1. The Sun and Us The Sun’s Energy

2. Energy leaves the sun in the form of heat and electromagnetic radiation Result from the fusion reactions in the sun

3. The Sun’s Energy Fission – splitting of atoms (nuclear bombs) Fusion – fusing of nuclei to form heavier elements (hydrogen to helium) IMMENSE amts. of energy and neutrons released

4. The Sun’s Energy

5. Sun’s Energy In form of Electromagnetic Energy Waves Energy absorbed or radiated by particles Include x-rays, gamma rays, visible light, etc Lots of it may be harmful to life

6. Sun’s Energy Lots of harmful radiation absorbed or reflected by atmosphere Earth’s magnetism also reflects radiation

7. Solar Energy Some radiation gets through Visible light spectrum

9. Sun’s Energy Solar energy that reaches Earth’s surface is… Turned into chemical energy by process called photosynthesis Leads to our own energy

10. Earth’s Energy Solar energy that reaches Earth’s surface is… Reflected/absorbed by land and water Takes LOTS of energy to heat up water Why do you think this is important?
