The molecules literally jump away into the air during the evaporation process. A sunny day provides the heat, and wind also helps to carry away water molecules as vapor. How much water evaporates ...

Evaporation accounted for 61 percent of the ... Heat keeps the water molecules moving and bouncing off each other, rather than condensing — a requirement for rainfall. The result is a cycle ...

It includes observations and conclusions that students are meant to make on their own. Evaporation occurs when molecules in a liquid gain enough energy that they overcome attractions from other ...

In evaporation, a liquid (like water) changes state to become a gas (water vapor). In condensation, a gas (like water vapor) changes state to become a liquid (water). Explain that as water molecules ...
