1Q-The thin layer of gases around Earth. It provides oxygen, absorbs radiation and moderates climate, transports and recycles water and nutrients.
2Q-Patterns of atmospheric conditions across large geographic regions over long periods of time.
3Q-Bottommost layer (7 miles). Air for breathing, weather, the air gets colder with altitude. Tropopause = limits mixing between troposphere and the layer above it.
4Q-7-31 miles, above sea level. Drier, less dense, with little vertical mixing. It becomes warmer with altitude, and contains UV radiation-blocking ozone (10-19 miles) above sea level.
5Q-31-56 miles above sea level, extremely low air pressure, temperature decreases with altitude.
6Q-Atmosphere's top layer, extends upward to 300 miles.
7Q-The force per unit area produced by a column of air.
8Q- ratio of water vapor air contains to the amount it could contain at a given temperature. High humidity makes it feel hotter than it really it.
9Q-What is the Chemical Composition of the Earth's Atmosphere?
10Q-How is humidity related to heat index?
11Q-Convective cells near the equator. Surface area warms, rises, and expands.
12Q-Lift air and create precipitation at 60 degrees latitude north and south. Conditions at the poles are dry.
13Q-An area near the tropics or equator with few winds.
14Q-Between the equator and 30 degrees, they blow East → West. They weaken periodically, leading to El Niño conditions.
15Q-From 30-60 degrees latitude, blow West → East. People used these winds to sail across the ocean wind and convective circulation in ocean water maintain ocean currents and create violent storms.
16Q-They form when winds rush into areas of low pressure. Warm, moist air over tropical oceans rise.
17Q-Winds turn counterclockwise in the Northern Hemisphere, drawing up huge amounts of water vapor. This falls as heavy rains.
18Q-Form when warm air meets cold air. Quickly rising warm air forms a powerful convective current (spinning funnel).
19Q-Air temperature goes down as altitude increases, and warm air rises causing vertical mixing.
20Q-Gases and particulate material added to the atmosphere. This can affect climate or harm people or other organisms.
21Q-The release of pollutants.
22Q-Pollution outside: has recently decreased due to government policy and improved technologies in developed countries. Developing countries and urban areas still have significant problems.
23Q-More diffused, consisting of many small sources (automobiles).
Point source air pollutant: Specific spots where large quantities of pollutants are discharged (power plants, factories).
24Q-Directly harmful and can react to form harmful substances (soot and carbon monoxide)
25Q-Form when primary pollutants interact w/ components of the atmosphere. Tropospheric Ozone (heat and radiation) and Sulfuric Acid (causing acid rain).
26Q-The time a pollutant stays in the atmosphere. Tropospheric ozone and carbon monoxide = weeks/months. Pollutants w/ brief residence times exert localized impacts over short time periods. Particulate matter, automobile exhaust, etc. Pollutants w/ long residence times exert regional or global impacts, and pollutants cause climate change or ozone depletion.
27Q-Naturally Occurring Air Pollutants
28Q-Sets standards for air quality, limits on emissions, provided funds for pollution-control research, allowed citizens to sue parties violating the standards.
29Q-Strengthened regulations for auto emissions, toxic air pollutants, acidic deposition, tropospheric ozone depletion.
30Q-These are pollutants that may cause especially great threats to human health.
31Q-Clean Air Act: Six Criteria Pollutants
1Q-The thin layer of gases around Earth. It provides oxygen, absorbs radiation and moderates climate, transports and recycles water and nutrients. 1A-Atmosphere
