Answer:
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Heat from the sun, or solar energy, powers the evaporation process.
Explanation:
Evaporation occurs when liquid water turns into a water vapor, with about 90 percent of the water going through such a transformation originating from rivers, lakes and oceans. It's easiest to understand the cause of evaporation by considering a pot of boiling water. Once the water in the pot reaches the boiling point, 100 degrees Celcius (212 degrees Fahrenheit), water vapor in the form of steam can be seen rising from the pot. Heat is the cause of evaporation, and is required to separate water molecules from one another. While the process doesn't often occur as rapidly or as obviously in nature as it does with the boiling pot, heat is still at work wherever there is a body of water, separating water molecules so they can be carried upward, transforming water from a liquid to a gas.
