Eclipses Study Pack #8

Today’s Goals!  I can explain what causes an eclipse. I can compare solar and lunar eclipses.

Eclipses The sun, moon, and Earth do not usually line up in a straight line If this occurs a shadow can fall on the moon or Earth Most months the moon revolves around Earth without moving into Earth’s shadow or the moon’s shadow hitting Earth

Eclipses When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs There are two types of eclipses Solar “sun” Lunar “moon”

Solar Eclipses Happens during a new moon The moon passes between the sun and Earth The moon’s shadow hits Earth

Solar Eclipse The darkest part of the moon’s shadow is called the umbra From this point the sun is completely blocked by the moon People on Earth experience total solar eclipse The sky is dark and you can see the stars!

Total Solar Eclipse

Solar Eclipse The larger part of the moon’s shadow that is less dark is the penumbra People on Earth see a partial solar eclipse It’s never safe to look directly at a solar eclipse!

Lunar Eclipse Occurs at a full moon The Earth is directly between the sun and moon The Earth blocks sunlight from reaching the moon
