I. Mercury, Venus, Earth and Mars are terrestrial planets having low densities as compared to other planets.
II. They lie between the Sun and the belt of asteroids.
III. Their lower gravity can hold the escaping gases.
Which of the statements given above is/are correct?
II only
The correct answer is II only.
However, their atmospheres are not as thick as those of the gas giants. Due to their stronger gravitational pull, terrestrial planets can hold gases despite their relatively thinner atmospheres compared to gas giants. Thus, this statement is incorrect. Given the analysis, the correct statement is II only .
