3. When we flush the toilet why should we say “see you later”?

4. Aim: How does the earth recycle water?
Topic: Water Cycle and Climates
Main Idea: Water Cycle

5. 1a) What is the water cycle?

6. Using the picture and the reading define the following words:
Hydrologic cycle= process by which water travels from the air to the earth and returns back to the atmosphere
Water table= top level of groundwater
Aquifer= water-bearing layer of rock
Runoff= water running along the surface
Condensation= from gas to liquid
E) Transpiration= moisture entering the atmosphere from plants and trees

7. Terms continued…
Saturated zone= point where all pore spaces of rock are filled with water (below the water table)
Transpiration= moisture entering the atmosphere from plants and trees
Infiltration= water soaking downward through the soil
Evapotranspiration= all moisture entering the atmosphere regardless of the source

9. What can happen to water
Conditions
Evaporation
Temperature is high
Relative humidity is low
 Infiltration
 Ground is unsaturated
Slope is low
 Runoff
Ground is saturated and impermeable
Slope is high
Precipitation is heavy
 Stored
Ground is unsaturated and flat

10. Rivers, wetlands, and the lake
Underground, glaciers, and clouds
transpiration
Evaporation
Groundwater, evaporation, lakes,
rivers, streams, oceans, frozen as glaciers
Rain, snow, hail, frost, dew
The sun triggers evapotranspiration to return the water to the
atmosphere. Gravity pulls water to be stored as groundwater.
It is used as drinking water, irrigation and for use in factories.
It is pumped out of wells dug through aquifers
One well is shown. It is being used for irrigation of crops.
Farming (runoff carrying pesticides), factory pollution returning
into the ground by the lake.
The farm would be using polluted water from the factory.
