Answers
Answer:
a)If the earth's axis was vertical instead of inclined,
All the places on the earth would have had the same temperature throughout the year.
There would have been no seasons.
The length of the day and night would have been the same.
b)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.
c)Rotation is the movement of an object on its own axis. On the other hand, revolution is the complete round trip around something, i.e. another object or center. Rotation is when the object spins around an internal axis. Conversely, revolution is when the object travels around an external axis
d)
Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
