Answer:
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks. ... This rock (basalt) becomes a new part of Earth's crust.
In case you are doing the geography test the answer is:
