What plate boundaries causes sea floor spreading?

Biology
1 answer:
Blababa [14]3 years ago
7 0

Answer: Seafloor spreading occurs at <u>divergent plate boundaries.</u> 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.
