Explanation: Water is the one of the most important resources which is present on earth and is a gift for all of us from nature. Water is present on earth in the same quantity as it was when earth was created. Water cycle comprises of some basic steps which include:- 1 Evaporation First of all Water is evaporated from the rivers, lakes, oceans and other water bodies present on earth under open sky especially during the summer time when sun is burning at its highest in the year.

What is a simple definition of the carbon cycle? Here's how it works: Remember from chemistry class that molecules in a gas are energetic and move very fast, while those in a liquid move slower.
In order for condensation to happen, the water vapor molecules must release energy so that they can slow their movement. This energy is hidden and is therefore called latent heat. The opposite of condensation is evaporation.
Evaporation is the process of changing liquid water into water vapor a gas. It transports water from the Earth's surface to the atmosphere.
3.2 Condensation and Evaporation
It should be noted that solids, like ice, can also evaporate or be transformed directly into a gas without first becoming a liquid. For water molecules to go from a liquid to an energized gaseous state, they must first absorb heat energy. They do this by colliding with other water molecules. Evaporation is called a "cooling process" because it removes heat from the surrounding air. Evaporation in the atmosphere is a crucial step in the water cycle.
Water on Earth's surface will evaporate into the atmosphere as energy is absorbed by liquid water. Water molecules that exist in the liquid phase are free-flowing and in no particular fixed position. Once energy is added to water by heat from the sun, the bonds between the water molecules gain kinetic energy or energy in motion.
This process of water evaporating from the surface of the Earth happens continually and continually transports water vapor into the air. The rate of evaporation depends on air temperature, wind speed, cloudiness.
