Lunar and Solar Eclipse
Moon Phase for Solar Eclipse
New moon
What are the two parts of a shadow?
Penumbra and Umbra
Partial solar eclipse?
The moon, earth and sun don't align perfectly.
Which eclipse lasts longer?
A lunar eclipse would last longer.
Why don't we see a lunar eclipse every time there is a full moon?
A lunar eclipse occurs when the Moon enters the Earth's shadow. A solar eclipse occurs when the Moon's shadow falls on the Earth. They do not happen every month because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
Why don't we see a solar eclipse every time there is a new moon?
A solar eclipse occurs when the Moon's shadow falls on the Earth. They do not happen every month because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
What causes a total solar eclipse to occur?
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.
Is the umbra larger during a lunar and solar eclipse? Why?
A solar eclipses and lunar eclipses only occur every so often because they require the Moon to enter the Earth's umbra. The Earth's umbra is involved in both total and partial lunar eclipses.During a total lunar eclipse, the entire Moon enters the umbra.
What is an annular solar eclipse? Why does it occur? .
An annular solar eclipse happens when the Moon covers the Sun's center, leaving the Sun's visible outer edges to form a "ring of fire" or annulus around the Moon. It happened because the apparent size of the Moon is smaller than that of the Sun
Approximately how many lunar and solar eclipses occur each year?
Any calendar year has a minimum of four eclipses - two solar and two lunar. Most years have only four eclipses, but depending on the year, it's possible to have five eclipses, six eclipses or even as many as seven eclipses in one year's time.
What causes the red color that may be visible during a lunar eclipse?
During a total lunar eclipse, the Earth moves between the Sun and the Moon and cuts off the Moon's light supply. When this happens, the surface of the Moon takes on a reddish glow instead of going completely dark.
Partial lunar eclipse?
Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra.

Are more people able to see a solar or a lunar eclipse? Why?
Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.

Umbra
The Moon's dark inner shadow. Total solar eclipses are visible from within the umbral shadow
Penumbra
The Moon's faint outer shadow. Partial solar eclipses are visible from within the penumbral shadow.
What causes a total lunar eclipse to occur?
When the moon passes directly behind the Earth into its umbra
Eclipse
a period of time when the light from an object in the sky cannot be seen because another object has come between you and it.
