In sea floor spreading the sea floor spreads apart along both sides of a mid ocean ridge as new crust is added.
Why is sea floor spreading like a conveyor belt.
It has to do with plate tectonics.
As a result the ocean floors move like conveyor belts carrying the continents along with them.
Fonts 17 2 questions describe the topography of the seafloor.
New magma is being brought up from below the crust to continuously fill the crack.
As a result the ocean floors move like conveyor belts carrying the continents.
At ocean ridges are the longest mountain chains on earth s surface.
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.
In sea floor spreading the sea floor spreads apart along both sides of a mid ocean ridge as new crust is added.
S concept of sea floor spreading at mid ocean ridges.
Reversals of the field led to the symmetrical pattern of stripes.
Why is the hypothesis of seafloor spreading like a conveyor belt.
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.
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.
So if you took samples from the sea floor the further from this boundary you are the older the rock is.
