1.8. Human Impacts on the Hydrologic Cycle

Try these first

1. 1.

   What effect does urbanization have on the hydrologic cycle?

   Hint

   Think about how cities are built.

2. 2.

   How does deforestation affect transpiration?

   Hint

   Consider the role of trees in releasing water.

3. 3.

   What is a primary effect of urbanization on the hydrologic cycle?

   • Increased infiltration
   • Increased runoff
   • Decreased water quality

   Hint

   Consider how concrete affects water movement.

4. 4.

   Deforestation reduces which process in the hydrologic cycle?

   • True
   • False

   Hint

   Think about which processes trees support.

5. 5.

   Evaluate the long-term hydrologic impacts of urban development on a previously forested area.

   Hint

   Consider the environmental changes brought by construction.

6. 6.

   Propose a strategy to mitigate the effects of climate change on hydropower systems reliant on the hydrologic cycle.

   Hint

   Think about how to balance energy needs with ecological health.
