2. “Tricky Moon Phase Diagrams”1.

3. 2. Which phase describes the appearance of the Moon at position P when viewed from Earth?
Position P represents the waning crescent moon phase. (D) The position after it is the new moon, so the position before it has to be waning crescent.

4. 3. When viewed from Earth, which phase of the Moon will be seen when the Moon is at point C?
Position C must be the first quarter Moon. (A) Position A happens to be the new moon, Position E is in the full moon so if you know your order, C must be the
FIRST QUARTER

5. 4. Which phase of the Moon will be seen when the Moon is at point E?
Look at where the Sun is coming from. Position A we cannot see the Moon, so it is a NEW moon. Since E is on the opposite side of the new moon, it must be the FULL MOON. (B)

8. Solar Eclipses
During most months, the moon travels a little above or below the suns plane in the sky
During a Solar eclipse the moon blocks light from the sun, preventing the light from reaching the Earth

Solar eclipses can be only be seen along a narrow path in the sky They are NOT safe to watch

9. Solar Eclipses

The sun, moon and earth are specifically lined up during a solar eclipse.

12. Lunar Eclipses
During most months, the moon goes near the Earth’s shadow, but not quite into it
The moon’s orbit is tipped 5° to Earth’s orbit. Most of the time its above or below our orbital plane
Two to four times a year it is on the same plane and an eclipse occurs
Lunar eclipses can be seen anywhere on the night side of the Earth They are safe to watch

13. Lunar Eclipses
The Lunar eclipse occurs during the full moon phase and only if the Moon passes through some portion of the Earth's shadow.
