1) Natural resources are resources that exist without any actions of humankind. This includes all valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land along with all vegetation, and animal life.
2) Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules. Minerals are deposited from salty water solutions on Earth's surface and underground.
3) Mineral like copper is used in electrical equipments as it is good electrical conductor. Clay is used to make cement etc which helps in constructing roads. Fibreglass, cleaning agents are made by borax.
4) a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
