How does ozone in the stratosphere protect us?
The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
What is the purpose of the ozone in the stratosphere?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.
How does ozone in the stratosphere protect people and animals?
Explanation: The main function of Ozone layer is not allowing the harmful Ultraviolet rays reach the earth’s surface. Thus it protects both the animals and plants from the ill effects of UV rays.
What gas protects the ozone layer?
chlorofluorocarbons (CFCs)
Substances covered by the protocol are referred to as ‘controlled substances’. The main substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, methyl chloroform and methyl bromide.
How is ozone harmful to us?
How is Ozone Harmful? When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
What is the strongest evidence that Hcfcs are in the stratosphere?
What is the strongest evidence that CFCs are in the stratosphere? Measurements of CFCs in air samples from the stratosphere. What compounds have the highest ozone depletion potential? May be fined.
How do we protect the ozone layer?
How can we protect the ozone layer?
- Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process.
- Minimize the use of cars.
- Do not use cleaning products that are harmful to the environment and to us.
- Buy local products.
What happens if we breathe ozone?
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
Can you recover from ozone exposure?
The effects are reversible, with improvement and recovery to baseline varying from a few hours to 48 hours after an elevated ozone exposure.
