                           LESSON CONTENT

Water is very essential to man, animals and plants to survive in their environment for growth and to cool its body.

Human use water also for cooking, eating, source of electricity, processing of goods.


THE WATER CYCLE

Water cycle is the movement of water in liquid or gaseous state from the earth surface to the atmosphere and back to the earth.

The Heat from the sun causes water to move as gas or vapour from the surface of the earth into the sky by evaporation. The water becomes cool and forms cloud by condensation, the cloud sends down the water back to the surface of the earth as rain.

                           THE FORMATION OF RAIN

The major sources of water are lakes, River Sea, ocean etc.

The process of rain formation are as follows:

  1. When rain falls, some of the water goes to the streams, rivers, lakes, ponds, and sea while some water will fall on leaves and holes in trees.
  2. The heat from the sun changes some of the water to vapour or gas (Evaporation). This vapour is carried up into the atmosphere.
  3. The rising vapour meet cooler air in the sky and then forms clouds (condensation).
  4. When the cloud becomes too big and heavy for the air to carry, it falls back to earth as rain.
