Why do have four seasons?

 

The four seasons are a result of the Earth's tilt on its axis. As the Earth orbits the sun, different parts of the planet are exposed to more or less direct sunlight. This causes the seasons.

The Earth's axis is tilted at an angle of about 23.5 degrees. This tilt is what causes the Earth to have seasons. As the Earth orbits the sun, different parts of the planet are exposed to more or less direct sunlight. This causes the seasons. The longest day of the year is the summer solstice, when the Earth's North Pole is tilted toward the sun. The shortest day of the year is the winter solstice, when the Earth's South Pole is tilted toward the sun. The changing angle of the Earth's tilt throughout the year also causes the seasons. As the Earth's axis tilts toward the sun, the days become longer and the weather becomes warmer. This is because the sun's rays hit the Earth's surface at a more direct angle. As the Earth's axis tilts away from the sun, the days become shorter and the weather becomes cooler. This is because the sun's rays hit the Earth's surface at a less direct angle.
