Which location of the moon relative to the sun and earth may produce a lunar eclipse?

• B

• C

• D

Which location of the moon relative to the sun and earth may produce a solar eclipse?

• A

• B

• C

• D

The temperature on land around the equator stays about the same throughout the year. This is because this area

• A) has a greater tilt than other parts of the Earth.

• B) receives less direct sunlight throughout the year.

• C) receives similar amounts of sunlight throughout the year.

• D) receives more direct sunlight than other parts of the Earth.

As Earth spins on its axis, producing night and day, it also moves about the Sun in an elliptical orbit that requires about 365 1/4 days to complete. The Earth's axis is tilted with respect to its orbital plane. When the earth's axis points towards the sun, it is ________ for that hemisphere.

• A) summer

• B) winter

This diagram shows a lunar eclipse. During a lunar eclipse, the Earth is

• behind the Sun and the Moon.

• in between the Sun and the Moon.

• in front of the Sun and the Moon.

• next to the Sun but not the Moon.

Why are reoccurring solar eclipses so rare?

• Because of the rotation of the moon and earth, the three rarely form a straight line.

• The light from the sun usually passes through the moon instead of being blocked by it.

• A total solar eclipse actually occurs monthly, but is only visible from the equator.

• The Moon passes slightly above or below the line between the Sun and the Earth because of its tilted orbit.

What is the setup in the diagram trying to model?

• The phases of the Moon

• The rotation of the Earth on its axis

• A solar eclipse

• The orbit of the Earth around the Sun

What is depicted in the image provided?

• A lunar eclipse

• A galaxy

• A solar flare

• A solar eclipse

The sun and moon are very different sizes, but often appear to be the same size. During a solar eclipse, our tiny moon can totally block the giant Sun because of

• the dark side of the Moon facing Earth.

• the large shadow Earth casts on the Sun.

• their differing distances from Earth.

• the reflection of light waves from the Sun.

Which of these causes the day/night cycle on Earth?

• Earth’s rotation

• Earth’s polar tilt

• Earth’s revolution around the Sun

• The Moon's orbit around Earth
