Learning Goal • After reading and summarizing this presentation, and labeling a diagram, you should be able to define and explain the following terms: • evaporation, transpiration, condensation, precipitation, infiltration, evapotranspiration, and ground water. I have to know ALL THOSE??!!?
Directions • Read each slide. • Complete each definition on your Water Cycle notes sheet. YOU WILL HAVE TO RESTATE WHAT IS ON THE SLIDE IN YOUR OWN WORDS! Oh, good, there’s a sheet to take notes on!
The water cycle is the circulation of water between the earth’s oceans, atmosphere, and land, by evaporation, condensation and precipitation. The Water Cycle Definition
Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet. The Water CycleJust read this!
Evaporation occurs when the sun heats up liquid water and changes it to a gas. Water that evaporates from Earth’s oceans, lakes, rivers, and moist soil rises up into the atmosphere.
The process of evaporation from plants is called transpiration. (In other words, it’s like plants sweating.)
Evapotranspiration • Water goes from the land to the atmosphere by evaporation from the soil and other surfaces, and by transpiration from plants.
As water (in the form of gas) rises higher in the atmosphere, it starts to cool and become a liquid again. This process is called condensation. When a large amount of water vapor condenses, it results in the formation of clouds.
When the water in the clouds gets too heavy, the water falls back to the earth as rain, snow, or hail. This is called precipitation.
When rain falls on the land, some of the water is absorbed into the ground forming, pockets of water called groundwater. Most groundwater eventually returns to the ocean. Other precipitation runs directly into streams or rivers. Water that collects in rivers, streams, and oceans is called runoff.
Infiltration • Infiltrationis the process where precipitation or water soaks into soil and moves into rocks through cracks and pore spaces. Most rainwater and snow end up infiltratedinto the ground.
Now label your diagram on the other side of your notes sheet. • When you are finished, ask to see an Answer Key. Check your work. • Then click go back to the class webpage. • Open the Google Classroom link and follow the directions in the Template for the Water Cycle, to create a slide show.
