Q

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?

🔍 Key Concepts

• Structure of Earth’s 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

💭 Think About

• 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 “hole” over Antarctica and sunscreen/skin cancer concerns?

✅ Before You Answer

• 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).
