How do continents drift?
The Earth is made up of Tectonic Plates, these are large sections of land (Continental Plates) or ocean (Oceanic Plates). The Mantle (magma beneath the Earth's crust) is heated from the core of the Earth, where it is hottest, causing a convection current, this is when a fluid (magma in this case) is heated unevenly and the hot fluid rises, causing the cooler fluid to sink in its place (forming a circular current of heating, rising, cooling and sinking.)This current effectively drags the Tectonic Plates along in differenbt directions to each other, causing them to move apart or together, sometimes even alongside each other.
What is the force that causes plates to move sideways?
Convection. It consists of heated magma rising, then cooling, sinking, and reheating constantly in the mantle.
