GEOG 131 Chapter 7.9, 7.10: Geog 131 Ch 7.9 Notes
Document Summary
Aerosols- tiny drops of liquids and solids in the atmosphere. Point source- if it comes from a single, relatively localized site. Non point source- if it comes from multiple sources. Local climate- greatly in uenced by how urbanized the area is. Urban heat island- cities affecting their local climate by being warmer than rural areas. Secondary pollutant- some emitted pollutants react with sunlight, water, or other contaminants to create a new pollutant: can be more harmful than the original pollutant. Human geography- spatial distribution of population density and activities of people. Oasis effect- humidities raising compared to the surrounding desert. Urban canyon- winds being stronger locally if they blow parallel to streets which allows them to be channeled between buildings.
