Questions and Answers

Why is the ozone layer primarily found in the stratosphere?

  • The stratosphere has the right conditions for ozone formation and stability. (correct)
  • The stratosphere is closer to the sun, allowing for better absorption of ultraviolet radiation.
  • Ozone efficiently filters harmful UV radiation in the lower atmosphere.
  • Ozone is created in the stratosphere by a chemical reaction involving sunlight.

    • What role do greenhouse gases play in warming the lower atmosphere?

  • Greenhouse gases absorb and reflect sunlight, causing warming.
  • Greenhouse gases trap heat radiated from the Earth's surface, leading to warming. (correct)
  • Greenhouse gases generate additional heat through chemical reactions in the lower atmosphere.
  • Greenhouse gases create a protective barrier that prevents heat loss from the lower atmosphere.

    • How do global air circulation patterns and ocean currents impact climate?

  • They lead to consistent climate conditions in all regions of the world.
  • They create localized climate zones without any global impact.
  • They help distribute heat and precipitation evenly throughout the globe. (correct)
  • They cause random variations in climate patterns across different areas of the Earth.
