System, Star Cluster, Milky Way, Galaxy Cluster
| | | | | |
What causes the seasons? - CORRECT ANSWER✔✔-The tilt of the
| | | | | | | | | |
Earth's rotation axis to its orbit around the Sun causes parts of the Earth
| | | | | | | | | | | | |
to experience more direct illumination from the Sun and longer days
| | | | | | | | | | | |
during the summer than the winter
| | | | |

| | | | | | | | | | | |
planets travel faster when they are closer to the Sun? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-The force of gravity is stronger closer to the Sun. | | | | | | | | |

| | | | | | | | |
resolution images primarily because - CORRECT ANSWER✔✔-
| | | | | |
deformable mirrors are used to correct the blurring due to Earth's
| | | | | | | | | | |
atmosphere
, This is a long exposure image of the North Celestial Pole. What
| | | | | | | | | | | |
information does the elevation of the North Celestial Pole (the height

Light from a far-away 8,000 K star passes through a cloud of cold oxygen
| | | | | | | | | | | | |
gas before reaching Earth. Which of the following best illustrates the

rotation of the Earth. Nothing is drawn to scale, especially not the turtle.
| | | | | | | | | | | |
What is the time of day (approximately) where the turtle is located? -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-6pm (sunset) | |
Astronauts on the International Space Station (ISS) can float while
| | | | | | | | | |
orbiting Earth. Why are astronauts on the ISS weightless? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-They are falling around Earth at the same rate as the ISS. | | | | | | | | | | |
There is a full Moon at Sunset and you are looking directly at the Moon.
| | | | | | | | | | | | | | |
Which direction are you looking? - CORRECT ANSWER✔✔-east
| | | | | | |

| | | | | | | | | | | | | | | |
major axis that is 10 times larger than that of Earth, roughly how long
