What are 3 facts about the ozone layer?
Facts About the Ozone Layer
- The word “ozone” means smelly in Greek because the gas has a strong odor.
- CFC molecules are highly stable and can last for up to 100 years.
- One chlorine molecule from a CFC can destroy up to 100,000 ozone molecules.
- Ultraviolet rays can also have bad effects on nature.
Which layer of the atmosphere is also called Ozonosphere?
ozone layer
ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O3).
What is the importance of ozone layer?
Why is Ozone Layer important? Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.
How many types of ozone layer are there?
Ozone or “O3” is a colorless gas composed of three atoms of oxygen (O3). There are two types of ozone, both “good” ozone and “bad” ozone.
How many ozone layers are there?
Ozone molecules (O3) have three oxygen atoms. Ozone is found in two different layers in Earth’s atmosphere.
How thick is the ozone layer?
3 millimeters
Over the Earth’s surface, the ozone layer’s average thickness is about 300 Dobson Units or a layer that is 3 millimeters thick. Ozone in the atmosphere isn’t all packed into a single layer at a certain altitude above the Earth’s surface; it’s dispersed.
Who discovered ozone hole?
In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It’s 36 years since scientists first discovered the hole in the ozone layer.
Who first discovered the ozone layer?
The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson.
Why is it called ozone?
In 1839, he succeeded in isolating the gaseous chemical and named it “ozone”, from the Greek word ozein (ὄζειν) meaning “to smell”. For this reason, Schönbein is generally credited with the discovery of ozone.
What is the Colour of ozone layer?
The ozone layer is a colorless layer of gas. However, it scatters just enough light at the blue end of the spectrum to give the sky its blue color.
How big is the ozone hole?
9.6 million square miles
This year, NASA satellite observations determined the ozone hole reached a maximum of 9.6 million square miles (24.8 million square kilometers) – roughly the size of North America – before beginning to shrink in mid-October.
