The cause of the change of seasons:
Seasons change due to the tilt of the earth's axis. This tilt is approximately 23.5 degrees relative to its orbit around the sun. This tilt is the primary reason for the change in seasons on Earth.
Key points:
- When a particular hemisphere is tilted towards the sun, it experiences summer because the sun's rays hit that hemisphere more directly, leading to warmer temperatures.
- Conversely, when a hemisphere is tilted away from the sun, it experiences winter because the sun's rays are spread out over a larger area, resulting in cooler temperatures.
- As the Earth orbits the sun throughout the year, the tilt of its axis causes different parts of the planet to receive varying amounts of sunlight, leading to the four seasons: spring, summer, autumn, and winter.
Impact of the tilt of the earth's axis:
- The tilt of the earth's axis causes the length of daylight and the angle at which sunlight hits the earth's surface to change throughout the year.
- This change in sunlight distribution results in varying temperatures and weather patterns, which we experience as the different seasons.
- The tilt also affects the intensity of sunlight, with the summer hemisphere receiving more direct sunlight and the winter hemisphere receiving less direct sunlight.
In conclusion, the tilt of the earth's axis is the primary factor that leads to the change of seasons on Earth. It influences the distribution of sunlight and temperature across the planet, creating the distinct seasonal patterns that we observe.
