Ozone layer is in the stratosphere about 20-30 km above Earths surface. Provides protective layer = acts as a shield absorbing around 90% of UV rays. Single oxygen atoms join other oxygen molecules to form triplets of oxygen atoms, or ozone molecules (O3).

Moreover, what is ozone layer and what is its importance?

Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. Without the layer of ozone in the atmosphere, it would be very difficult for anything to survive on the surface. (Think of a very bad sunburn, only much worse!)

Beside above, how do CFCs cause ozone depletion quizlet? When CFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms which react with ozone, starting chemical cycles of ozone destruction that deplete the ozone layer. One chlorine atom can break apart more than 100,000 ozone molecules.

Furthermore, what do u mean by ozone layer?

The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun.

Why is the ozone layer important quizlet?

It is a layer of ozone high in the atmosphere, and surrounds the earth. Why is the ozone layer important? This layer acts as a filter to prevent too much of the harmful ultraviolet light in sunlight from reaching earth. They are destroying the ozone layer.

What are the two types of ozone?

Ozone molecules (O3) have three oxygen atoms. Ozone is found in two different layers in Earth's atmosphere. "Bad" ozone is found in the troposphere, the layer nearest the ground. Tropospheric ozone is a harmful pollutant which forms when sunlight alters various chemicals emitted by humans.

What are the benefits of ozone layer?

The Benefits of Good Ozone
At that level, ozone helps to protect life on Earth by absorbing ultraviolet radiation from the sun, particularly UVB radiation that can cause skin cancer and cataracts, damage crops, and destroy some types of marine life.

How is ozone formed?

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis. If a freed atom collides with another O2, it joins up, forming ozone O3.

Where is ozone formed and stored?

Ozone is produced in the high stratosphere, stored in the lower stratosphere, and destroyed in the troposphere.

Where is ozone layer located?


The ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometres (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically. The ozone layer protects the earth from the suns UV Rays.

What is ozone layer in simple words?

Kids Definition of ozone layer
: a layer of the earth's upper atmosphere that is characterized by high ozone content which blocks most of the sun's ultraviolet radiation from entering the lower atmosphere.

What is the difference between good and bad ozone?

What is the difference between good and bad ozone? Good ozone is the gas that sits in the Stratosphere and stops much of the harmful ultra-violet radiation from reaching the surface of the Earth. Bad ozone is the gas that sits at ground level and can be breathed in by people and animals.

How is ozone destroyed?

When ultraviolet light waves (UV) strike CFC* (CFCl3) molecules in the upper atmosphere, a carbon-chlorine bond breaks, producing a chlorine (Cl) atom. The chlorine atom then reacts with an ozone (O3) molecule breaking it apart and so destroying the ozone.

What is ozone layer and its effects?

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.

How damaged is the ozone layer?


Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.

What does of mean?

The Meaning of OF
OF means "Old Fart" So now you know - OF means "Old Fart" - don't thank us. YW! What does OF mean?

How can we protect ozone layer?

How can we protect the ozone layer?
  1. Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process.
  2. Minimize the use of cars.
  3. Do not use cleaning products that are harmful to the environment and to us.
  4. Buy local products.

How many ozone layers are there?

Ozone is mainly found in two regions of the Earth's atmosphere. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere.

What is another name for ozone?

Another name for the ozone layer is the ozonosphere.

What is the major cause of ozone depletion?


Man-made causes of depletion of ozone layer: The main cause for the depletion of ozone is determined as excessive release of chlorine and bromine from man-made compounds such as chlorofluorocarbons (CFCs). The emission of ODS account for roughly 90% of total depletion of ozone layer in stratosphere.

How do chlorofluorocarbons affect Earth's ozone layer quizlet?

Ozone Depletion Ozone is destroyed by chlorofluorocarbons (CFC's). CFC's breakdown and release chlorine atoms which combine with O3 and break them down to O2. , CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing the chlorine that catalytically destroys ozone.

What is a direct effect on humans that increases with atmospheric ozone depletion?

Effects of the ozone hole to the environment and health
For humans, direct exposure to UV rays can lead to: Skin cancer such as melanoma, basal cells or squamous cell carcinomas. Premature aging and other skin damage. Eye damage such as cataract problems, photokeratitis or snow blindness.
