place at mid-ocean ridges Weegy: There are two processes, ridge-push and slab-pull. Seafloor spreading takes place at midocean ridges and produces basalt, the rock that makes up the oceanic crust. 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. 5.

Plate tectonics is now recognized as the surface manifestation of a greater process—circulation of the solid earth. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. Found inside – Page 274The Role of Fluids in Terrestrial and Extraterrestrial Processes Daniel Harlov, ... are transform faults, which occur along almost all mid-ocean ridges. Ocean trenches. About 90% of mid-ocean ridges are underwater, but there is a length through Iceland that is above sea level.

Thus the mid-ocean ridge is also known as a "spreading center" or a "divergent plate boundary." The plates spread apart at rates of 1 cm to 20 cm per year. As oceanic plates move apart, rock melts and wells up from tens of kilometers deep. Sea floor spreading the tectonic process that takes place along mid ocean ridges.
