How does the hole in the ozone layer affect global warming?
The ozone hole does not cause global warming. Ozone is a greenhouse gas, so its presence has a warming effect, and the result of declining ozone in the late 20th century has been a regional cooling of the stratosphere over Antarctica, not warming. Figure 1: The ozone layer in the stratosphere.
What happens if there is a hole in the ozone layer?
Since the ozone layer absorbs UVB ultraviolet light from the sun, ozone layer depletion increases surface UVB levels (all else equal), which could lead to damage, including an increase in skin cancer. This was the reason for the Montreal Protocol.
What problems could the Earth face because of a hole in the ozone layer?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
What caused hole in ozone layer?
The ozone hole has developed because people have polluted the atmosphere with chemicals containing chlorine and bromine. Once released from CFCs, chlorine (Cl) then reacts with ozone (O3) to form ClO and O2. ClO quickly breaks down to release the Cl atom which can repeat the process with another O3 molecule.
Why is the ozone hole a problem?
The thinning is most pronounced in the polar regions, especially over Antarctica. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
What are the dangers associated with the hole in the ozone layer quizlet?
Depletion of the ozone layer has consequences on humans, animals and plants. This typically results from higher UV levels reaching us on earth. Research confirms that high levels of UV Rays cause non-melanoma skin cancer.
Why is the ozone hole a concern?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
What is the main problem caused by the ozone hole quizlet?
radiation. 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.
