Hi! My name is Dewy the Rain Drop. Today, the water cycle is going to be explained to you!
The Sun plays a big role in the water cycle. Dewy is originally from the ocean. When the Sun's rays heat the ocean, lakes, or rivers, the water evaporates. Evaporation is the process of changing surface liquid water into a gas. Once the water evaporates, it turns into hot water vapor.
Transpiration is another way in which liquid water is evaporated into water vapor from plants. Plants carry water through their roots and to the undersides of their leaves where it is released as water vapor.
Once the water vapor rises into the atmosphere condensation occurs. Condensation takes place when cooler air temperatures cause the water vapor to condense into tiny water droplets that form clouds.
It's Dewy here and I have made it back to the water. Now I am ready to do the water cycle all over again!
The atmosphere plays a big role in the water cycle. Evaporation and Transpiration change liquid water into water vapor which ascends into the atmosphere due to rising winds. Then the water vapor is condensed into clouds due to the cool air.
Precipitation occurs when clouds become heavy with water droplets and these water droplets then fall back to the earth in the form of rain, snow, sleet, and hail.
Runoff is water from rain and melted snow that flows over land surfaces and into channels that carry the water back to streams, rivers and oceans.
