Vocab
Entire face is illuminated; Earth is between the Sun and Moon.
Full Moon
True or Flase: The Moon is always out at night.
False
More than half lit, still growing. Right side lit.
Waxing Gibbous
an angle of the moon to the earth so it appears differently every day
Phase
Left half of the Moon is lit.
Last (Third) Quarter
Moon blocks sunlight from reaching Earth.
Solar Eclipse
Earth blocks sunlight from reaching the Moon.
Lunar Eclipse
How long is the moon cycle
28-29.5 days
A sliver of light appears on the right side; “waxing” means growing.
Waxing Crescent
The penumbra can be seen as the partially shaded area surrounding the umbra.
Penumbra
Only a sliver remains on the left; shrinking to new moon again.
Waning Crescent
The Moon is between Earth and the Sun; the side facing Earth is not lit.
New Moon
Light begins shrinking from the right; “waning” means decreasing.
Waning Gibbous
A lighter shadow surrounded by a darker region, observed during certain conditions like solar eclipses.
Antumbra
Right half of the Moon is lit; Moon is ¼ of its way around Earth.
First Quarter
The darkest part of a shadow where the light source is completely blocked.
Umbra
the Earth completely blocks the sunlight from reaching the moon. The moon appears reddish or orange because some sunlight passes through Earth's atmosphere and gets bent.
Total Lunar Eclipse
only a part of the moon moves through Earth's shadow, so it appears partially darkened.
Partial Lunar Eclipse
the moon passes through the Earth's outer shadow called the penumbra. This type of eclipse is subtle, and the moon may appear slightly dimmer.
Penumbral Lunar Eclipse
Why we only see one side of the Moon.
Synchronous Rotation
Does the moon change shape? If yes why if no why?
No we only see certain amount lit up per time.
the moon blocks only a part of the sun, creating a crescent shape. This happens when the observer is not in the path of totality but still sees a portion of the sun covered by the moon.
Partial Solar Eclipse
True or False: The moon produces its own light
False
the moon completely covers the sun, and the sky becomes dark. People in the path of totality, where the moon's shadow falls, can see the sun's outer atmosphere, called the corona.
Total Solar Eclipse
occurs when the moon is farther from the Earth and appears smaller. During this eclipse, the moon doesn't fully cover the sun, leaving a ring of sunlight visible around its edges.
