Evaporation is the process where liquid water turns into vapor when heated, occurring at any temperature. Condensation is the reverse process where water vapor cools and changes back into liquid, forming droplets.

Water kept under a tree still evaporates because it absorbs heat from the surrounding air and ground. Even in the shade, the ambient temperature provides enough energy for water molecules to evaporate gradually.
Without water on Earth, all living organisms would perish. Plants, animals, and humans rely on water for survival. The absence of water would stop the water cycle, resulting in no rain, agriculture, or life.
“A Journey through States of Water,” Chapter 8, explains how water changes between solid, liquid, and gas through freezing, melting, evaporation, and condensation. It highlights the water cycle, its importance, and water conservation.
Absence of trees disrupts the water cycle by reducing transpiration and increasing runoff. Without trees to absorb and release moisture, less water evaporates into the atmosphere, leading to reduced precipitation and potential drought.
