What are 5 facts about ozone?
Top 10 facts about Ozone
- Ozone was first discovered and isolated by the German-Swiss chemist Christian Friedrich Schönbein in 1839.
- One molecule of ozone consists of three oxygen atoms.
- Ozone near ground level may be harmful.
- The Montreal Protocol to ban ozone-depleting chemicals such as CFCs was signed in 1989.
What is special about 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 are 3 facts about the ozone layer?
Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun. Without ozone, the Sun’s intense UV radiation would sterilize the Earth’s surface. Ozone screens all of the most energetic, UV-c, radiation, and most of the UV-b radiation. Ozone only screens about half of the UV-a radiation.
What is ozone layer made of?
The ozone layer, also called the stratosphere, is composed of the ozone gas (90% of the total ozone in the atmosphere). The ozone has three oxygen atoms, and it is the result of the action of Ultra Violet (UV) radiation on oxygen molecules, composed of two oxygen atoms.
What is ozone layer explain to kids?
Ozone is a natural part of Earth’s upper atmosphere. This part of the atmosphere, about 15 miles (24 kilometers) above the surface, is called the ozone layer. It protects people by absorbing harmful rays from the sun. If they reach Earth, these rays can cause skin cancer, eye diseases, and other health problems.
How does the ozone layer protect us?
The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer.
How does ozone layer protect us?
How thick is the ozone layer?
3 millimeters thick
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 layer?
The Ozone Layer was discovered by the French physicists Charles Fabry and Henri Buisson in 1913.
What are the 2 types of ozone?
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.
What temperature is the ozone layer?
The Ozone layer starts about 20 km above the earth surface to about 60 km. The temperatures rise from around -76°F (-60°C) at the start of the stratosphere to about 5°F (-15°C) at the stratopause.
Can humans survive without the ozone layer?
Life couldn’t exist without this protective ozone, which is also called the “ozone layer.” The sun gives off light, heat, and other types of radiation. Too much UV (ultraviolet) radiation can cause skin cancer, cataracts, and harm plants and animals.
