Textbook Question
Chapter S1, Problem 38EAP
Opposite Rotation. Suppose Earth rotated in a direction opposite to its orbital direction; that is, suppose it rotated clockwise (as seen from above the North Pole) but orbited counterclockwise. Would the solar day still be longer than the sidereal day? Explain.

- 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…arrow_forwardDescribe the shape of Earth's orbit.
