Question

How are the seasons formed?

Answer 1

Hint: Earth has different seasons in different parts of the country. Hipparchus of Nicaea is the one who discovered seasons in the world. Autumn, Spring, Winter, and Summer are some of the main seasons all over the world. Most of us think that the Earth is close to the Sun in summer and farthest in winter.

Complete answer:
Seasons occur due to the orbit of the Earth. While the Earth revolving around the sun North pole doesn’t change, it always points the same way. Many think that the Earth revolves around the sun in a perfect circle but the truth is the Earth revolves around the sun in an elliptical orbit.

The time taken by the Earth to rotate on its axis is 23 hours, 56 minutes, and 4.09053 seconds. This period is called the sidereal period. The Earth is tilted a bit but the axis always points the same direction so that we have sun rays throughout the year in different parts of the country

While revolving, when the Earth’s north pole is tilted towards the sun then it is summer as no other region or area in the earth gets the direct sun rays at any other time of the year
So when the Earth’s south pole is tilted towards the sun then it is winter in December. Due to the low intensity of sunlight in winter cold air masses are formed in North America, Europe, and Asia

Note: The axis of the planet Earth is tilted at around 23.4 degrees. This is why different parts of the globe get different intensity and amount of sunlight or sun rays, thus essentially causing the occurrence of different seasons. Earth takes 23 hours, 56 minutes, and 4.09053 seconds to rotate on its axis.Moreover this is called the sidereal period.
