FAQs on Why Do We Have Different Seasons? Video Lecture - Science (Curiosity) Class 7 - New NCERT

1. Why do we have different seasons?

Ans. Different seasons occur due to the tilt of the Earth's axis and its orbit around the Sun. The Earth is tilted at an angle of about 23.5 degrees. As it travels around the Sun, this tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to changes in temperature and weather patterns.

2. What are the main seasons experienced on Earth?

Ans. The main seasons experienced on Earth are spring, summer, autumn (fall), and winter. Each of these seasons has distinct weather patterns and temperature ranges, influenced by the Earth's position relative to the Sun.

3. How does the tilt of the Earth affect the length of days and nights?

Ans. The tilt of the Earth affects the length of days and nights because it changes the angle at which sunlight reaches different parts of the Earth. During summer, days are longer because the Sun takes a longer path across the sky, while in winter, days are shorter due to the Sun's lower path.

4. Why do different regions experience seasons at different times?

Ans. Different regions experience seasons at different times because of their location on Earth. For example, when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. This is due to the tilt of the Earth's axis and its orbital position around the Sun.

5. How do seasons affect plant and animal life?

Ans. Seasons significantly affect plant and animal life. Many plants bloom in spring, while others may shed leaves in autumn. Animals may hibernate in winter or migrate to warmer areas during colder months. These seasonal changes are essential for the life cycles and survival of various species.
