Climate
Test 1 Part 6
| Term | Definition |
|---|---|
| Weather | short term conditions of the atmosphere in a local area |
| Climate | average weather in a given region over a long period of time |
| Regional | ____ differences in temperature and precipitation collectively determine which organisms will survive |
| Troposphere | 0 to 10 miles above the Earth. Mostly Nitrogen, Oxygen, and Water Vapor. Temperature goes down as you go up. |
| Stratosphere | 10 to 30 miles. Temperature rises as you go up (due to high UV radiation hitting the upper levels). Ozone layer occurs here (absorbs most UV-B and UV-C). |
| Mesosphere | 31 to 65 miles. Temperature decreases as you move up. |
| Thermosphere | 65 -370 miles. Temperature increases as you move up. Blocks most x-rays and some UV. Has charged molecules that are attracted to the poles and produce light when hit by solar energy northern/southern lights |
| 1.Troposphere 2.Stratosphere 3.Mesosphere 4.Thermosphere | What are earths 4 atmospheres/layers? |
| aurora borealis (northern lights) and aurora australis (southern lights) | northern lights/southern lights |
| 1. Solar Energy Angle 2. Surface Area Impacted 3. Albedo | Name 3 reasons for unequal earth heating |
| Solar Energy Angle | at the equator goes through less atmosphere (shorter distance) so more energy reaches the equator than mid latitudes and polar regions |
| Surface Area Impacted | more concentrated at the equator—more energy per square meter than other regions |
| Albedo | % of incoming light that is reflected from the surface (higher albedio, higher reflection) |
| • Water • Sea ice • Asphalt • Forest • Snow • Clouds • Grasslands | Rank based on % albedo: snow, forest, water, grassland, asphalt, sea ice, cloud |
| Air Density | warm air is less dense than cold air, so warm air will rise |
| water vapor capacity. Warm days are more humid. | Warm air has higher ____ _____ ______ so warm days are more humid |
| Saturation Point | max. amount of water vapor~ increases w/temperature |
| Adiabatic cooling and heating | air rises, pressure lowers, air expands, and temperature decreases (cooling), air sinks, pressure increases, temperatures increase (heating). |
| Latent Heat Release | when water vapor condenses to liquid water- the air becomes warmer. |
| Du Point | gas goes to liquid |
| Coriolis Effect | deflection of an objects path due to Earth’s rotation |
| Controlled by temperature, gravity, winds, Coriolis effect, and continents | What are ocean currents controlled by? |
| Gyres | large scale circulation patterns (clockwise in north, counterclockwise in south) |
| Upwelling | support highly productive ecosystems- usually on west coasts where surface waters diverge (deeper water fills in when water moves away) |
| Global Warming | ____ _____ is the increase of Earths average surface temperature due to greenhouse gases (mostly CO2 and CH4) that collect in the atmosphere. |
| Greenhouse Gases | keep heat close to the earth’s surface making it livable for humans and animals. |
| 800,000 | 1. There is more carbon dioxide in the atmosphere today than at any point in the last _____ years |
| 4%, 25% | Through Americans make up just ___ of the world’s population, we produce ___ of the carbon dioxide pollution from fossil fuel burning |
| EPA | The ___ has both the authority and responsibility to reduce pollution from electric power plants under the Clean Air Act, adopted in 1970 |
| 8 inches | Since 1870, global sea level has risen |
| Glaciers have shrunk, ice on rivers/lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner | Observable Effects of Climate Change |
| Heat Waves | caused by global warming present greater risk of heat-related illness and death, most frequently among people who are elderly and very young |
| 2F, 1.5F, 5% | According to the US Global Change Research program; the temperature in the US has increased by ____ (globally___) in the last 50 years and precipitation has increased by ___% |
| Earth moves 1035 miles an hour at the equator 181 miles at 80 N. lat | How fast does earth move at the equator and at 80 N. lat? |
| Hadley Cells | air sinks at 30N lat, 898 (miles per hours), as it moves to the equator the surface speed increases to 1,038 miles per hour |
| 898, 1038 | In Hadley Cells, air sinks at 30N lat, _____ (miles per hours), as it moves to the equator the surface speed increases to ______ |
| temperature, gravity, winds, Coriolis effect, continents | What five things control ocean currents? |
