The two tectonic plates meet at point one. One is moving under the other, shown by the two arrows on the top pointing towards each other. The denser plate (left side) is subducted. This means the denser plate begins to go under the less dense plate. The lithosphere (crust/tectonic plate) is mainly solid rock. As it begins to go into the mantle it will begin to heat up as the mantle is hotter than the surface. The solid surface becomes a molten rock, known as magma. It melts as it goes down.
The correct answer is: Alfred Wegener. Alfred Wegener (1880-1930) was a German polar researcher, meteorologist and geophysicist, and a first person who suggested that the continents were once a supercontinent called Pangaea, but slowly drifted apart. While he was still alive, Wegener was best-known for his achievements in <span>meteorology and as a pioneer of polar research, but today he is most remembered as the creator of the theory of the continental drift. This idea was controversial in the beginning, but today, scientist believe that Pangaea really existed during the late Paleozoic and early Mesozoic eras.</span>
