Tag Archives: how does mantle convection cause seafloor spreading?

The mantle is a layered part of the earth, which is located just beneath the crustal layer of the earth. The Earth’s crustal surface (lithosphere) rides atop the asthenosphere. The asthenosphere is the upper layer of the Earth’s mantle, in which there is relatively low resistance to plastic flow and convection is thought to occur. While the lower part of the mantle is very hot and molten. Mantle convection means the movement […]
