Atmosphere size - CORRECT ANSWER compared to the size of the Earth (104 km), the atmosphere is a thin shell (120 km) Atmosphere Composition - CORRECT ANSWER consists of layers of air that surround the Earth. Including oxygen, other gasses, dust particles, and water vapor. Functions - CORRECT ANSWER Major conduit for transport between oceans & land, controls climate, held on earths surface by gravity, composition evolves, human activities change it, has a structured layer. Atmosphere layers - CORRECT ANSWER Exosphere Thermosphere
(Ionosphere) Mesosphere Stratosphere Troposphere Troposphere - CORRECT ANSWER 8 to 14.5 kilometers high (5 to 9 miles) Air thins in this layer and is denser than in other layers. the temperature drops from about 17 to -52 degrees Celsius closest to the surface of Earth. Nearly all life and all weather occur in this layer. (75% of the atmosphere's mass) The higher up from Earth's surface you go, the colder it gets. Stratosphere - CORRECT ANSWER extends to 50 kilometers (31 miles) high dry and less dense temperature in this region increases gradually to -3 degrees Celsius, due to the absorption of ultraviolet radiation ozone layer absorbs and scatters the solar ultraviolet radiation ninety-nine percent of "air" is located in first two layers every 1000-m 11% less air pressure Mesosphere - CORRECT ANSWER The mesosphere is the coldest layer of the atmosphere. When meteoroids from space enter our atmosphere, this is the layer in which they usually burn up. That might be surprising because it's a pretty thin layer. Thermosphere - CORRECT ANSWER Temperatures in the thermosphere are very high, more that 2000 degrees Fahrenheit. This is where space begins. The International Space Station orbits Earth in this layer.
Results in the aurora borealis (N. hem) or aurora australis (S. lights) Exosphere - CORRECT ANSWER The exosphere is the outermost layer of Earth's atmosphere but there is no exact dividing line between this layer and space. Composition - CORRECT ANSWER Nitrogen (N2, 78%) Oxygen (O2, 21%) Argon (Ar, 1%) myriad of other very influential components are also present which include the Water (H2O, 0 - 7%), "greenhouse" gases or Ozone (O3, 0 - 0.01%), Carbon Dioxide (CO2, 0.01-0.1%), CH4<<<1% and N2O <<<1% Physicists - CORRECT ANSWER physical properties and processes that take place between the radiant energy and atmospheric gases Chemists - CORRECT ANSWER behavior of the chemical materials in the atmosphere the ways lightning causes the formation of substances chemistry of the ozone layer and of chemicals introduced from industrial processes Properties of Atmosphere - CORRECT ANSWER Air has mass (and density) Molecular movement associated with heat causes the same mass of warm air to occupy more space than cool air. So, warm air is less dense. Humid air is less dense than dry air at the same temperature because molecules of water vapor (H2O) weigh less than N2 and O2 molecules displaced. Weather - CORRECT ANSWER Caused by transfer of energy Radiation is method by which Earth receives solar energy
Air moves in response to heating from the sun and movement of water Short term(present) Climate - CORRECT ANSWER This is called atmospheric circulation This interaction of the atmosphere and the oceans creates "CLIMATE" Long Term average of weather (slow changes) Air Movement - CORRECT ANSWER Water vapor rises, expands, & cools It condenses into clouds or precipitation (cooler air can't hold as much water) Atmosphere can lose water by precipitation As air loses water vapor, it becomes dense and air will then fall, compress, and heat. Atmospheric Circulation - CORRECT ANSWER Powered by sunlight - uneven solar heating About 51% of incoming energy is absorbed by Earth's land and water Energy absorption varies depending on the angle of approach, the sea state and the presence of ice or other covering (e.g., foam) Air Temperature - CORRECT ANSWER As solar energy reaches the Earth, equatorial regions heat up more than the poles. Warm air and water at the equator travel poleward while cold air and water at the poles travel equatorward in an attempt to equalize this temperature contrast. It is the atmosphere's continual struggle for temperature balance that brings us our changing weather. Heat budget - CORRECT ANSWER Energy imbalance - more energy comes in at the equator than at the poles 51% of the short-wave radiation (light) striking land is converted to longer-wave radiation (heat) and transferred into the atmosphere by conduction, radiation and evaporation.
Eventually, atmosphere, land and ocean radiate heat back to space as long-wave radiation (heat) Input and outflow of heat comprise the earth's heat budget Latitude - CORRECT ANSWER the distance from the Earth's equator contributes to unequal heating of the Earth's surface. The farther from the equator a location is the less sunlight it receives and thus less heat Conduction - CORRECT ANSWER As one molecule is heated it begins to move and shake rapidly. As it does so, it passes some of its heat energy to other molecules around it. Convection - CORRECT ANSWER Convection takes place when heated molecules move from one place to another, taking the heat with them. Common in both the atmosphere, as well as in the oceans. Heated air in our atmosphere expands, becoming less dense and rises upward. Cooler air rushes in to replace the air that lifted up. As warm air rises, and cool are falls, a giant circular pattern is created. Eventually the warmer air cools, and begins to fall again. Air Pressure - CORRECT ANSWER air pressure is caused by the weight of the air pressing down on the Earth, the ocean and on the air below the pressure depends on the amount of air above the measuring point and falls as you go higher air pressure changes with weather Lithosphere - CORRECT ANSWER the solid part of the earth consisting of the crust and outer mantle Fault - CORRECT ANSWER (geology) a crack in the earth's crust resulting from the displacement of one side with respect to the other
Ocean trench - CORRECT ANSWER deep valley in the ocean floor that forms along a subduction zone Convergent boundary - CORRECT ANSWER A tectonic plate boundary where two plates collide, come together, or crash into each other. Divergent boundary - CORRECT ANSWER the boundary between two tectonic plates that are moving away from each other Transform boundary - CORRECT ANSWER a boundary in which two plates slide past each other without creating or destroying lithosphere Epicenter - CORRECT ANSWER the point on the Earth's surface directly above the focus of an earthquake Focus - CORRECT ANSWER The point beneath Earth's surface where rock breaks under stress and causes an earthquake green revolution - CORRECT ANSWER the introduction of pesticides and high-yield grains and better management during the 1960s and 1970s which greatly increased agricultural productivity overgrazing - CORRECT ANSWER Destruction of vegetation caused by too many grazing animals consuming the plants in a particular area so they cannot recover crop rotation - CORRECT ANSWER The practice of rotating use of different fields from crop to crop each year, to avoid exhausting the soil.
