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.

In this regard, why is ozone important in the atmosphere quizlet?

Stratospheric ozone is important in the earth system because it absorbs ultraviolet radiation from the sun, protecting life on earth. Ozone is a relatively rare and unstable molecule composed of three oxygen atoms O3. This layer of the atmosphere is made up of five layers of gases, especially oxygen and nitrogen.

Beside above, what is the role of ozone layer in the upper part of atmosphere? This region of the atmosphere is called the stratosphere. Ozone thus plays a key role in the temperature structure of the Earth's atmosphere. Without the filtering action of the ozone layer, more of the Sun's UV-B radiation would penetrate the atmosphere and would reach the Earth's surface.

Additionally, how much ozone is in the atmosphere?

The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million.

Where is the ozone formed and stored?

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

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.

What is the main function of the ozone layer quizlet?

What is the purpose of the ozone layer? To stop excessive amounts of ultraviolet radiation reaching the Earth's surface. It absorbs the UV rays to prevent them from reaching the ground.

In which layer of the atmosphere does most weather occur?

1) The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. 2) Many jet aircrafts fly in the stratosphere because it is very stable.

What is the composition of atmosphere?


The atmosphere is composed of a mix of several different gases in differing amounts. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

How are chlorofluorocarbons used?

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. Individual CFC molecules are labeled with a unique numbering system.

What is ozone and why is ozone important to life on Earth quizlet?

What is ozone and why is ozone important to life on Earth? A form of oxygen that has three oxygen atoms in each molecule instead of the usual two and ozone absorb ultraviolet radiation emitted by the Sun. The ozone in the stratosphere absorbs ultraviolet radiation from the sun, which warms the air.

What harms the ozone layer?

Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

How can we save the 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.

Is there a hole in the ozone layer?


The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric container. Within this polar vortex, over 50 percent of the lower stratospheric ozone is destroyed during the Antarctic spring.

Are ozone machines safe?

Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation.

What is ozone made of?

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation.

Is ozone a greenhouse gas?

Ozone isn't a typical greenhouse gas. It has two distinct functions in the atmosphere. High in the stratosphere, it absorbs ultraviolet light from the sun and protects the earth. Near the ground, it serves as a pollutant and contributor to smog and also has greenhouse characteristics.

Does the Ozone Layer move?

The amount of ozone in the stratosphere varies naturally throughout the year as a result of chemical processes that create and destroy ozone molecules and as a result of winds and other transport processes that move ozone molecules around the planet.

What are the 5 main layers of atmosphere?


Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.

What does ozone look like?

Ozone is a colorless gas. But ozone also absorbs harmful components of sunlight, known as “ultraviolet B”, or “UV-B”. High above the surface, above even the weather systems, a tenuous layer of ozone gas absorbs UV-B, protecting living things below.

Does the ozone layer trap heat?

Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere.
