    D Becquerel Correct Answer Incorrect Answer

    Solution

    The thickness of the ozone layer is measured in Dobson Units (DU). A Dobson Unit is a measure of the total amount of ozone in a column of air stretching from the Earth's surface to the top of the atmosphere. One Dobson Unit represents a layer of ozone that would be 0.01 millimeters thick under standard temperature and pressure conditions.
