It has to do with plate tectonics.
Why is sea floor spreading like a conveyor belt.
So if you took samples from the sea floor the further from this boundary you are the older the rock is.
Explain how ocean floor rocks and sediments provided evidence of seafloor spreading it has deep trenches and high ridges.
It is like a conveyor belt because the two plates are pushing apart from each other like a conveyor belt divergence.
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.
Fonts 17 2 questions describe the topography of the seafloor.
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.
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.
In sea floor spreading the sea floor spreads apart along both sides of a mid ocean ridge as new crust is added.
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 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 along with them.
There s a plate boundary under the middle of the ocean and the two plates are moving away from each other.
