GEOLOGY

Detailed explanation-1: -Fossils also show how animals changed over time and how they are related to one another. Fossils can’t tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior. Fossils are very rare.

Detailed explanation-2: -Fossils give us a useful insight into the history of life on Earth. They can teach us where life and humans came from, show us how the Earth and our environment have changed through geological time, and how continents, now widely separated, were once connected.

Detailed explanation-3: -All scientists agree that items made by humans, such as buildings, paintings, books, pottery and coins, are not fossils. These artefacts are studied by archaeologists, not paleontologists.

Detailed explanation-4: -Some animals and plants are only known to us as fossils. 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.
