Answer:
1. A (northern hemisphere turned towards the sun)
2. C (northern hemisphere turned away from sun)
3. C (southern hemisphere turned towards the sun)
4. A (southern hemisphere turned away from sun)
5. Picture D shows Earth's Northern hemisphere in spring time because the seasons go in order of Summer (A), Fall (B), Winter (C), and Spring (D), and since Spring comes after Winter, D would be springtime in the Northern Hemisphere.
6. Since D is spring for the northern hemisphere, B would be Fall because they are opposite seasons, and B and D are on opposite sides. We also know that A is summer, so fall would come next (B).
7. Vernal: D, Summer: A, Autumnal: B, Winter: C
8. On picture B, you can see North America on the side where there's no sun, so B shows North America at night. On picture A, you can see a part of Alaska is in nighttime too.
9. In relation to the Sun, Earth is closer to the sun because it is in summer solstice, so as the Earth moves closer to the Sun, it will become warmer.
10. In relation to the Sun, Earth is further from the Sun because it is in winter solstice, so as the Earth moves away from the Sun, there will be more cold temperatures.
