Answer:
1) In a easy way Natural resources are the resources that we get from Nature.
They are two types Renewable and Non renewable
Renewable : Sunlight
Non renewable: Coal and petroleum
2)Coal formation takes place when many many years ago the dead bodies of several plants and animals get buried under the soil and due to hot temperature and pressure they form into coal.
3)Carbon dioxide.
4)Fossil fuels are the resources that we obtain from the remains of fossils.
Like Coal and petroleum.
Answer:
1. Natural resources are those which are obtained from nature or available to us from nature.
Example:- Renewable resources- Sunlight.
Non - renewable resources - Coal and Petroleum.
2. Coal was formed from plant remains got buried deep under the earth's crust. ber a large period of time , the chemical and physical properties of these plant remains were changed through geological actions that led to the creation of this solid material. The process, of conversion of dead plant materials into coal, is called carbonisation.
3. Coal gas.
4. Fossil fuels are those that were formed over a period of million of years, by the action of heat and pressure on the remains of dead plants and animals.
