Evaporation
Explanation:
Evaporation is one change that would cause more water to evaporate from a stream.
Evaporation is a phase change in which liquid is changed into its gaseous form.
- When a substance is heated from solid to liquid, it melts.
- After melting, additional heat causes a phase change that allows for the liquid to change to gases.
- In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
- This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.
