Final answer:
Continents move due to plate tectonics, which explains how the Earth's lithosphere is divided into plates that interact and move. Plate boundaries are the regions where plates meet and their movement is responsible for the movement of continents.
Step-by-step explanation:
The movement of continents is known as plate tectonics. The theory of plate tectonics explains how the Earth's lithosphere (the rigid outer layer of the Earth) is divided into several large and small plates that move and interact with each other. These plates can contain entire continents, and their movement is driven by convection currents in the Earth's mantle. When two continental masses are moving towards each other, they collide and can create mountain ranges, such as the Alps formed by the African and Eurasian plates.
Plate tectonics is the scientific explanation for why continents move. It involves the movement and interaction of several large and small plates that make up the Earth's lithosphere. By understanding plate tectonics, scientists have been able to explain the movement of continents as well as other geological phenomena such as earthquakes and volcanic activity.
Plate boundaries are the regions where two plates meet. There are three types of plate boundaries: divergent boundaries (where plates move apart), convergent boundaries (where plates collide), and transform boundaries (where plates slide past each other). The movement of these plates at the boundaries is responsible for the movement of continents over long periods of time.
