3. What is the significance of the revolution of the Earth around the Sun?
4. What is the adjustment made in our solar calendar?
5. Define equinox and state its importance.​

Answer 1

Answer:

3.Revolution is the term used to describe the path (or orbit) of Earth through space. Earth's revolution around the sun is responsible for seasonal change and leap years. This path is shaped like an ellipse and has points when Earth is closer to the sun and farther from it.

4.A solar calendar is a calendar whose dates indicate the position of Earth on its revolution around the Sun or, equivalently, the apparent position of the sun moving on the celestial sphere. The other commonly used system is a lunar calendar which dates the months based on cycles of the lunar phases. The Gregorian calendar, widely accepted as standard in the world, is an example of solar calendar.

5.An equinox is an event in which a planet's subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemisphere experience roughly equal amounts of daytime and nighttime.
