What Is The Action Force Responsible For Seafloor Spreading? The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones, rather than magma pressure, although there is typically significant magma activity at spreading ridges. What are the 4 steps of seafloor spreading? Magma comes out of the rift valley. Magma cools
What Is The Economic Importance Of Continental Shelf? The distribution of the continental shelf is significant since it is the nursery ground for living resources and an important source of minerals and offshore petroleum. Why are continental shelves important to the ocean ecosystem? The continental shelf is one of the most productive parts of the
What Is The Slowest Spreading Ocean? The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end. Which ocean is spreading the fastest? Some of our recent research involves hydrothermal and structural investigations along Earth’s fastest
What Is The Process By Which The Ocean Floor Sinks Beneath A Deep Ocean Trench And Back Into The Mantle? Subduction is the process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle. What is the process that continually adds new crust to the ocean floor along both sides
What Do The Stripes In The Paper Represent In Split And Separate? The stripes on the strips stand for the magnetic stripes located on the ocean floor, which indicates the reversal of the Earth’s poles. The stripes need to be identical on both sides of the strip because they represent stripes of a magnetic field
What Do The Slits Represent? The side slits stand for where subduction has occurred and the ocean floor has sunk in. Also, the space under the paper stands for the oceanic crust of the Earth. What do the side cuts stand for what does the space under the paper stand for? What does the space
What Describes The Ocean Floor? The ocean floor is literally the floor of the ocean. It is the bottom of the ocean when you dive. … According to Scientific American, the ocean floor has been mapped to a resolution of 5 kilometers as of 2014. This means that anything larger than 5 kilometers (3.1 miles)
What Does The Pattern Of Magnetic Stripes On The Seafloor Indicate? When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. … This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading.
What Feature Of The Ocean Floor Does The Center Slit Stand For? What feature of the ocean floor does the center slit stand for? The center slit stands for the passage where the molten material can enter the Mid-Ocean Ridge, formed by the converging of plates. What feature of the ocean floor does the center
