The Moon

What is the Moon?

• A large rock that orbits a planet• The Earth has 1 moon

• Moons orbit planets• Planets orbit the sun

Page 3: The Moon. What is the Moon? A large rock that orbits a planet The Earth has 1 moon Moons orbit planets Planets orbit the sun

Moon Facts• The moon is 240,000 miles

from Planet Earth.• The moon rotates

counterclockwise.• There are holes on the

moon’s surface called craters.

• The moon gets its light from the reflection of the sun.

Why doesn’t the moon look the same?

• As the moon orbits around the earth, the light from the sun shines on it.

• From earth, we can only see certain portions of the lit moon.

• It takes 1 month, approx. 29 days, for the moon to completely orbit the Earth.

Animation of the Moon Phases

• Moon Phase Animation• Throughout a month, the moon’s position

changes & we can only see some parts of the illuminated moon.

The Moon Causes Tides

• Tides are caused by the gravitational pull of the moon.

• There are two types of tides: High & Low

• High tide occurs twice a day.

Page 9: The Moon. What is the Moon? A large rock that orbits a planet The Earth has 1 moon Moons orbit planets Planets orbit the sun

The Moon and Tides• Tides are created because the Earth and

the moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon’s gravitational force is able to pull at it.

Diagram of the Moon PhasesThe sun is always shining on the moon.

From earth we can only see certain parts of the moon that are lit by the sun.

Why is a new moon not seen?The reason we don't see any light on the moon during a new moon is because the far side of the moon is getting all the light, while the side we see is cast completely in shadow. When we have a full moon it's because the moon is facing us AND the sun, so we see its light reflected fully. The other phases are the stages in between.

The Phases Build Upon One Another:

Let’s look at the phases all together:

• What does WAXING mean?

• What does WANING mean?

• What is a CRESCENT?

• What is a GIBBOUS?

Karate Kid moon phases

• Another way to identify phases when you look up in the sky:

• Light on the Right=Returning (waxing)• Light on the Left=Leaving (waning)

EclipsesHow do

eclipses occur?

• Revolution of the moon causes them

• Occur when earth or moon temporarily block the sunlight from reaching the other

Page 27: The Moon. What is the Moon? A large rock that orbits a planet The Earth has 1 moon Moons orbit planets Planets orbit the sun

Eclipses can occur only when the sun, moon and earth are perfectly lined up.

When can eclipses occur?

Igneous rocks of the maria are thought

to be 3-4 billion years old (youngest

rocks found on moon surface).

How was the moon formed?

Page 34: The Moon. What is the Moon? A large rock that orbits a planet The Earth has 1 moon Moons orbit planets Planets orbit the sun

Apollo missions led many scientists to support the

impact theory

- Moon was formed 4.6 billion years ago when a Mars-sized object

collided with earth. Gas and debris was thrown into orbit then

condensed into a single mass, forming the moon.

Another science law…

• Kepler’s 3 laws of motion are mathematical explanations of how planets and other bodies in the solar system move.
