Alfred Wegener tried to prove that Earth's landmasses move over time using fossil evidence. His idea was called continental drift, which suggested that the continents were once joined together, forming a supercontinent called Pangaea. To support his theory, Wegener studied the distribution of fossils on different continents. He noticed that similar plant and animal fossils were found on opposite sides of the Atlantic Ocean, suggesting that these continents were once connected. Additionally, the matching geological features and rock formations across different continents further supported the idea of continental drift. Although his theory was initially met with skepticism, it eventually led to the development of the modern theory of plate tectonics, which explains the movement and interaction of Earth's landmasses.
