Seasons of the Year

1.Why Are Winters Not As Humid As Summer?

• Due to a rise in temperature during summer, the rate of evaporation increases, leading to an increase in the amount of water vapour in the air.
• This situation leads to humidity.
• Whereas in winter, the temperatures fall, and the rate of evaporation decreases, leading to a decrease in humidity.

2.What Is an Equinox?

• An equinox is an event when the Sun remains parallel to the equatorial region of the Earth.
• During the equinox, the hours of day length and night on the Earth become equal.
• The equinox happens twice a year.

3.Why Does Earth’s Revolution Around the Sun Creates Different Seasons?

• Earth is always tilted when it revolves around the Sun. The Earth's orbit around the Sun is oval.
• Due to the tilt of Earth when a part of Earth is leaning towards the Sun, it gets direct sunlight for a long time. In conclusion, this part has Summer.
• At the same time, the opposite part of Earth has leaned away from the Sun and gets less direct sunlight, which causes winter in that area.
• This situation changes every three months, which is how the Earth's revolution around the Sun causes different seasons.
