Why do four seasons occur?

Answer 1

The cause of the seasons is the tilt of the Earth's axis of rotation (line from one pole to the other) with respect to the plane of its orbit around the Sun. During the course of the year, this changes the length of the day, and the angle of the Sun's rays, for all locations except those in the tropics near the equator.

The seasons are not experienced the same way in every location, due to winds, currents, and local weather patterns. The seasons are reversed north or south of the equator : when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa.

• Summer: the Sun's rays are more directly overhead, temperatures are warm, days are longer
• Fall : the Sun's rays are less directly overhead, temperatures become cooler, days become shorter
• Winter: the Sun is farthest from directly overhead, temperatures are lowest, days are shortest
• Spring: the Sun becomes higher in the sky, temperatures become warmer, days become longer

Answer 2

Seasons occur because the orientation between the sun and the earth's axis changes over the year, even though the earth's axis always points to the same position in the sky. At one time of year, the northern end of the earth's axis is tilted most towards the sun. At that time, the June solstice, the sun's rays are strongest in the Northern Hemisphere. At the June solstice, summer starts in the Northern Hemisphere and winter in the Southern Hemisphere.The opposite occurs in December, when the southern end of the earth's axis is tilted most towards the sun. That date is called the December solstice. On this date, summer begins in the Southern Hemisphere and winter in the Northern Hemisphere. The intermediate position, when neither end of the earth's axis is tilted away or towards the sun, occurs twice, in September and March. The sun's rays are strongest over equatorial areas. In September, spring begins in the Southern Hemisphere and fall in the Northern Hemisphere. In March, fall begins in the Southern Hemisphere and spring in the Northern Hemisphere.

Answer 3

Seasons occur due to the tilt of the earth and the earth's revolution around the sun. The season are the opposite of each other in the northern and southern hemisphere. So when it is winter in the northern hemisphere, then it is summer in the southern hemisphere.

Answer 4

The four seasons occur due to the Earth's tilted axis as it orbits the Sun. As the Earth revolves around the Sun, different parts of the planet receive varying amounts of sunlight, causing changes in temperature and weather patterns. This creates the cycle of spring, summer, autumn, and winter.

Answer 5

because there are four seasons only

Answer 6

They occur because by the tilt of the Earth's axis

Answer 7

due to the tilt of the earth and the sun
