Chapter 16, Problem 1RQ

Why would you include the Moon in a comparison of the Terrestrial planets?

To determine

The reason for Moon is compared to Terrestrial planets.

Explanation of Solution

Introduction:

Terrestrial planets are those planets which are composed of metals and silicates rocks. Terrestrial planets are the inner planets closer to Earth.

Terrestrial planets are those planets which show their primary constituents as metals and silicates rocks. The surface of terrestrial planets is generally solid. The terrestrial planets are very large.

Moon shows its primary constituents as metals and silicates rocks. The surface of Moon is solid. But the inner iron core of Moon is much smaller than the planets.

So, Moon is compared to the terrestrial planets. But as it is not a planet it is a satellite. Thus, Moon is not a terrestrial planet it is just compared with the terrestrial planet.
