(d) The temperature of the atmosphere is rising.
(a) Deposits of fossil fuels are limited as it takes millions of years to form fossil fuels.
(b) Solar energy is a vital part of the energy cycle on the Earth. Solar energy is absorbed by animals and plants, and stored in the form of chemical energy. After the animals and plants die, this energy remains in them and is available to us in the form of fossils and other fuels. Due these reasons, solar energy is the sources of all forms of fuels on the Earth.
(c) Natural gas lights up quickly and burns without leaving behind any solid substances. Also, it is easy to transport from one place to another using pipes, over a long distance. Due to these reasons, natural gas is convenient to use as a fuel.
(d) The temperature of the atmosphere is rising due to the following factors:
(i) Burning of fossil fuels
(ii) Rapid industrialization
(iii) Cutting of trees
