1. Phases – different shapes of the moon you see from Earth.
Phases, Eclipses, and Tides
  Phases – different shapes of the moon you see from Earth. A C B E D H F I G

2. Eclipse – an object in space comes between the sun and a third object and it casts a shadow on that object. Solar Eclipse – when the moon blocks the view of the sun.
Umbra – very darkest part of the moon’s shadow
Penumbra – larger part of the shadow that is less dark

3. Lunar Eclipse – occurs during a full moon when the Earth is directly between the moon and the sun

4. Tides – rise and fall of ocean water caused by differences in how much the moon’s gravity pulls on different parts of Earth
Spring – force produces a tide with the greatest difference between low and high tides – during a full and new moon
Neap – tide with least difference between low and high tides – during the first and third quarter moon

5. Earth’s Moon The surface has many different features, including:
Maria – dark, flat areas made from hardened rock from huge lava flows
Craters – large round pits caused by the impacts of meteoroids
Highlands – rugged moon surface, lighter in color
Statistics: The moon is very dry and airless, it has no liquid water It is small compared to earth – 3476 km It has a large variation in surface temperature throughout the day – 130oC to -180oC Thought to exist because of the collision theory and that it was once part of Earth
