AP Environmental Science / Unit 5: Land and Water Use
5.10 Impacts of Urbanization
Notes
- Impervious surfaces (pavement) increase runoff and flooding.
- Urban heat island: cities are warmer.
- Urban sprawl spreads development outward, increasing car use.
- Saltwater intrusion can happen when coastal aquifers are overpumped.
Practice
Cities are warmer than surrounding areas because:
Urban heat island.
Pavement increases:
Water can't soak in.
Overpumping coastal aquifers can cause:
Seawater moves into the aquifer.
