Exploring the Science Behind Seasons

The video explains why we have seasons, debunking the myth that it's due to Earth's proximity to the Sun. Instead, it's the tilt of Earth's axis that causes seasons. Through demonstrations, the video shows how Earth's tilt affects sunlight concentration, leading to temperature variations and different seasons. The video also compares sunlight distribution in December and June, illustrating how the same amount of light can be more concentrated or spread out, affecting warmth and resulting in winter or summer.

What is a common misconception about why we have seasons?

• The Moon affects the seasons.

• The Earth is closer to the Sun.

• The Earth is tilted.

• The Sun's energy varies.
