Based on what you've learn on the impact of the Earth-Sun distance on the seasons, what can you say about the the cause of the seasons? (Give ALL correct answers, i.e., B, AC, BCD...)A) Earth's axis is tilted an an angle of 23.5 degrees compared to a line perpendicular (straight up and down) to its orbit, which is the main cause for the seasons.B) Earth's speed varies in its orbit around the Sun, giving us summer when Earth is moving fastest and winter when Earth is moving slowest.C) The Earth-Sun distance play a major role in creating seasons on Earth.D) The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the southern hemisphere in summer, and vice versa in winter. E) The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year.F) Earth's Northern Hemisphere is always tilted away from the Sun at an angle of 23.5 degrees.G) Earth's Northern Hemisphere is always tilted toward the Sun…
What is declination? Discuss the degree of declination of the Moon and Sun relative to Earth’s equator. What are the effects of declination of the Moon and Sun on the tides?
A graduate student in geology who grew up in Florida (in the southern most tip of the United States) gets to accompany her research professor to the North Pole.
What will be different at the North Pole from the way she remembers the sky in Florida?
1. A celestial pole is overhead
2. The celestial equator is on the horizon
3. The way (and whether) the stars rise and set
4. All of the above would be different as it is in Florida

- Seasons are a result of the inclination of a planet’s axial tilt being inclined from the normal of the planet’s orbital plane. For example, Earth has an axis tilt of 23.4° (Appendix F). Using information about just the inclination alone, which planets might you expect to have seasonal cycles similar to Earth, although different in duration because orbital periods around the Sun are different?arrow_forwardSuppose Earth took exactly 300.0 days to go around the Sun, and everything else (the day, the month) was the same.

- For an entire year, you carefully plot and track the sun's position relative to the background stars (i.e., the celestial sphere). Which of the following is an accurate description of what you observe for the sun's annual drift relative to the celestial sphere? Select one: a. the sun appears to shift only north or south, with no apparent drift east or west b. each day, the sun appears to drift primarily from east to west c. each day, the sun appears to drift primarily from west to east d. the sun does not appear to drift at all relative to the background stars, as defined by our 24 hour dayarrow_forwardThe angle on the sky between Venus and the Sun is measured to be 46.3° when Venus is at greatest eastern elongation.
