1. What is the only moon phase in which a lunar eclipse can occur? AA. New moon A BB. Full moon B CC. First quarter C

Think about the placement of the Sun, Earth and Moon…remember lunar begins with L and a lunar eclipse aligns from largest planet to smallest

You are correct !

Think about the placement of the Sun, Earth and Moon…remember that this would make a 90 angle and not a 180 angle that is needed for an eclipse to occur.

2. Why don’t we see a lunar eclipse every 29.5 days? AA. the moon’s orbit is above the plane of the Earths’ orbit A BB. the moon’s orbit is below the plane of the Earth’s orbit B CC. the moon’s orbit is above and below the plane of the Earth’s orbit C

You are half correct-The Moon sometimes travels above the Earth’s orbit

You are half right the Moon sometimes travels below the Earth’s orbit

Great job! You are correct!!!!!

Great job! You are correct!!!

A partial eclipse is easily seen A partial eclipse is easily seen

A total eclipse is the most easily seen eclipse

5.Which type of lunar eclipse has the entire Moon passing through the Earth’s umbral shadow? AA. Total Eclipse A BB. Partial Lunar Eclipse B CC. Penumbral Lunar Eclipse C

Great job! You are correct!!!!!

A partial eclipse passes through the penumbra

It only passes through the penumbra It only passes through the penumbra

6. The alignment of the Sun, Moon and Earth is in what type of angle ? and Earth is in what type of angle ? AA. 90 degree angle A BB. 45 degree angle B CC. 180 degree angle C

A 90 degree angle of Sun, Moon, and Earth is called a First and Third Quarter. An lunar eclipse can only occur in a full moon. A 90 degree angle of Sun, Moon, and Earth is called a First and Third Quarter. An lunar eclipse can only occur in a full moon.

A 45 degree angle occurs in the waning and waxing Crescent or Gibbous phase not in a Full Moon phase A 45 degree angle occurs in the waning and waxing Crescent or Gibbous phase not in a Full Moon phase

Great job!Great job! You are correct!!!!! You are correct!!!!!

The color/darkness of a lunar eclipse varies because- AA. of the amount of dust in the Earth’s atmosphere A BB. of the amount of water in the Earth’s atmosphere B CC. of the distance the Moon is from the Sun C

Great job! You are correct!!!!! Great job! You are correct!!!!!

Water has nothing to do with the color of an eclipse Water has nothing to do with the color of an eclipse
