Presentation Transcript

  1. Eclipses • When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs. • There are 2 types of eclipses: solar (sun) eclipse & lunar (moon) eclipse. • The type of eclipse is named for what is being blocked from Earth. • Total solar eclipse Total lunar eclipse

  2. Solar Eclipse The umbra is the darkest and smallest part of the shadow & is cone shaped (total darkness). The penumbra is the largest part of the shadow (partial darkness). • Total Solar Eclipse: • Only people in the umbra experience a total solar eclipse. • Partial Solar Eclipse: • In the penumbra, people only see a partial eclipse; since part of the sun is still visible, it is not safe to look directly at the eclipse.

  3. Lunar Eclipse • During a full moon the Earth blocks the sun’s light from reaching the moon making the moon look dark from Earth. • Total Lunar Eclipse • When the moon is in the Earth’s umbra, there is a total lunar eclipse • Partial Lunar Eclipse • The moon passes partly into the umbra of the Earth’s shadow.
