Which Atmosphere term is correctly associated with location: “located mainly in the stratosphere”, and also with “absorbs much of the Sun's harmful ultraviolet radiation”?

Correct Answer: Option B — Ozone layer. Ozone layer is correct because it is located mainly in the stratosphere. Ozone layer is also associated with absorbs much of the Sun's harmful ultraviolet radiation. A further identifying fact is that Ozone layer is absorbs much of the Sun's harmful ultraviolet radiation. Another useful fact is that Ozone layer is associated with its depletion increases surface UV exposure. Why the other options are incorrect: Option A — Jet stream: It is generally found near the tropopause and is associated with mainly flows from west to east. Option C — Trade winds: It is blow from subtropical highs toward the equatorial low and is associated with deflected westward by the Coriolis effect. Option D — Westerlies: It is blow between subtropical highs and subpolar lows and is associated with generally flow from west to east. Exam Takeaway: Link Ozone layer with “located mainly in the stratosphere” and “absorbs much of the Sun's harmful ultraviolet radiation” for quick revision.
