Sea Floor Spreading Occurs At Mid Ocean Ridges

2 molten material erupts inside the central valley of mid ocean ridges.

Sea floor spreading occurs at mid ocean ridges.

For instance the atlantic ocean is believed to be expanding because of its few trenches. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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 the rate of seafloor spreading determines the morphology of the crest of the mid ocean ridge and its. Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.

2 the farther from a mid ocean ridge a rock sample is take the younger the rocks is. Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them. The total capacity of the world s ocean basins decreases during times of active sea floor spreading. Subduction and sea floor spreading are processes that could alter the size and form of the ocean.

Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. The farther from a mid ocean ridge a rock sample is taken the the rock is. Usually these submarine mountain ranges have a valley running on their spine which is known as a rift and is about a mile in depth. The speed of spreading affects the shape of a ridge slower spreading rates result in steep.

This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Molten material erups the central valley of mid ocean ridges. A chain of underwater mountains along which sea floor spreading occurs is a. As the plates separate molten rock rises to the seafloor producing enormous volcanic eruptions of basalt.

Mid ocean ridges occur along divergent plate boundaries where new ocean floor is created as the earth s tectonic plates spread apart. 3 the pattern of magnetic stripes in rocks on either side of a mid ocean ridge is the same.
