Question

Ozone depletion in the stratosphere layer of the atmosphere is responsible for which of the following?

• A. Increase of UV radiations reaching Earth's surface
• B. Cooling of Earth's atmosphere
• C. Increase in greenhouse effect
• D. Increase in infrared radiations in the troposphere

Answer 1

Answer:

A. Increase of UV radiations reaching Earth's surface

• Ozone depletion in the stratosphere allows more ultraviolet (UV) radiation to reach the Earth's surface.

• A diminished ozone layer allows more UV radiation to reach the Earth's surface.

• For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems.

• Increased UV can also lead to reduced crop yield and disruptions in the marine food chain.
