Ice can be changed into water by melting. Water can be changed into water vapour by evaporation. Water vapour can be brought back to water by condensation. water can also be changed in to ice by freezing.   2.     What is water cycle? Explain it with labelled diagram. The cycle that involves the change of water into water vapour and then into water again in nature is called the water cycle. It is the process by which water circulates between the sky and the earth in a continuous cycle.       ICE Heating     Water heating     Water vapour     Cooling Cooling     3.     What do you mean by purification of water?

  LESSON – 10 SUN AS A RESOURCE I.                   DIFFERENTIATE BETWEEN:- 1.     Renewable and non-renewable source of energy Sources of energy that can be used again and again are called renewable source of energy. Natural resources such as coal, petroleum and natural gas form naturally beneath the earth very slowly. The supplies of all these sources are limited and once consumed cannot be made easily again. These are called non-renewable sources of energy.   2.     Solar energy and wind energy. The energy we get from the sun is called solar energy. We get energy from the sun mainly in the form of heat and light. Solar energy captured by solar panels, wind energy is used in windmills to grind gains and generate electricity.     II ANSWER THE FOLLOWING QUESTIONS:-   1.     Why is sun said to be the main source of energy? The sun is the major source of energy on the earth. We get energy from the sun mainly in the form of heat and light. The energy we g
