Why is sea floor spreading like a conveyor belt.

Farther from the midoceanic. It has to do with plate tectonics. They envisaged a conveyor belt model where new ocean crust formed at the ridge is imprinted with the prevailing magnetic field at the time and moves outwards as it gets older. It is like a conveyor belt because the two plates are pushing apart from each other like a conveyor belt divergence.

S concept of sea floor spreading at mid ocean ridges. New ocean floor forms along cracks in the ocean crust as molten material erupts from the mantle spreading out and pushing older rocks to the sides of the crack. New magma is being brought up from below the crust to continuously fill the crack. There s a plate boundary under the middle of the ocean and the two plates are moving away from each other.

In sea floor spreading the sea floor spreads apart along both sides of a mid ocean ridge as new crust is added. Explain how ocean floor rocks and sediments provided evidence of seafloor spreading it has deep trenches and high ridges. This new ocean floor is continually added by the process of sea floor spreading it continuously spread away from the ridges in a conveyor belt like motion. In sea floor spreading the sea floor spreads apart along both sides of a mid ocean ridge as new crust is added.

Reversals of the field led to the symmetrical pattern of stripes. So if you took samples from the sea floor the further from this boundary you are the older the rock is. Why is the hypothesis of seafloor spreading like a conveyor belt.
