1 If Earth’s orbit were a perfect circle, we would not have seasons.
True, because it is the departures from a circular orbit that create the seasons on Earth. False; the seasons are due to the tilt of the Earth’s spin from its orbit, not its distance from the Sun. True; the Earth would be at the same distance from the Sun throughout its orbit, so there would be no summer or winter. False; the poles would still be cooler than the equator and seasonal variations would therefore still exist. :00

2 Mars occasionally undergoes retrograde motion, which is:
When Mars rises towards the West and sets towards the East --- the opposite of what the Sun and stars do When Mars’ position on the sky from night to night moves from the West towards the East Neither of the above :00

3 #1A: Rank the time it took (from greatest to least) for the comet to move along each of the segments (A-D) of the orbit. D C A B B A C D A B C D D C B A Time to travel each segment is the same :00

4 #1B: Rank the distance (from greatest to least) the comet traveled during each of the segments (A-D) of the orbit. D C A B B A C D A B C D D C B A Distance traveled during each segment is the same :00

5 #1C: Rank the speed (from slowest to fastest) of the comet during each segment (A-D) of the orbit.
D C A B B A C D A B C D D C B A Speed of the comet during each of the segments is the same :00

6 Ranking Task #3: Rank the orbital period (from longest to shortest) of the planets.
A=D B=E C C B=E A=D A D B E C C E B D A A D=B E=C C=E D=B A Orbital periods of the planets all the same :00

7 Ranking Task #5: Rank the orbital periods (from longest to shortest) of the planets.
A=B C=D C=D A=B A B D C C D B A B A C D D C A B All the same :00
