This printable science worksheet challenges students to identify the dates of equinoxes and solstices based on Earth's position in its orbit.

The image you've uploaded is a worksheet titled "Seasons of the Year", which appears to be an educational activity designed to teach students about how Earth's tilt and orbit around the Sun cause the changing seasons. The task involves labeling diagrams and answering questions based on Earth’s position in its orbit.

Let me walk through the problem and explain the solution step by step:

🔍 Understanding the Diagram

The diagram shows:
- The Sun in the center.
- Earth at four different positions in its orbit (labeled A, B, C, D).
- Each Earth has a tilted axis shown with an arrow.
- Arrows indicating the direction of Earth’s orbit around the Sun.
- The North Pole is marked on each Earth.

This represents Earth’s tilted axis (about 23.5°) and how it remains pointed in the same direction throughout the year as Earth orbits the Sun.

🌍 Key Concept: Why We Have Seasons

Seasons are caused by:
1. Earth’s axial tilt (not because of distance from the Sun).
2. As Earth orbits the Sun, different parts of Earth receive varying amounts of sunlight due to this tilt.
- When the Northern Hemisphere is tilted toward the Sun → Summer.
- When it is tilted away → Winter.
- When neither hemisphere is tilted toward or away → Spring or Fall (Equinoxes).

✔ Step-by-Step Solution

#### Step 1: Identify the Positions
Label each Earth (A, B, C, D) with the correct season for the Northern Hemisphere.

We can determine the season by looking at whether the North Pole is tilted toward or away from the Sun.

- Position A: North Pole is tilted toward the Sun → Summer (June)
- Position B: Earth is midway between A and C; neither pole is tilted toward Sun → Autumn (Fall) (September)
- Position C: North Pole is tilted away from the Sun → Winter (December)
- Position D: Earth is midway between C and A; neither pole is tilted → Spring (Vernal Equinox) (March)

So, the labels should be:
- A: Summer
- B: Autumn
- C: Winter
- D: Spring

> Note: The order of the positions may vary depending on the diagram, but typically they go clockwise: Spring → Summer → Autumn → Winter.

#### Step 2: Match Dates to Positions
From the table provided:
| Season | Date |
|------------|------------|
| Spring | March 21 |
| Summer | June 21 |
| Autumn | September 22 |
| Winter | December 22 |

Now match these dates to the positions:
- March 21 → D (Spring)
- June 21 → A (Summer)
- September 22 → B (Autumn)
- December 22 → C (Winter)

#### Step 3: Answer the Question
The prompt says:
> "On the diagram above, label the name of the season and the date that matches each picture of the year."

So, you would write:
- At A: Summer – June 21
- At B: Autumn – September 22
- At C: Winter – December 22
- At D: Spring – March 21

🧠 Additional Notes

- The equinoxes (spring and autumn) occur when day and night are nearly equal in length.
- The solstices (summer and winter) have the longest and shortest days of the year.
- Earth's tilt stays constant, but its position in orbit changes, causing seasonal shifts.

✔ Final Answer Summary:

Label the Earth positions as follows:
- A: Summer – June 21
- B: Autumn – September 22
- C: Winter – December 22
- D: Spring – March 21

This reflects the correct alignment of Earth’s tilt and orbit with the seasons in the Northern Hemisphere.
