Which of the following is included in the list of terrestrial planets?

The correct response, Earth, is a terrestrial planet, which is characterized by its solid rocky surface. Terrestrial planets are primarily composed of silicate rocks or metals and have a comparatively thin atmosphere. In our solar system, the terrestrial planets include Mercury, Venus, Earth, and Mars.

In contrast, the other options—Jupiter, Uranus, and Neptune—are classified as gas giants or ice giants. Jupiter, for instance, is predominantly made up of hydrogen and helium, lacking a solid surface, while both Uranus and Neptune have significant amounts of ice and are known for their gaseous compositions. This distinction is crucial in understanding the differences between terrestrial and gas/ice giant planets.
