B. They are solid and "earth" like.
B. They are solid and "earth" like.
To determine the correct answer, let's break down the options and see which one aligns with the term "Terrestrial".
A. The presence of Earthlike oceans: While oceans are a characteristic of the Earth, this option does not fully capture the meaning of the term "Terrestrial."
B. The solid and "earth" like nature: This option seems more promising, as it suggests that the inner planets resemble Earth in terms of being solid and having similar physical characteristics.
C. Visibility from Earth: While visibility from Earth is a factor, it is not the primary reason why the inner planets are called Terrestrial.
D. The absence of atmosphere: While some inner planets do have thinner atmospheres compared to Earth, this option does not fully capture the essence of the term "Terrestrial."
Based on the analysis, the best description that explains why the inner planets are called Terrestrial is option B: They are solid and "earth" like. This description accurately conveys the idea that the inner planets have similar physical properties to Earth, such as being rocky and solid.
