All the planets (without exception)
A. have solid surfaces
B. have atmospheres much thicker than Earth’s
C. revolve around the Sun in the same direction
D. have satellites orbiting around them
E.rotate on their axes in the same direction that they revolve around the Sun
The Correct Answer and Explanation is :
The correct answer is C. revolve around the Sun in the same direction.
Explanation:
- Option A: Have solid surfaces
This is not true for all planets. While some planets, like Earth, Mars, and Mercury, have solid surfaces, others, like the gas giants Jupiter, Saturn, Uranus, and Neptune, do not have solid surfaces. These planets are composed mostly of gas and liquid, with no well-defined solid surface. Therefore, this option is incorrect. - Option B: Have atmospheres much thicker than Earth’s
Not all planets have atmospheres that are thicker than Earth’s. While gas giants like Jupiter and Saturn have very thick atmospheres, planets like Mercury and Mars have very thin atmospheres, and Venus, although its atmosphere is thick, has a composition and pressure quite different from Earth’s. Hence, this option is not correct. - Option C: Revolve around the Sun in the same direction
This is the correct answer. All planets in our solar system revolve around the Sun in the same direction, which is counterclockwise when viewed from above the Sun’s north pole. This consistent direction of revolution is due to the way the solar system formed from a rotating disk of gas and dust. The planets formed from this disk, and they inherited the angular momentum of the disk, which is why their orbits are in the same direction. - Option D: Have satellites orbiting around them
This is not true for all planets. While most of the planets have moons (satellites), Mercury and Venus do not have any natural satellites. This makes this option incorrect. - Option E: Rotate on their axes in the same direction that they revolve around the Sun
This is not true for all planets. While most planets rotate in the same direction as their revolution around the Sun (counterclockwise), Venus and Uranus have retrograde rotations, meaning they rotate in the opposite direction. Thus, this option is also incorrect.
In conclusion, option C is the only correct statement.
