Detailed explanation-1: -Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.
Detailed explanation-2: -He argued that the continents had once formed a singular supercontinent that he called Pangea, which means “all lands.” Over millions of years Pangea broke into several fragments, which began moving away from each other, slowly drifting to their current positions on Earth’s surface.
Detailed explanation-3: -In 1912, German scientist Alfred Wegener proposed a theory he called continental drift. According to Wegener’s theory, Earth’s continents once formed a single, giant landmass, which he called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.
