11 materials in the mantle move via connection currents. which of the following explains how convection current is generated?
Answer (1)
A convection current in the mantle is generated when heat from the Earth's core heats the lower mantle materials, causing them to become less dense and rise. As these materials reach the cooler upper mantle, they lose heat, become denser, and sink back down. This continuous cycle of rising warm material and sinking cool material creates a circular flow called a convection current, which causes the mantle’s materials to move and drives the movement of tectonic plates on the Earth's surface.
