Ozone layer protects the Earth from the harmful radiation. Ozone is a type of oxygen that is abundant in the stratosphere, and is a pollutant at lower altitudes.

What protects Earth from harmful radiation in the stratosphere?

Ozone
Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone. This in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

Which help protect the Earth from radiation?

The ozone layer
The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects.

How can 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.

Why does the stratosphere get warmer with altitude?

When UV light is absorbed by oxygen and ozone, heat is generated, which is why the stratosphere gets warmer with altitude. The ozone layer in the stratosphere shields life on Earth from most UV-B and UV-C, the most harmful varieties of ultraviolet radiation.

Why is ozone important to life on Earth?

Near the ground, ozone is an air pollutant that causes lung damage and asthma attacks. But 10 to 30 miles above the Earth’s surface (16-48 km), ozone molecules protect life on Earth. They help shield our planet from harmful solar radiation.

Where does 90% of the ozone layer come from?

The ozone layer, in the stratosphere, is where about 90% of the ozone in the Earth system is found. But ozone makes up only one to ten out of every million molecules in the ozone layer. (The rest of the molecules are mostly nitrogen and oxygen, like the air we breathe.)

When do the ozone levels go down in Antarctica?

They detected a 10% drop in ozone levels during September, October, and November—the Antarctic spring. Since ozone concentrations over this region often vary from season to season, the researchers weren’t concerned, but record low ozone levels kept occurring nearly every spring.
