Compare Sea Floor Spreading And The Formation Of Mid Ocean Ridges

Compare sea floor spreading with the formation of mid ocean ridges sea floor spreading is the process where two ocean plates move apart from each other.

Compare sea floor spreading and the formation of mid ocean ridges.

Mid ocean ridges are underwater mountain ranges that typically occur at the center of an area of sea floor spreading. At mid ocean ridges magma rises to the earth s surfaces and pushes older material away. Summarize the theory of pate tectonics. Compare sea floor spreading with the formation of mid ocean ridges.

The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed. The mid ocean ridge is the region where new oceanic crust is created. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. The process of sea floor spreading.

Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. The theory that explains the movement and changes of earth s crust. The spading of the ocean ridges are caused by the plate boundaries moving apart form each other in different directions. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.
