GEOG 131 Lecture Notes - Lecture 29: Smog, Nonpoint Source Pollution, Diurnal Temperature Variation
Document Summary
Tundra biome: gradation from dry tundra in the uplands to aquatic tundra close to standing water- all underlined in permafrost, above latitude of tree line or above elevation. Air pollution- gases, liquids, and solids emitted by human and non-human activities into the atmosphere and are harmful to humans or other aspects of the ecosystem. Aerosols- solid and liquid particles: interact with sunlight > potential to in uence climate. Pollution from burning fossil fuels (coal speci cally) and from metal smelters. High emission areas mostly from coal red generation of electricity. Contributes to acid rain and respiratory issues: o3 (ozone) Subject to regulation under clean air act. How climate and human geography affect distribution: sunny places and concentrated individual activity. Factors: type and proximity to source. Source can be point or non-point source: atmosphere conditions. Can trap or disperse pollution: topography. Can back dispersion of air pollution or guide winds that help disperse air pollution.
