Yes, the Earth's landmasses are in constant motion due to plate tectonics. Plate tectonics is the theory that the Earth's lithosphere, which is the solid, outermost layer of the Earth, is divided into several tectonic plates. These plates are constantly moving, interacting with each other at their boundaries. The movement of the plates is driven by convection currents in the Earth's mantle, the layer of the Earth beneath the lithosphere.
Was Africa joined to South America in the past?
Yes, Africa and South America were once joined together as part of the supercontinent Gondwana. Gondwana was one of two supercontinents that existed during the late Paleozoic and early Mesozoic eras, Pangea being the other. Gondwana began to break up about 180 million years ago, and Africa and South America separated completely about 100 million years ago.
