Question

A Sense of Proportion:Arrange the following in order of increasing length:1. one rotation of Earth2. one revolution of Moon around Earth3. any one of Earth's seasons4. one revolution of Earth around Sun5. one precession cycle

Answer 1

In increasing order of length

Option (1) < Option (2) < Option (3) < Option (4) < Option (5)

Step-by-step explanation:

The earth rotates around its imaginary axis once every 24 hours.

The moon is the natural satellite of earth that orbits around the earth once every 28 days (approximately).

Seasons are the contrasting phenomenon that occurs on earth once every 3 months and is caused due to the tilt of the earth's axis.

Earth orbits around the sun once every 365 days.

The precision cycle of earth is approximately 26000 years (this means that there occurs 1° change every 72 years).

Thus, the time duration of each of the above can be arranged in an increasing order which is given below-

Option (1) < Option (2) < Option (3) < Option (4) < Option (5)
