Answer:
The German Meteorologist who pioneered the theory of continental drift and plate tectonics was Alfred Wegener.
Step-by-step explanation:
Alfred Wegener was a German meteorologist who in 1912 proposed the theory of continental drift, in which he argued that continents on both sides of the Atlantic Ocean were separating. In 1915, Wegener published the theory that about 200 million years ago, a giant supercontinent, Pangea, had disintegrated, based on the similarity of the coastlines of South America and Africa.
Many geologists ridiculed Wegener for his ideas, saying he could not explain how the continents were moving. It was only after the expansion of the seabed was discovered in the mid-twentieth century that Wegener was recognized for the merits of being a precursor to plate tectonics theory.
