Earth Moon and the Sun Class 7 Long Question Answer

Question 1.

Explain the significance of the Earth's axial tilt in relation to seasons.

Answer:

The Earth's axial tilt of approximately 23.5 degrees causes different parts of the Earth to receive varying sunlight throughout the year, leading to distinct seasons. This tilt results in summer when a hemisphere tilts toward the Sun and winter when it tilts away.

Question 2.

Describe the process of a solar eclipse and its visibility.

Answer:

A solar eclipse occurs when the Moon passes between Earth and the Sun, blocking sunlight. It is only visible from specific areas on Earth where the Moon's shadow falls, making it a localized event compared to lunar eclipses.

Question 3.

Discuss the historical significance of eclipses and how they were perceived before scientific understanding.

Answer:

Historically, eclipses were often viewed with fear and superstition, as people lacked understanding of their causes. They were seen as omens, leading to various cultural practices and beliefs about their significance in human affairs.
