GEOLOGY

Detailed explanation-1: -Scientists learn this information by determining the age of fossils that are discovered and studying other clues found in the same soil layers where they found the fossils. Fossils of human remains and of plants and animals provide insight into how people lived in the past.

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: -Fossils help researchers learn about plants and animals that existed long ago, having since faced extinction or evolution to modern species. Through unearthing and studying their remains, paleontologists learned what they know today about dinosaurs and saber-toothed tigers.

Detailed explanation-4: -Paleontology is packed with mysteries about living things such as plants and animals that lived thousands, millions, and billions of years before the first modern humans. To solve these mysteries, paleontologists use fossils.
