The gas that exists in the stratosphere forming a protective shield that helps to protect the environment from the harmful effects of ultraviolet radiation is called what?
⢠Structure of Earthâs atmosphere, especially the stratosphere ⢠The gas that forms the protective layer against ultraviolet (UV) radiation ⢠Difference between major atmospheric gases (like nitrogen and oxygen) and trace gases
⢠Which gas is specifically associated with a named "layer" in the atmosphere that blocks UV radiation? ⢠Which of these gases is present mainly as a trace gas rather than the primary component of air? ⢠Think about common environmental discussions: which gas is linked to the âholeâ over Antarctica and sunscreen/skin cancer concerns?
⢠Identify which choice is known for forming a distinct atmospheric layer related to UV protection. ⢠Eliminate gases that are the bulk of the atmosphere rather than special protective layers. ⢠Recall which gas is discussed in environmental policy about depletion by CFCs (chlorofluorocarbons).
