Questions and Answers
Describe the difference between radiation, conduction, and convection.
Radiation transfers through space in the form of visible light, conduction transfers through collisions of the atoms and molecules of a substance, and convection transfers through the motion of the liquid or gas caused by difference in density.
Explain the meaning of insolation.
Insolation is energy from the sun that reaches Earth.

Study Notes
Heat Transfer Mechanisms
- Radiation: Transfers heat through space as visible light.
- Conduction: Transfers heat via collisions between atoms and molecules.
- Convection: Transfers heat through the movement of liquids or gases caused by density differences.
Insolation and Seasonal Temperature
- Insolation: Refers to solar energy reaching the Earth.
- Hottest Time in Northern Hemisphere: June 21 marks maximum insolation, resulting in peak summer temperatures.
Air Pollution Reduction Technologies
- Clean Air Act of 1970: Establishes methods for modern pollution control in power plants and factories to mitigate air pollution.
Atmospheric Composition
- Gases: Includes nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
- Abundant Gas: Nitrogen is the most prevalent gas in the atmosphere.
Atmospheric Layers
- Troposphere: The lowest layer, with decreasing temperature as altitude increases.
- Stratosphere: Clear and dry layer above the tropopause.
- Mesosphere: Temperature decreases with altitude; situated above the stratosphere.
- Thermosphere: Layer above the mesosphere, where temperature rises with altitude.
- Ionosphere: Part of the thermosphere where ionization occurs due to solar radiation.
Ozone
- Ozone Molecule: Composed of three oxygen atoms, important for blocking harmful UV radiation.
Isotherms
- Definition: Lines that connect locations with identical temperatures.
Temperature Inversion
- Description: Phenomenon where temperature increases with altitude, occurring when a cold air layer is trapped beneath warmer air.
