EM: Energy Budget
Energy in the Atmopshere & Earth's Energy Budget
Question | Answer |
---|---|
How many types of EM radiation come from the Sun | 7 |
Which three types of radiation make it through Earth's atmopshere | Inrared, Ultraviolt, Visible light |
Amount of total radiation reflected back into space | 30% |
UV | Harmful high energy radiation |
Amount of total energy absrbed by Earth's surface | 51% |
Infrared | Radiation you cannot see but feel as heat |
Earth Energy Budget | Describes the balanced amount of solar energy absorbed and reflected by Earth |
Visible light | radiation we can see with the naked eye (Roy. G. Biv) |
Which of the following does NOT rely on solar radiation? a). Geothermal (Earth's internal heat) b) Wind (the movement of the atmopshere) d) Fossil Fuels (created through photosynthesis e) Hydroelectric (created through the water cycle) | a) Geothermal (Earth's creates it's own internal heat |
to Absorb | to take in or soak up |
to Reflect | to reject |
to Scatter | to spread in many directions |
Why is the sky blue | Earth's atmosphere scatters blue light the best |
Atmosphere | gases that surround a planet |
the Greenhouse Effect | the process where certain gases "trap" heat in Earth's atmosphere |
All the Greenhouse Gases | Carbon Dioxide, Methane, Water Vapor, etc..These gases trap heat from the Sun in Earth's atmopshere |
What would happen to Earth if greenhouse gas levels rose? | Possible Answers: 1. Global Temps would increase 2. Polar ice caps & glaciers would melt |
How are human contributing to the Greehouse House Effect? | Burning fossil fuels which increase CO2 (carbon dioxide) in the air;a greenhouse gas |
CO2 | Carbon Dioxide |
Energy transfer from the formation of coal to how we get electricity in a coal power plant | radiant--chemical--thermal--mechanical---electrical |
Things that reduce greenhouse gases such as CO2 in the atmosphere | Plants; Earth's oceans |
