The Moon Kim Lachler Updated 2014 NCES: 6.E.1.1

A moon Orbits a planet Is smaller than the planet

Earth’s moon Earth has one moon ¼ the size of earth 385250 km from earth it has no atmosphere temperatures ranging from -163˚ C to 123˚ C.

Earth’s moon The light seen from the moon is really a reflection of the suns light. 1 rotation takes the same amount of time as 1 revolution; therefore, we only see 1 side of the moon The side of the moon that is not seen from earth is called the far or dark side.

Moon Phases It takes 28 days for the moon to revolve around the earth, causing different phases of the moon as we see the suns reflection at different angles.

Moon Phases new Can’t see it The moon is between the sun and the earth.

Moon Phases crescent is curved shape

Moon Phases 1st quarter (half moon) looks like half of it

Moon Phases gibbous see ¾ of it.

Moon Phases full moon see all of it the earth is between the sun and moon

Moon Phases Then it starts back to towards a new moon Gibbous 3rd quarter (half moon) Crescent Back to new

Other moon terms Waxing When the moon is becoming larger. The light is on the right.

Other moon terms Waning The moon is becoming smaller. The light is on the left.

Other moon terms Blue moon More then 1 full moon in a month. How long does it take for the moon to revolve around the earth? How many days are in a month? That’s where the saying once in a blue moon comes from.

Eclipses Solar Eclipse A total solar eclipse requires the Moon's shadow to touch the surface of the earth. The path of the shadow is usually very narrow; therefore, it is only seen by a few areas on earth

Eclipses Lunar Eclipse When the moon passes behind the earth, the earth blocks the sun's rays from striking the moon. Can be seen anywhere on earth.

Tides Tides of the ocean are affected by the gravity of the moon and sun.

Tides Low tide High tide Two high and low tides a day sea level lowest sea level highest Two high and low tides a day

Tides Spring tide The sun and moon pull same direction causing max high and low tides.

Tides Neap tide The sun and moon are at 90 degrees pulling the water in different directions causing a smaller difference in high and low tide.
