Answer:
Both explain how the movement of the Earth's crust occurs.
Answer:
Option (C)
Explanation:
The mid-oceanic ridges are the submarine mountains that are formed in a divergent plate boundary. In this region, the oceanic crust gradually rises due to the movement of the magma towards the surface. This movement of magma upward is due to the formation of convection current in the mantle, where these currents are generated because of the heat energy provided from the interior of the earth.
These are the region, where the temperature is extremely high and the rocks are in the form of liquid (magma) and hot rocks are less denser than the cold rocks, so they move upward. This motion of magma upward and erupting on the seafloor leads to the uprising of the oceanic crust.
Thus, the correct answer is option (C).
Earth is basically from matter, all the matter around the Universe came together to form Earth, the only way for Earth to grow much bigger is if there was an unlimited supply of matter, there isn't and therefore Earth cannot get much bigger than it is now.
