Wegener used evidence to describe continental drift which of these is evidence wegener used

Answer 1

- Fossil Evidence: Wegener observed that the same fossils of plants and animals were found on different continents which were separated by vast distances of oceans. For example, fossils of the freshwater reptile Mesosaurus were found in both South America and Africa, suggesting that these continents were once connected.

- Rock and Mountain Range Evidence: Wegener noticed that similar types of rocks and mountain ranges existed on opposite sides of the Atlantic Ocean. For instance, the Appalachian Mountains in North America matched the Caledonian Mountains in Europe, indicating that they were once part of the same continuous mountain range.

- Glacial Evidence: Wegener observed that there were glacial deposits and ancient striations found on rocks in areas where glaciers are no longer present. This indicated that these regions were once covered by ice sheets, which could only make sense if the continents were located differently at that time.

- Paleoclimatic Evidence: Wegener studied ancient climates based on evidence such as coal deposits, salt deposits, and tropical plant fossils found in regions that are currently cold or arid. This suggested that those areas were once located in different climatic zones which could only be explained by continental drift.

These pieces of evidence led Wegener to propose the theory of continental drift, suggesting that all continents were once part of a single supercontinent called Pangaea and had gradually moved over time.
