RE: ONLINE HELP FOR STUDENTS IN THEORY
"Water Cycle" is made up of a few main parts: evaporation (and transpiration), condensation, precipitation, collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.
Evaporation is the change of water from a liquid to a gas. Water is continuously evaporating from the surface of the Earth, literally pumping more and more water vapor into the atmosphere. Averaged across the entire Earth, water evaporates from the surface at a rate of about 3 millimeters per day (about 1/8 of an inch). Over the tropical oceans, the value is much larger; over cold surfaces, it is much lower; and over deserts it is almost zero, since there is little or no water to evaporate. This change of phase (from a liquid to a gas) requires heat, called the "latent heat of condensation". When water evaporates, it removes heat, lowering the temperature of the surface. For both water and land surface, most of this heat energy comes from the surface, not from the air. Evaporative cooling, along with convection, helps keeps the surface of the Earth from getting too hot.

Dear parent,

Check the illustration on the topic.

I have no idea as which class is your daugther in. So, I have just highlighted you the basic information on EVAPORATION. If your daugther is doing 12th grade or Graduation, do let me know so that I can prepare a professional project on the topic.
