Wegener's theory was based on a number of observations, including:
* The fit of the continents: The coastlines of some continents, such as South America and Africa, seem to fit together like pieces of a puzzle.
* The distribution of fossils: Fossils of the same species have been found on different continents, even though these continents are now separated by oceans.
* The presence of similar rocks and minerals: Similar rocks and minerals have been found on different continents, even though these continents are now separated by oceans.
Wegener's theory was not widely accepted at first, but it has since gained support from a number of other lines of evidence, including:
* Paleomagnetism: The study of the Earth's magnetic field has shown that the continents have moved relative to each other over time.
* Plate tectonics: The theory of plate tectonics explains how the continents can move around the Earth's surface.
Today, the theory of continental drift is considered to be one of the most important theories in geology. It has revolutionized our understanding of the Earth's history and has helped us to explain a wide range of geological phenomena.
