Study Notes
Earth Science Chapter 11, Section 1
- Atmosphere composition is mainly nitrogen (78%) and oxygen (21%), with trace amounts of other gases
- Argon comprises 0.93%
- Carbon dioxide takes up 0.038%
- Water vapor varies from 0.0% to 4% depending on factors like altitude and season
- Concentrations of some gases like carbon dioxide fluctuate over time
- Carbon dioxide concentration increased significantly during the industrial era, primarily due to fossil fuel burning
- Ozone layer is crucial for shielding Earth from harmful ultraviolet (UV) rays; it's formed by the addition of an oxygen atom to an oxygen molecule
- Atmospheric particles, such as dust, salt, and ice, are also in the atmosphere
- The atmosphere has five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere
Energy Transfer in the Atmosphere
- Radiation: Transfer of thermal energy through electromagnetic waves, from the sun to Earth. Incoming solar radiation reflects, absorbs into the atmosphere or is absorbed by Earth's surface
- Conduction: Transfer of thermal energy through direct contact between molecules. Heat transfer from the ground heating the air.
- Convection: Transfer of thermal energy through the movement of heated material; warm air rising, cool air sinking.
