All the Water in the World How much of this represents all the freshwater in the world? How much of this is frozen and inaccessible to humans? How much of this can plants, animals, and humans use? All the Water in the World All the water in the world All the FRESH water in the world (3%) All the FRESH water in the world that is not frozen in glaciers or icecaps All the FRESH water in the world that is available for humans and plants to use

Less than 1% of Earth’s water supply is ready for human use

CYCLES What is a cycle? What are some cycles in our lives? A cycle is a repeating event or process What are some cycles in our lives? What cycles have we learned about this semester?

What are the different places water can go as it moves through and around the Earth?

Stations! We are going to get our information from stations today Please place your belongings under your table (between the two silver bars) Move swiftly throughout the stations so that we can listen to music while we work!

WATER CYCLE The sun provides all of the energy that drives the water cycle. As a result of the water cycle, water constantly moves among the oceans, the atmosphere, the solid Earth, and the biosphere. This unending circulation of Earth’s water supply is the water cycle.

EVAPORATION The sun heats up water molecules. They then rise into the atmosphere.

CONDENSATION As the water molecules rise, they become cooler, and condense to make clouds.

PRECIPITATION Eventually gravity makes the water molecules fall back to earth as precipitation.

INFILTRATION Once the water reaches earth’s surface, gravity forces the water to sink into the soil, called infiltration.

TRANSPIRATION Just like us, plants sweat. The loss of water from plants leaves, stems and roots is called transpiration.

RUNOFF If water cannot sink into the soil, it will move downhill across the land, in a process called runoff.

Application Questions When you are done with the vocabulary, answer the questions on the back of your handout These questions should be answered in complete sentences Talk with your group about questions you are struggling with!

Fill In the Blanks!

WATER CYCLE BALANCE How does the law of conservation of matter relate to the water cycle? Water is never created or destroyed. It just cycles through different forms.

WATER CYCLE BALANCE Because water is never created or destroyed, the water cycle is balanced. Balance in the water cycle means that the average annual precipitation over Earth equals the amount of water that evaporates

WATER CYCLE BALANCE There are local imbalances Ex: over the ocean, more water evaporates than precipitates Ex: over land, more water precipitates than evaporates

How does surface effect the water cycle? What happens when you build a parking lot? 26

EXIT TICKET What process is directly responsible for the formation of clouds? What is infiltration? Sometimes, water that lands on the street picks up oil and other trash and carries this to a storm drain, where it is dumped into our rivers. The rivers move across the surface of the Earth until they reach the ocean. What process of the water cycle is responsible for the movement of this pollution? On a farm, gasoline was being stored in a large container. The container broke, and gasoline leaked out onto the land. Should the farmer be concerned about gasoline getting into his well? Why or why not?
