Step-by-step explanation:
The man who composed the Continental Drift Hypothesis is Alfred Wegener, a German meteorologist and astronomer. He proposed the idea in 1915 and provided evidence such as the fit of the continents like pieces of a puzzle, matching fossils and mountain ranges on separated continents, and paleoclimate evidence. Although his hypothesis was initially met with hostility and skepticism, it laid the foundation for the development of plate tectonics.
