The Hydrologic Cycle

·         Evaporation is the process by which a liquid is converted into vapour. This occurs on the surface of a liquid.

·         Transpiration is the process by which plants lose water through their leaves. Water vapour escapes through tiny openings called stomata in the leaves.

·         Evapotranspiration is the loss of water from the land by evaporation and transpiration.

·          Condensation is the process by which vapour is converted into a liquid. In the diagram it refers to water vapour being converted into water droplets in the atmosphere. 

·         Precipitation refers to any of the forms in which water falls from the atmosphere and reaches the ground including rain, snow or hail.

·          Interception is the process where objects such as trees prevent the direct contact of the rain and the ground.

·         Infiltration is the process by which water enters the soil.

·          Surface runoff is the flow of water on the surface of the Earth into water bodies.

·         Percolation is the process by which water moves downward through the soil.

 ·          Water Table is the level at which the ground is saturated with water.
