<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Different steps of water cycle include evaporation, transpiration, condensation, precipitation and surface run-off.</font></font></font></font>
<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Evaporation - The water present on the surface of oceans evaporates by the sun’s heat. This process of conversion of water from liquid state to vapour state is called evaporation. Evaporation also takes place from wet clothes, fields, ponds, lakes and rivers.</font></font></font></font>
<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Transpiration - Plants take in water from the soil to prepare their own food and also for other life processes. They release excess water into air in the form of water vapour by the process of transpiration.</font></font></font></font>
<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Condensation - The evaporated water is carried away by warm air. As the warm air moves higher from the surface of the Earth, it starts to cool down. This water vapour condenses to form tiny water droplets which float in air to form clouds or fog.</font></font></font></font>
<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Precipitation - All these droplets collect to form bigger drops of water. Bigger water drops come down ads rain by the process of precipitation. If the air is too cold, the water drops can become snow or hail and may settle on the top of a mountain. When these snow or hail melts, they can become part of a river or a stream.</font></font></font></font>
<font face="Arial, sans-serif"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;"><font size="3"><font style="box-sizing: inherit; outline: none; user-select: initial !important; max-width: 100%; overflow: hidden;">Surface run-off – Some amount of rain water is absorbed by the soil and settles down as ground water. Most of the rain water flows down the hills and mountains to collect into rivers, lakes or streams. Rain also washes away the topmost layer of the soil into water bodies. </font></font></font></font>
