Question

question 44 points 2 ozone layer depletion leads to ______. decrease of oxygen in thermosphere continuous exposure of uv radiation to humans suppression of uv radiation exposure to humans enhanced agricultural production

Explanation:

• Analyze Option 1: The ozone layer is in the stratosphere, and its depletion doesn't directly decrease oxygen in the thermosphere. So this option is incorrect.
• Analyze Option 2: The ozone layer absorbs UV radiation. When it depletes, more UV radiation reaches the Earth's surface, leading to continuous exposure of UV radiation to humans. This option is correct.
• Analyze Option 3: Ozone layer depletion increases, not suppresses, UV radiation exposure to humans. So this option is incorrect.
• Analyze Option 4: Increased UV radiation due to ozone depletion harms crops and reduces agricultural production, rather than enhancing it. So this option is incorrect.

Answer:

B. continuous exposure of UV radiation to humans
