Question
Imagine Mars had been the size of the Earth, which line of thought would make reasonable sense?
A.Mars would likely have liquid water: its larger size would ensure that Mars could keep its magnetic field, preventing water molecules from being stripped apart by solar wind particles.
B.Mars would likely have tectonic activity, but its appearance would be the same (red) since this merely reflects the type of minerals that were present as building blocks at the location where Mars formed.
C.Mars would look very similar to what it looks like now, only bigger: it is quite a bit farther away from the Earth than the Sun, so it would still be cold and lifeless.
D.Mars would orbit the Sun closer because of its larger mass, resulting in a potentially habitable planet.
Explanation / Answer
only option B seems to be logical:
Mars would likely have tectonic activity, but its appearance would be the same (red) since this merely reflects the type of minerals that were present as building blocks at the location where Mars formed.
