Which answer best describe the role of the ozone layer?

The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin, damaging DNA molecules in plants and animals.

What is ozone layer short answer?

The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

What is the role 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.

What is the role of ozone layer in protecting the atmosphere?

The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. The ozone layer filters out most of the sun’s harmful UV radiation and is therefore crucial to life on Earth.

How do we protect 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.

Does the ozone layer have a hole?

Yes and no. The ozone hole is basically a human-caused hole in the ozone layer above the South Pole during the Southern Hemisphere’s spring. The ozone layer, which lies high up in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun.

Are there holes in the ozone layer?

The 2020 Antarctic ozone hole grew rapidly from mid-August and peaked at around 24.8 million square kilometres on 20 September 2020, spreading over most of the Antarctic continent. It was the longest-lasting and one of the largest and deepest holes since the ozone layer monitoring began 40 years ago.

In what layer is the ozone found?


What are the benefits of ozone layer?

The ozone layer protects life on earth by absorbing harmful ultraviolet radiation. As the layer thins, the upper atmosphere grows colder, causing winds in the stratosphere and in the troposphere below to shift, displacing jet streams and storm tracks.

How are humans affecting the ozone layer?

gases. Human activities cause the emission of halogen source gases that contain chlorine and bromine atoms. These emissions into the atmosphere ultimately lead to stratospheric ozone depletion. These activities have typically caused the emission of halogen-containing gases to the atmosphere.

What is the Colour of ozone?

It is a pale blue gas and consists of three oxygen atoms. Formed in the ozone layer of the stratosphere, it is harmful to life. Ozone, O3, is an allotrope of oxygen. Ozone has pungent an odor, and its color is blue- black in its solid and liquid form.

What are the 3 oxygen atoms in the ozone layer?

A molecule of ozone (O3) contains three oxygen (O) atoms bound together. Oxygen molecules (O2), which constitute 21% of Earth’s atmosphere, contain two oxygen atoms bound together.
