    What happens to temperature as you go higher in the troposphere?

    • It gets hotter

    • It gets colder

    • It stays the same

    • It is always changing

    Correct Answer
    A. It gets colder
    Explanation
    As you go higher in the troposphere, the temperature decreases. This is because the troposphere is the lowest layer of the Earth's atmosphere, and it is closest to the surface. The temperature in the troposphere decreases with altitude due to the decrease in air pressure. As the air pressure decreases, the air molecules spread out and the heat energy becomes less concentrated, resulting in a decrease in temperature. Therefore, it gets colder as you go higher in the troposphere.

    What happens to temperature as you go higher in the stratosphere?

    • It stays the same

    • It gets hotter

    • It gets colder

    • It is always changing

    Correct Answer
    A. It gets hotter
    Explanation
    As you go higher in the stratosphere, the temperature actually increases. This is because the stratosphere contains the ozone layer, which absorbs and filters out a large amount of the sun's harmful ultraviolet (UV) radiation. The absorption of UV radiation causes the temperature to rise in the stratosphere, making it hotter than the lower layers of the atmosphere.
