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.
Which of the following are consequences of ozone depletion 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.
Which of the following is a health risk associated with ozone depletion quizlet?
Since ozone absorbs UV radiation, having less ozone in the stratosphere means more UV radiation will reach the troposphere. This causes greater risk of skin cancer and cataracts .
How does the absorption of ultraviolet radiation by the ozone layer help sustain life quizlet?
How does the absorption of ultraviolet radiation by the ozone layer help sustain life? This process helps maintain the temperature of the Earth . It keeps a low level of harmful ultraviolet radiation from reaching living organisms. This process keeps ozone concentrations in the troposphere at lower levels.
How does the ozone layer affect life on Earth Site 1 quizlet?
How does the absorption of ultraviolet radiation by the ozone layer help sustain life? ... It keeps a low level of harmful ultraviolet radiation from reaching living organisms. c. This process keeps ozone concentrations in the troposphere at lower levels.
What are 3 causes of depletion to the ozone layer?
Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.
How ozone is both beneficial and detrimental to human health?
The ozone layer is beneficial because it protects us from the ultraviolet (UV) rays from the sun. Without it, survival would be difficult. It is harmful by containing all the pollution and chemicals . That damages our lungs and causes chest pain, coughing,etc.
What is the main impact of ozone depletion?
Ozone layer depletion increases the amount of UVB that reaches the Earth’s surface . Laboratory and epidemiological studies demonstrate that UVB causes non-melanoma skin cancer and plays a major role in malignant melanoma development.
Where we can find the ozone layer?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface . It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
Which is an effect of the ozone depletion over Antarctica quizlet?
The ozone hole “might” affect winds and cloud formation over Antarctica , possibly impacting the “regional” climate.
How does the ozone layer help maintain ground level air quality quizlet?
How does the ozone layer help maintain ground-level air quality? The ozone layer absorbs a large portion of incoming UV radiation , which keeps ground-level ozone from forming. A higher percentage of UV radiation entering the troposphere would allow a greater amount of ozone to form in the troposphere.
What harm is caused by the presence of CFCs?
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer , which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.
Which of the following is a health risk associated with ground-level ozone topic test?
Ground-level ozone is a pollutant that is harmful to organisms when it is breathed in. Ozone in the troposphere can also cause an increase in surface temperatures. Depletion of ozone in the stratosphere causes health and environmental risks indirectly. ... This causes greater risk of skin cancer and cataracts .
What important role does the ozone layer play in Earth’s atmosphere quizlet?
Why is ozone an important gas in the atmosphere? It helps absorb radiation from the sun . *Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun.
Which of the following best describes the greenhouse effect on Earth quizlet?
Which of the following best describes how the greenhouse effect works? A planet’s surface absorbs visible sunlight and returns this absorbed energy to space as infrared light . Greenhouse gases slow the escape of this infrared radiation, which thereby heats the lower atmosphere.
Why is the ozone layer so important for humans?
The ozone layer protects the Earth against most UVB coming from the sun . It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen. However, these precautions will become more important as ozone depletion worsens.
