Michael learned that the movement of Earth in the solar system causes changes

that can be seen on the planet. Which change could be seen on Earth in the time it takes Earth to rotate once on its axis?

• Day becoming night

• January changing to February

• Winter changing to Spring

• A New moon becoming a Full Moon

Answer explanation

One rotation = only 24 hours! So it happens daily. Day becomes night daily!

A student is going to walk outside to observe her shadow at four different times during a day. At which time will the student most likely notice her shadow is the

shortest?

• 12:05 in the afternoon

• 8:05 in the morning

• 4:05 in the afternoon

• 7:05 in the evening

Answer explanation

Sunrise and sunset will produce the longest shadows of the day, because that’s the most extreme angle possible before the horizon blocks the sun. Noon is going to produce the shortest shadow of the day because it's the furthest time away from sunrise and sunset.

This is an illustration of a waxing moon. What causes the moon to appear this way?

• light from the sun is being reflected on part of the Moon

• light produced by the Moon is being reflected by the Earth

• the moon is moving away from the shadows of Earth

• the Moon is moving into the shadow of Earth

Answer explanation

The light is not produced by the Moon! The Moon itself is rotating and causing light to only be reflected on a small part of the Moon.

Which natural event occurs with the most frequency (the most times)?

• sunrise

• equinox

Sunrise and Sunset both happen each day as the sun rises and then sets. The other choices occur less frequently.

Which term describes the path the Moon travels around Earth?

• Orbit

• Rotation

• Day

• Phase

Answer explanation

The Moon is rotating on its own axis while revolving/orbiting around the Earth. You can think of this like the Earth and the Sun- the Earth is rotating on its own axis while also revolving around the sun.

How often does the cycle shown in the diagram occur?

• Hourly

• Daily

• Weekly

• Monthly

Answer explanation

The sun rising and setting happens every day. It does not happen every hour (too often), every week or month because that's not enough. Could you imagine having sunshine all day for days and then switching to darkness all day for days? Strange!
