Good Morning everyone! Gather your umbrellas for todays lesson: The Water Cycle.
The rain is called precipitation. Precipitation is when the clouds in the atmosphere become so heavy that it starts to release water in the form of rain, sleet, hail, or snow.
So the rain right now is precipitation?
When the rain hits the water, it can flow off into a river which can go into the ocean. This is called run off. The water droplets can also go onto the plants, which we will talk about later.
That is cool.
Vocabulary Word: Water Cycle The changes to water when it evaporates into the air, condenses, and then precipitates.
Look! It stopped raining!
Yep! Now the water vapor on the flowers can go up into the atmosphere. This process is called transpiration.
If you look at the stream beside me, some of the water will evaporate. This means that some of it will change into a gas, caused by the heat from the sun.
Vocabulary Word: Atmosphere The blanket of gases around a planet.
The evaporated water will rise up into the sky and cause a process called condensation. This is the cooling of water in the atmosphere and it will turn back into a liquid. This is how clouds get heavy, and how it starts to rain again.
Vocabulary Word: Run Off Rainfall that is not absorbed by soil and then it travels to the ocean.
Vocabulary Word: Transpiration The passage of water vapor from a plant to the atmosphere.
Vocabulary Word: Evaporation The process that occurs when water changes from a liquid to a gas, caused by heat.
Vocabulary Word: Condensation The cooling of water in the atmosphere changing from gas to a liquid.
