4. SECTION 2
The Hydrosphere
Question:
What roles do evaporation, condensation, and precipitation play in the hydrologic cycle?

5. The Hydrosphere SECTION 2 Condensation:
as water vapor rises it forms droplets.
Evaporation:
energy transforms water into vapor.
Precipitation:
droplets may become heavy enough to fall as rain, snow, or hail.
Surface Water

6. Question: What are the causes and effects of air pollution?
SECTION 3
Natural Resources
Question:
What are the causes and effects of air pollution?

7. Natural Resources SECTION 3 Effects:
Causes acid rain, which can damage trees and kill fish in lakes; may damage the ozone layer; presents a threat to human health
Causes: Factories and automobiles burn fuel, releasing smoke and fumes into the atmosphere.
