Understanding the Weather Chapter 1 Review Composition of the Atmosphere: Permanent Gases- Nitrogen 78%, Oxygen 21% Variable Gases- Water Vapor, Carbon Dioxide, Methane, Nitrous Oxide, Ozone, Particles, CFCs Processes that add or remove carbon dioxide from the atmosphere: Add- Fuel Combustion, Volcanic Activity, Burning Plants, Respiration, Soil Decay, Deforestation, CO 2 evaporates Remove- Weathering erosion, Photosynthesis, CO 2 Dissolves, Marine Life activity Thermal Layers of the Atmosphere: Troposphere - The region of circulating air extending upward from the earth’s surface to where the air stops becoming colder with height. Tropopause - Its height will be higher in summer and lower in winter. This is where jet streams take place. Stratosphere - The layer of the atmosphere above the troposphere and below the mesosphere, generally characterized by an increase in temperature with height. Stratopause - Marks the end of the Stratosphere and beginning of the mesosphere. Mesosphere - The atmospheric layer between the stratosphere and the thermosphere. Located between 50 and 80 km above earth’s surface and characterized by a decrease in temperature at higher altitudes. Mesopause - The top of the Mesosphere and bottom of the thermosphere. Thermosphere - The atmospheric layer above the mesosphere where the temperature increases rapidly with height. Air Pressure:The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of mercury (Hg), or in hectopascals (hPa). How do Pressure and Density change with altitude?: Pressure becomes less and less as altitude increases, because the most dense air is closest to the surface of the earth. Weather and Climate: Weather is the condition of the atmosphere at any particular time and place, and is always changing. Climate is the average weather of a particular region over an extended period of time. Meteorology: The study of the atmosphere and atmospheric phenomena as well as the atmosphere’s
