Unit 1 Test Review

The diagram shows the relationship of the Sun and Earth if Earth’s axis were at a 90° angle relative to its orbit.

How would seasons on Earth differ in this alignment compared to the actual alignment?

• Current seasons on Earth would not be affected.

• No point on Earth would experience a change in seasons.

• The entire planet would experience the same season at all times.

• Seasons would switch every six months instead of every three months.

The figure shows the path of a planet orbiting the Sun. The three areas shaded in gray have equal areas.

According to Kepler’s second law, which conclusion is supported by the data?

• The time intervals from A to B, C to D, and E to F are all equal.

• The time interval from A to B is twice the interval from E to F.

• The distance intervals from A to B, C to D, and E to F combine to be equal to one half of a full orbit.

• The distance intervals from C to D and from E to F combine to be equal to the time interval from A to B.

Some constellations are more prominent in the night sky of North Carolina in winter, while other constellations are more prominent in the night sky in summer. Which best explains why this occurs?Some constellations are more prominent in the night sky of North Carolina in winter, while other constellations are more prominent in the night sky in summer. Which best explains why this occurs?

• because of Earth’s rotation on its axis

• because of stars revolving around Earth

• because of Earth revolving around the sun

• because of the change in the barycenter of Earth
