Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
An underwater mountain chain that formed by sea-floor spreading is called a?
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
How did Harry Hess contribute to science?
Harry Hess's discovery was important because it helped explain the theory of continental drift. His discovery, that on the sea floor magma pushes up which causes the plate tectonics to move which carries the continents with it, explains better reasoning to the theory. It also helped the scienctist to explain how the sea floor spreading is happening.
Explain how scientist tink most magma is formed?
Magma is formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantel rock.
How do constructive forces help the earth?
They could help in creating new lithospheric (crust) plates. As in the case of divergent boundary, where new ocean floor is produced and expanded (sea-floor spreading).
New crust forms on the ocean floor due to what process?
Plate tectonics.
Which geologic process forms new crust on the ocean floor?
seafloor speading
The process of continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.?
sea floor spreading
New crust forms?
New crust forms at spreading zones like the Mid-Atlantic ridge in the middle of the Atlantic Ocean. They occur because of ocean floor spreading.
Where is the youngest ocean floor in the mid-Atlantic ridge?
Down the middle! The mid Atlantic ridge is a divergent plate margin along which new crust is constantly being produced.
The youngest rocks on the ocean floor are located?
The youngest part of the ocean floor is found at conservative plate boundaries where oceanic crust is pulled apart and magma rises from the mantle to form new oceanic crust.
What process adds new crust to the ocean floor?
Volcanic eruptions are one process that adds new material to crust. Lava from the volcanoes eventually cool, forming new land. Sea floor spreading also adds new material to the crust.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
When was the first concrete evidence found to support the theory that new ocean crust formed at vents in the ocean floor?
1977!
What is the Process that forms new ocean floor?
Extrusive igneous rock- Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the ocean to be pulled apart. This lava cools to form new ocean floor. Hope it helps.
What is the process that creates new ocean crust to form molten rock?
Sea Floor Spreading
