1. Chapter 16 : Weather Factors Section1 : Energy in the Atmosphere By : Katelyn Angers

2. Electromagnetic Waves When the sun’s rays come to the earth it comes by Electromagnetic Waves. The Electromagnetic waves are classified by the length and the distance.

4. Radiation The direct transfer of energy is called radiation. Radiation comes from the sun in many different lengths.

5. Infrared radiation Most of the sun’s energy reaches the earth in the earth in the form of visible light, and infrared radiation.

6. Ultraviolet radiation There is also a small amount of ultraviolet radiation. Ultraviolet radiation is when the wavelength is short.

8. Greenhouse effect The atmosphere is like a blanket it keeps the hot air in. That is called greenhouse effect. Even in the winter the greenhouse still stays warm. That is what the atmosphere does. Carbon dioxide in the atmosphere. Which may be warming the atmosphere.

9. Scattering Some of the sun’s rays are reflected and that is called scattering. The light is scattered by gas, or molecules.

10. Guide for reading In what form does energy from the sun travel to the earth? What happens to energy from the sun when it reaches earth?

11. Can you answer these question? List three forms of radiation from the sun. How are they different? What happens to the energy the sun that is absorbed by the Earths surface? Why is the sky blue? Why are sunsets often red? What might conditions on earth be like without the greenhouse effect?
