Hydroelectricity uses dams to generate electricity. How do dams negatively impact the water cycle?
a) A lake forms which provides water for animals.
b) Creating lakes where people can boat and swim.
c) Droughts can occur downstream with some streams completely drying up.
d) Providing electricity that does not pollute the air.

b) The overall amount of water in all forms increases.
c) The overall amount of water in all forms decrease.
d) Atmospheric water vapor amounts.

When irrigation is used to water crops often nutrients that are important in growing crops are washed away. This causes the use of more fertilizers by farmers to grow crops successfully. How does this negatively impact the water cycle?
