Explore

• The Environmental Protection Agency
• Answer the following questions
• Where is water stored?
• How does water move from one place to another?
• What is infiltration?
• What is runoff?
• How does global warming affect the water cycle?
  Use information about the effect of (a) the wet
  cycle and (b) the dry cycle.

13
Explain

• Debrief
• Review questions related to the EPA water cycle

14

• Where is water stored?

Water is stored in oceans, lakes, rivers, and
groundwater.
15

• How does water move from one place to another?

Evaporation, transpiration, condensation,
precipitation.
16

• What is infiltration?

Infiltration is water movement between the spaces
in the soil.
17
What is runoff?

• Runoff occurs when water flows over the ground
  instead of sinking into the ground.

18

• How does global
• warming affect the water cycle?
• Include information about the effect of
• The wet cycle
• The dry cycle

19
Global warming intensifies the water cycle
because the earths surface is a little warmer
and this increases evaporation.
a). Where there is too much water, there is more
water infiltrating and more runoff. This could
cause flooding and negative effects on plants and
animals living in the area.
b). In areas away from a water source more
evaporation and transpiration could dry out the
soil. This could lead to lowered ground water
supply, and have negative effects on the plants
and animals living in the area.

Elaborate

• Create a diagram showing the effects of global
  warming on the water cycle.

Evaluate

• Summarize the effects of human activity on the
  water cycle
• global warming,
• water quality,
• and quantity.
