    Why would an astronaut on Mars need a spacesuit?

    • A.

      An astronaut on Mars would need a spacesuit because the air is so thin.

    • B.

      An astronaut on Mars would need a spacesuit because the air is so thick.

    • C.

      An astronaut on Mars would need a spacesuit because the atmosphere is so thick.

    Correct Answer
    A. An astronaut on Mars would need a spacesuit because the air is so thin.
    Explanation
    An astronaut on Mars would need a spacesuit because the air is so thin. The atmosphere on Mars is much thinner than Earth's, with only about 1% of the atmospheric pressure. This means that there is not enough oxygen for humans to breathe and the lack of pressure would cause fluids in the astronaut's body to boil. Therefore, a spacesuit is necessary to provide a controlled environment with oxygen, temperature regulation, and pressure to keep the astronaut safe and alive on Mars.

    On Mars, water can not exist as

    • A.

      A liquid

    • B.

      An ice

    • C.

      A vapor

    Correct Answer
    A. A liquid
    Explanation
    Water cannot exist as a liquid on Mars because the atmospheric pressure is too low. The low pressure causes the boiling point of water to be significantly lower than on Earth, which means that any liquid water would quickly evaporate and turn into vapor. Additionally, the extremely cold temperatures on Mars would cause any liquid water to freeze into ice. Therefore, water can only exist on Mars as either ice or vapor.
