Amplify: Patterns of Earth and Sky

Why does the daytime section of the artifact show only the sun in the sky, but not other stars?

• The sun's brightness overwhelms the light from other stars, so that's why we can't see the other stars.

• Stars are not present in the sky during the day.

• The clouds blocks the view of stars during the day.

• The artifact is designed to only show the sun. and not other stars.

Answer explanation

The correct choice explains that the sun's brightness overwhelms the light from other stars, making them invisible during the day. This is why only the sun is visible in the daytime section of the artifact.

How long does it take for Earth to complete one rotation?

• One hour

• One day

• One month

• One year

Answer explanation

Earth takes approximately one day to complete one full rotation on its axis, which is why we experience day and night. The other options, such as one hour, one month, and one year, do not accurately represent this rotation period.

How long would it take for Earth to complete one full orbit around the sun?

• One hour

• One day

• One month

• One year

Answer explanation

Earth takes one year to complete its orbit around the sun. This is due to the gravitational pull of the sun and the distance Earth travels in its elliptical path, making 'one year' the correct answer.

The picture shows the daytime side of Earth. Which of the following best describes why Earth has day and night?

• The Moon's Rotation

• The Earth's Rotation

• The Moon revolves around Earth

• The Earth's Orbit

Answer explanation

Earth has day and night due to its rotation on its axis. As it spins, different parts of the planet face the Sun, creating daytime, while the opposite side experiences night.

Scientists would see Constellation C in the sky on November 2024. When would you be able to see this constellation again?

• Every day of the year.

• Every 6 months.

• On the same day every year.

• Every 3 months

Answer explanation

Constellations appear in the same position in the sky on the same date each year due to Earth's orbit around the Sun. Therefore, if Constellation C is visible in November 2024, it will be visible again in November each subsequent year.
