How did the Earth look in ancient times?


                        The Earth’s surface looked similar to its appearance today, although the continents did not exist because they were still joined together in one supercontinent called Pangaea. When Pangaea broke up, the continents were formed and they drifted about on the Earth’s crust to their present positions. Ancient plants were very different, and flowering plants and modern trees have developed comparatively recently (about 100 million years ago). Plant-eating animals would have fed on ferns, horsetails and primitive trees called cycads.



                       Swamp and bogs covered large areas, and mountains were much higher than they are today, because they had not yet been worn down by erosion. Volcanic activity was greater too, and this would have caused earthquakes and eruptions, which may have influenced the extinction of some animals.
