The phase of the Moon you see depends on

• where you are on Earth’s surface.

• how much of the sunlit side of the Moon is visible from Earth.

• how much of the Moon’s surface is lit by the Sun.

• whether or not an eclipse is occurring.

From new Moon phase to full Moon phase, you see

• An increasing amount of the lighted side of the Moon.

• B. a decreasing amount of the lighted side of the Moon.

• C. the same amount of the lighted side of the Moon

• D. more of the lighted side, then less of the lighted side of the Moon.

For a solar eclipse to occur,

• A. the Sun must be directly between the Earth and the Moon.

• B. the Moon must be directly between the Earth and the Sun.

• C. the Moon must be directly behind Earth.

• D. Earth must be directly between the Sun and the Moon.

Why don’t we experience eclipses every lunar cycle?

• Eclipses can only happen during June and December

• Eclipses can only happen during April and November

• The moon’s orbit is offset at a 5° angle relative to Earth’s orbit, so the Moon isn’t always in the same orbital plane as the Sun and Earth.

• The Moon’s tilted axis pulls the Moon closer and farther from Earth, so the moon isn’t always in the same orbital plane as the Sun and Earth.

You are less likely to see a total solar eclipse than a total lunar eclipse because the Moon’s umbra only covers a small area on Earth’s surface.
