What are fossils ? How are they formed ?

Ans. 1. Fossils are formed by the burial of dead plants and animals. 

2. When plants or animals die, their bodies get decomposed. 

3. Over time, the skeleton is gradually buried deeper by the overlying sediments. 

4. Slowly, the weight of the sediments, compresses the dead bodies and water is squeezed out of them. 

5. This compressed mass then turns into fossils.
