The importance of the Sun
Do you see the Sun in the sky in the morning everyday ? Do you know the importance of the Sun ? The Sun is the main source of the energy on the Earth and the solar energy is the cleanest form of the energy .
The Sun is very important in the plants growth . The Sun helps the plants to make their own food by the photosynthesis process .
The Sun provides us with the heat to warm our bodies .
The ٍSun provides some animals and humans ( that feed on plants ) with food as it helps the plants to make its own food by the photosynthesis process .
The Sun is used in heating water and warming houses by the solar heater which changes the solar energy of the Sun into the heat energy . The heat energy is used in warming houses and heating water .
The Sun is very important in the formation of the clouds , the rain and the winds .
When the Sun evaporates the water in the seas , the lakes and the oceans , the water vapour is formed . and the clouds are formed When the water vapour rises in the sky , it cools and condenses forming the clouds .
The Sun’s heat causes the difference in the temperature in some areas , So the winds are formed .
The clouds move by the effect of the winds and when the volume of the water drops in the clouds increase and the air can not carry them , So the rain falls .
The Sun is very important in the formation of the petroleum oil and the coal . It is one of the main factors in the formation of the fuel .
The Sun helps in the formation of fuel to operate the machines .
It is advisable to expose the children to the Sun rays for suitable periods of time as the Sun emits ultraviolet rays that help in the formation of vitamin ” D “ that is necessary for the bones growth .
The Sun is used to generate electricity by the windmills .
The windmills change the wind energy into the electric energy .
The wind that is produced by the Sun is used in rotating the windmills which are used to operate the generators ( dynamo ) to generate the electricity .
So , We can not live on Earth without the Sun .
