Final answer:
The first person to suggest the possibility of continental drift was Alfred Wegener, a German meteorologist and astronomer.
Step-by-step explanation:
The first person to write about the possibility of continental drift was Alfred Wegener. Wegener, a German meteorologist and astronomer, proposed the idea of continental drift in 1920. He suggested that the continents could have once been together and then torn apart, based on the observation that the coastlines of North and South America fit well against the coastlines of Europe and Africa. Wegener's evidence also included the similarities between fossils found in South America and Africa, as well as resemblances among living animal species on different continents.
