Question

    In the vertical structure of the atmosphere, which is the

    lowest layer?
    A Stratosphere Correct Answer Incorrect Answer
    B Mesosphere Correct Answer Incorrect Answer
    C Troposphere Correct Answer Incorrect Answer
    D Thermosphere Correct Answer Incorrect Answer

    Solution

    The troposphere is the lowest layer of Earth's atmosphere, extending from the surface to approximately 8-15 km, depending on latitude. This layer contains approximately 75% of the atmosphere's mass and 99% of its water vapor and aerosols. The troposphere is where most weather phenomena occur. Above the troposphere lie the stratosphere, mesosphere, and thermosphere, in ascending order.
