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 mainly flows from west to east and is associated with it strongly influences weather systems and aviation routes. Option B — Trade winds: It is deflected westward by the Coriolis effect and is associated with help drive tropical ocean currents. Option D — Westerlies: It is generally flow from west to east and is associated with steer many temperate cyclones. Exam Takeaway: Link Ozone layer with “absorbs much of the Sun's harmful ultraviolet radiation” and “its depletion increases surface UV exposure” for quick revision.
