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.
Sea floor spreading occurs at mid ocean ridges.
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.
The main geographical feature formed by the process of seafloor spreading are mid ocean ridges.
Molten material erups the central valley of mid ocean ridges.
Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
2 molten material erupts inside the central valley of mid ocean ridges.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
2 the farther from a mid ocean ridge a rock sample is take the younger the rocks is.
For instance the atlantic ocean is believed to be expanding because of its few trenches.
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.
As the plates separate molten rock rises to the seafloor producing enormous volcanic eruptions of basalt.
The farther from a mid ocean ridge a rock sample is taken the the rock is.
The total capacity of the world s ocean basins decreases during times of active sea floor spreading.
A chain of underwater mountains along which sea floor spreading occurs is a.
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.
3 sea floor spreading occurs at mid ocean ridges.
3 the pattern of magnetic stripes in rocks on either side of a mid ocean ridge is the same.
Mid ocean ridges occur along divergent plate boundaries where new ocean floor is created as the earth s tectonic plates spread apart.
