Greenhouse Effect

Storyboard Text

  • Albedo is the measure of the reflection of incoming solar radiation.
  • Clouds have a high Albedo and incoming solar radiation passes right through it.
  • Ice has a high Albedo and when solar radiation its its surface it bounces back up .
  • The ozone layer absorbs most of the harmful ultraviolet radiation from the sun.
  • Pavement has a low Albedo on earth's surface.
  • Ozone Layer
  • The frequency of solar radiation is higher than earth's radiation but the wavelengths are shorter than earth's radiation.
  • Solar Radiation that reaches earth's surface is mostly made up of infrared light. Radiation that gets emitted by earth's surface is visible light.
  • Solar Radiation
  • Earth's Radiation
  • When radiation emitted by earth's surface comes in contact with greenhouse gases it gets absorbed then bounced into random directions.
  • The outgoing radiation emitted by earth's surface bounces back into the atmosphere.
  • This effects earth average temperature because if there are not greenhouse gases then we freeze and if there are to many we overheat so there need to be a perfect amount.
  • Nitrous Oxide
  • Carbon Dioxide
  • Burning fossil fuels has increased the amount of Carbon Dioxide in the atmosphere.
  • Nitrous oxide
  • Human activity has increased the amount of nitrous oxide in the atmosphere because activities such as agriculture, waste management and industrial process are becoming more popular so we require more nitrous oxide so more is being released into the atmosphere.
  • Carbon Dioxide
  • Human activity has increased methane concentrations in the atmosphere because we mid coal, leaks in natural gas and the rise of livestock.
  • Coal
  • Methane going up into atmosphere.
  • A. Around every 100,000 years there is a peak in Carbon Dioxide levels.B. The concentration of carbon dioxide in the atmosphere never exceeds 300 (ppm) in the last 800,000 years.C. Today's Carbon Dioxide levels are much higher than 800,000 years ago because we use more fossil fuels which require more energy which is why the concentration levels are higher.D. The change in Carbon Dioxide levels effects the outgoing radiation emitted because the radiation has a higher chance of bouncing off a greenhouse gas rather than going in a different direction if the levels are high. E. The infrared radiation wants to bounce up in the atmosphere but when the levels of Carbon Dioxide are high it is much harder and more infrared radiation gets trapped down on earth.
