Step-by-step explanation:
From looking at maps over the years, Alfred Wegener observed that the countries/continents could fit together and they almost looked like pieces of a puzzle that connect to the greater picture of things (we refer to Pangea) Also, he proved his theory of continental drift from various pieces of evidence. For example, one of the biggest pieces of evidence were the fossils found on different continents. For example, an organism that wasn't even native to a country was found there through old fossil remains.
