Diagrams illustrating Earth's tilt and sunlight distribution to explain seasonal changes at the poles.

Let’s go step by step to understand what’s happening in each diagram.

---

First Diagram (Top Box):

- Sunlight is coming from the right.
- The North Pole is tilted toward the sunlight.
- That means the Northern Hemisphere is getting more direct sun and longer days → it’s summer there.
- The South Pole is tilted away from the sun → shorter days, less sun → it’s winter there.
- Since the North Pole is tilted toward the sun, it gets the most hours of sunlight (possibly 24 hours!).
- The South Pole, being tilted away, has the shortest days and longest nights.

So for questions 5–8:

5. North Pole = summer → a. summer
6. South Pole = winter → c. winter
7. Most sunlight = North Pole → a. North Pole
8. Shortest days/longest nights = South Pole → b. South Pole

Second Diagram (Bottom Box):

- Sunlight is coming from the left.
- Now the South Pole is tilted toward the sunlight.
- So Southern Hemisphere = summer, Northern Hemisphere = winter.
- South Pole gets most sunlight.
- North Pole is tilted away → shortest days, longest nights.

So for questions 1–4:

1. North Pole = winter → c. winter
2. South Pole = summer → a. summer
3. Most sunlight = South Pole → b. South Pole
4. Longest nights/shortest days = North Pole → a. North Pole
