Answer:
1-Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.
2-It also suggested Steno's Law of Superposition (as it is known today). The oldest layers of rocks are at the bottom and newer layers are formed on top of the old. This means that geologists can read these layers as a time sequence. ... His Law of Superposition led to his title as the Father of Geology.
3-By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
