Question
What is true of Mars?Group of answer choicesDefinite microfossils have been found.Its atmosphere is mostly water vapor.Iron oxide on the surface is responsible for its reddish color.A pool of water was discovered by the Mars Rover.Its magnetic field is stronger than Earth's
Solution
The true statement about Mars is "Iron oxide on the surface is responsible for its reddish color." This is because the surface of Mars contains a high amount of iron oxide, or rust, which gives the planet its distinctive red color.
The other statements are not accurate. While there have been indications of possible microfossils or signs of past microbial life, no definite microfossils have been confirmed. Mars' atmosphere is not mostly water vapor, but rather mostly carbon dioxide. While there have been discoveries of evidence suggesting past water activity and ice on Mars, no pools of liquid water have been discovered by the Mars Rover. Lastly, Mars' magnetic field is not stronger than Earth's; in fact, it is much weaker.
