• Never bright

• Sometimes bright

• Usually dark

• Always bright

What is the primary reason why we only see one side of the moon from Earth?

• The moon rotates on its axis at the same rate it orbits Earth.

• The moon's gravitational force causes it to always face away from Earth.

• The moon has a highly reflective surface that only reflects light towards one direction.

• Earth's atmosphere blocks our view of the other side of the moon.

What phase of the Moon is letter C?

• Waxing Gibbous

• First Quarter

• Third Quarter

• There could be a lunar eclipse when the Moon is at point A.

• There could be a new moon when the Moon is at point A.

Our universe is full of movement controlled by gravity. All planets in our solar system are held in orbit by the Sun's strong gravitational pull. Many phenomena involving Earth are caused by its relationships with the Sun and moon. Think about the connections and movement patterns of the Sun, Earth, and the moon. Which four statements are true about the phenomena that occur between the Sun, Earth, and moon?

• On Earth, one day is the time it takes Earth to orbit the Sun one time.

• The time it takes Earth to revolve once around the Sun is one year.

• Tides are caused by the gravitational pulls between the Earth and the Sun.

• A lunar eclipse occurs when a full moon passes directly behind Earth and is covered in Earth’s shadow.

• The position of the Moon in relation to the Earth and Sun at a given moment determines its phase.

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

• behind the Sun and the Moon.

• in front of the Sun and the Moon.

• in between the Sun and the Moon.

• next to the Sun but not the Moon.
