The reason why the categorizing moon by geological activities is helpful.
Answer to Problem 1QP
Option (a) is correct. The geological activities explain the underlying physical process on the moon.
Explanation of Solution
The moons are categorized in several manners in order to have a pattern of their study. The categorizing on the moons in terms of the geological activities occurring on the surface of the moon is considered to be the most efficient way to study the moons.
The geological activities are the activities that occur on the surface of the moons. It includes the volcanic eruptions, the lava flowing on the surface of the moon etc. The amount of geological activities occurring on the surface of the moon provides lot information about the process undergoing beneath the surface of the moon.
Therefore, studying the moons based on the geological activities occurring on the surface makes it much easier to understand the composition and the physical process occurring beneath the surface of the moon.
Conclusion:
Thus, option (a) is correct. The geological activities explain the underlying physical process on the moon.
Option (b) is incorrect. The distance from the sun does not affect the geological activity occurring on the planet.
Option (c) is incorrect. The size and composition of the moon are not explained by the geological activities.
Option (d) is incorrect. The moons vary in size from one another frequently. They are not of same size.
