Which of the following are a consequence of the Earth's yearly motion around the Sun? (check all that apply)
1.the Sun appears in different constellations in different seasons
2.the planets look different than stars
3.the Sun rises and sets
4.the Moon exhibits phases
5.different stars are seen at night in different seasons
6.the Sun changes its height in the sky in different seasons
To determine which of the statements are consequences of the Earth's yearly motion around the Sun, we need to understand the effects of this motion on various celestial phenomena.
1. The Sun appears in different constellations in different seasons: This statement is true. As the Earth orbits the Sun, its position in the sky changes relative to the background of stars. This causes the Sun to appear in different constellations throughout the year. If you observe the night sky consistently, you will notice that different constellations appear at different times of the year.
2. The planets look different than stars: This statement is true, but it is not solely a consequence of the Earth's yearly motion around the Sun. The planets have a different appearance compared to stars because they are much closer to Earth. While the Earth's motion affects the positions of the planets in the night sky, it does not directly cause them to look different.
3. The Sun rises and sets: This statement is true. The Earth's rotation on its axis causes the Sun to appear to rise in the east and set in the west every day. However, this motion is not solely a consequence of the Earth's yearly motion around the Sun but is primarily due to the Earth's rotation on its axis.
4. The Moon exhibits phases: This statement is true. The lunar phases occur as a result of the relative positions of the Sun, Earth, and Moon. As the Earth orbits the Sun, the illuminated portion of the Moon that we see from Earth changes, leading to the different phases (new moon, crescent, half moon, etc.). Thus, this is a direct consequence of the Earth's motion around the Sun.
5. Different stars are seen at night in different seasons: This statement is true. As the Earth orbits the Sun, the view of the night sky changes throughout the year. Different constellations and stars are visible at different times, depending on one's location and the season. This phenomenon is caused by the Earth's orbit around the Sun.
6. The Sun changes its height in the sky in different seasons: This statement is true. The Earth's tilt on its axis causes the Sun's path across the sky to vary throughout the year. This change in the Sun's path leads to differences in its height in the sky at different times of the year, resulting in the change of seasons.
