If the angle of the Earth's axial tilt were increased from 23° to 30°, what would
| | | | | | | | | | | | | | | |
change? - CORRECT ANSWER✔✔-The days would be longer in July in Tierra del
| | | | | | | | | | | | |
Fuego, Argentina (latitude 54° S)
| | | |
The size of the Arctic would increase
| | | | | |
The size of the tropics would increase
| | | | | |
Syracuse, NY (latitude 42° M) would experience more extreme winters
| | | | | | | | |
How much of the Moon's total surface (not just the part we can see) is
| | | | | | | | | | | | | | |
illuminated by the Sun during a gibbous moon? - CORRECT ANSWER✔✔-Half of it
| | | | | | | | | | | |
Which statement correctly describes the motion of the stars in the sky each
| | | | | | | | | | | | |
night? - CORRECT ANSWER✔✔-All of the stars are different distances from us, but
| | | | | | | | | | | |
|all appear to move together in the same way. This is because they are very far
| | | | | | | | | | | | | | | |
from Earth, much further away than the distance we move in a year, and their
| | | | | | | | | | | | | | |
apparent motion is only because of our own rotation.
| | | | | | | |
If you are standing exactly on the Arctic Circle, you will experience exactly one
| | | | | | | | | | | | | |
day of polar night each year-- a day when the Sun does not rise above the horizon
| | | | | | | | | | | | | | | |
|at all. This day is: - CORRECT ANSWER✔✔-The June solstice
| | | | | | | | |
, Which of the following gives the correct ranking of the distances of the following
| | | | | | | | | | | | | |
objects from Earth, from closest to furthest away? - CORRECT ANSWER✔✔-
| | | | | | | | | |
Moon; Sun; Saturn; Polaris; the center of the Milky Way
| | | | | | | | |
You point your left arm North, and point your arm directly at the North Star. What
| | | | | | | | | | | | | | |
is they angle between your two arms?
| | | | | | |
Syracuse is located at 42° N latitude. The axial tilt of the Earth is about 23°. -
| | | | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-42 degrees | |
You are traveling through the desert. Since it is so hot during the daytime, you
| | | | | | | | | | | | | | |
would prefer to camp during the day an travel at night. However, it is too dark to
| | | | | | | | | | | | | | | | |
travel when the Moon is not visible. Thus, you can only travel when the Moon is
| | | | | | | | | | | | | | | |
visible, but the Sun is not.
| | | | |
Suppose that the phase of the moon is third quarter- that is, a waning half moon.
| | | | | | | | | | | | | | | |
Approximately what times will you be able to travel tonight? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-From midnight until 6am | | |
Suppose that the Earth did not revolve around the Sun, but simply stayed in one
| | | | | | | | | | | | | | |
place and rotated on its axis. Which of the following would happen? - CORRECT
| | | | | | | | | | | | | |
ANSWER✔✔-The solar and sidereal days would be the same length. | | | | | | | | |
Which place experiences greater variability between the seasons? - CORRECT
| | | | | | | | | |
ANSWER✔✔-Nunavut, Canada (latitude 63° N) | | | |
