10.1  The Eclipse of the Moon and the Eclipse of the Sun Phenomena
 
Eclipses occur due to several characteristics of light
  • Light travels in a straight line
  • Light cannot penetrate opaque objects
 

2 types of earth and moon shadows:

  1. Umbra area (totally block from sunlight)
  2. Penumbra area (partially blocked from sunlight)

Eclipse of the Sun

  • Eclipse of the sun occurs when the moon is between the sun and the earth
