Textbook Question
Chapter S1, Problem 52EAP
Northern Chauvinism. Why is the writing on maps and globes usually oriented so that the Northern Hemisphere is at the top, even though there is no up or down in space? How does this relate to the fact that the June solstice has traditionally been called the summer solstice? Discuss.

You are lost at Sea – congratulations! Notice, however, that the Sun rises to an altitude of 40° in the South at noon. For some reason your watch is set to UT and reads 18:00. Oh, and it’s the fall equinox… convenient!
Your latitude is…
a.
0°
b.
50° N
c.
40° N
d.

14. Cause of the Seasons. Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly.

- When Earth’s Northern Hemisphere is tilted toward the Sun during June, some would argue that the cause of our seasons is that the Northern Hemisphere is physically closer to the Sun than the Southern Hemisphere, and this is the primary reason the Northern Hemisphere is warmer. What argument or line of evidence could contradict this idea?arrow_forwardWhat is the latitude of the North Pole? The South Pole? Why does longitude have no meaning at the North and South Poles?arrow_forwardIn a part of Earth’s orbit where Earth is moving faster than usual around the Sun, would the length of the solar day change? If so, how? Explain.arrow_forward
- When you step from the shade into the sunlight, the Sun’s heat is as evident as the heat from hot coals in a fireplace in an otherwise cold room. You feel the Sun’s heat not because of its high temperature (higher temperatures can be found in some welder’s torches), but because the Sun is big. Which do you estimate is larger, the Sun’s radius or the distance between the Moon and Earth? Check your answer in the list of physical data on the inside back cover. Do you find your answer surprising?arrow_forwardA 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 Floridaarrow_forwardIn astronomy, what is meant by "local noon"? in other words, where is the sun at "local noon"?arrow_forward
- You are at the Tropic of Capricorn(23.5 degrees Southlatitude), on the summer solstice at mid-day when the Sun is highest in the sky. A) What is the altitude of the Sun at this time in degrees? B) Describe the length of the shadow of a tall flagpole at this time and date? C) Melbourne is at latitude 28 degrees North. Will there ever be a day when the flagpole’s shadow disappears? Briefly justify your answers.arrow_forwardUse four decimal places in your answers please and make it clear.arrow_forwardBased 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_forward
