The different shapes of the moon that you see from Earth as called ____________.

Phases are caused by the motions of the _______ around the _______.

When you look up at the moon, you may see what looks like a face. Explain this:

The same side of the moon, the "_______" side always faces Earth.

The "________ side" of the mooon, always faces away from earth.

The reason we always see the same side of the moon is explained by the moon's _____________.

Like Earth, the moon moves trough space in two ways.

The moon rotates once on its axis in the same time that it takes to revolve ________ around ____________.

A day on the moon is the same length as a day on Earth.

Since a day is the same length on Earth and the moon, and the moon revolves around Earth, we see the same side of the moon always facing the Earth.

The changing ______________ positions of the moon, Earth and the sun cause the phases of the moon.

_________ the moon is almost always in sunlight.

As the moon orbits the Earth, you see the moon from different angles. The phase of the moon you see depends on how much of the ________ side of the moon faces Earth.

During the new moon phase, the side of the moon facing earth is _______.

As the moon revolves around Eath, you see more of the ___ ise of the moon until you se all of the ______ side.

As the month continues you see less of the lit side of the moon.

About _______ days after the last moon, a new moon occurs again.

As the moon revolves around Earth, the amount of the moon's surface that is lit remains the same.

The part of the lit surface that we see from Earth never changes.

The moon's orbit around Earth is slightly _____ with respect to Earth's orbit around the sun. As a result, the moon travels above and below Earth's orbit. But on rare occasions, Earth, the moon, and the sun line up.

When an object in space comes between the sun and a third object, it casts a shadow on that object, causing an __________.

There are two types of eclipse:

During a new moon, the moon lies between Earth and the ______.

A ______ eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth. The moon's shadow hits the Earth.

The very darkest part of the mooon's shadow is called the __________.

Within the umbra, the sun's light is completely blocked. Only people within the umbra can experience the total solar eclipse.

During a total solar elcipse, the sky grows as dark as night. The air gets cool and the sky becomes an eerie color.

During a solar eclipse, you can see the stars and solar ______, which is the faint outer atmosphere of the sun.

The moon casts another part of its shadow that is less dark than the umbra. This larger part of the shadow is called the ________ where part of the sun is visible from Earth. During a solar eclipse, people in the ________ see only a part of the eclipse.

During most months, the moon moves near Earth's shadow but not quite into it. A _______ eclipse occurs at a full moon when Earth is directly between the moon and the sun.

During a lunar eclipse, Earth _____ sunlight from reaching the mooon. Lunar eclipsese occur only when there is a full moon because the moon is closest to Earth's shadow at that time.

Like the moon's shadow in a solar eclipse, Earth's shadow has an ________ and a ____________.

When the moon is in Earth's _________, you see a total lunar eclipse that can be seen anywhere on Earth that the moon is visible.

You are more likely to see a total lunar eclipse than a total solar eclipse.

A(n) _________ occurs when the moon's shadow hits Earth or Earth's shadow hits the moon.

A person standing in the moon's ____________ would see a partial solar eclipse.

A person standing in the moon's __________ would see a total solar eclipse.

The ____________ of the moon you see depends on how much of the sunlit side of the moon faces Earth.

A(n) ________ eclipse occurs at a full moon when Earth is directly between the moon and the sun.

A(n) _________ occurs when the moon passes between Earth and the sun.

A solar eclipse occurs when the moon

When Earth is directly between the moon and the sun,

As the moon moves through Earth's shadow,

Like Earth, the moon rotates and

Crescents are the different shapes of the mon you see from Earth.

The moon revolves around Earth and revolves on its own axis.

One "day" on the moon is the same length as one month on Earth.

As the moon orbits Earth, the absolute positions of the moon, Earth , and the sun change.

The moon's orbit around Earth is absolutely straight with respect to Earths orbit around the sun.

The amount of the moon's surface that is lit by the sun changes.

During which phases of the moon are the moon, Earth and sun aligned?

The lunar year is how many days long?
