GENERAL GEOLOGY

Detailed explanation-1: -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-2: -Fossils don’t just show how living things have changed; they can also help us understand how the Earth has changed. Over millions of years the Earth’s surface shifts and changes. For example, rocks that once formed the seafloor might be forced up to form a mountain range.

Detailed explanation-3: -Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.

Detailed explanation-4: -Paleontological resources, or fossils, are any evidence of past life preserved in geologic context. They are a tangible connection to life, landscapes, and climates of the past. They show us how life, landscapes, and climate have changed over time and how living things responded to those changes.

Detailed explanation-5: -The study of fossils broadly called paleontology helps in understanding important phenomenons like how life originated on Earth, changes in climate, lifestyle and culture, etc.
