What is water molecules turning from a liquid into a gas?
- A.
Evaporation
- B.
Condensation
- C.
Precipitation
- D.
Respiration
Correct Answer
A. EvaporationExplanation
Evaporation is the process in which water molecules transition from a liquid state to a gas state. This occurs when the water is heated, causing the molecules to gain energy and escape into the air. Evaporation is a crucial part of the water cycle, as it allows water to be transferred from bodies of water to the atmosphere, where it can eventually condense and form clouds. Precipitation, on the other hand, refers to the process of water falling from the atmosphere to the Earth's surface in the form of rain, snow, or hail. Respiration is the process by which organisms release energy from food, and it is not directly related to the transformation of water molecules.Rate this question:
