Question

​Fossils are mostly present in which type of rock?

Answer 1

Instructions:

• Talk about the formation of fossil fuels

Solution:

1. Fossil fuels are formed by decomposing dead and decaying plant or animal matter underground for millions of years.
2. When any plant or animal dies, soil bacteria start decomposing the matter, which is gradually buried by the layers of sedimentary rock in the earth's crust, increasing the heat and pressure inside. As a result of heat, fossil fuels start forming.
3. Coal, Natural gas, and oil are examples of fossil fuels that take millions of years to form.
