What is ozone in one word answer?
Ozone is a colourless gas which is a form of oxygen. There is a layer of ozone high above the earth’s surface. Ozone is best known for its role in screening the Earth from harmful ultraviolet rays from the Sun.
What is ozone kid definition?
Ozone is a pale blue gas. It is a form of oxygen. The common form of oxygen is a gas that all animals need to breathe. But ozone is poisonous and explosive. It differs from common oxygen in its chemical makeup.
What is ozone layer in short?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
What is the best definition of ozone hole?
noun. geography. an area of the atmosphere where the ozone layer is particularly thin or absent.
What causes ozone?
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
Why is ozone important?
The ozone layer protects the Earth against most UVB coming from the sun. It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen.
What is ozone class 10th?
Ozone is a molecule formed by three atoms of oxygen. Oxygen is essential for all life processes whereas ozone is a deadly poison. At the higher levels of the atmosphere, it shields the surface of the earth from ultraviolet radiation of the sun which is highly dangerous to organisms as it can cause skin cancer.
How is ozone formed Class 10?
Ozone at the higher levels of the atmosphere is a product of UV radiation acting on oxygen (O2) molecule. The higher energy UV radiations split apart some molecular oxygen (O2) into free oxygen (O) atoms. These atoms then combine with the molecular oxygen to form ozone as shown.
What is ozone layer and its importance?
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.
What is ozone layer explain its importance?
The importance of ozone is defined by the fact that it protects the earth from harmful ultraviolet rays from the sun. The ozone layer is found in the upper regions of the stratosphere where it protects the earth from the harmful ultraviolet rays of the sun. These radiations can cause skin cancer in humans.
What is ozone hole Class 9?
Ozone holes can be termed as the depletion of the ozone layer which is present in the upper atmosphere i.e. stratosphere at the polar region of earth. The ozone hole doesn’t stop the radiation which is harmful to living things on earth and causes harmful effects such as health problems like skin cancer and eye damages.
What is ozone hole Class 6?
Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created.
Which is the correct definition of ozone?
Ozone (/ ˈ oʊ z oʊ n /), or trioxygen, is an inorganic molecule with the chemical formula O 3.It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 ().Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the
What is the difference between ozone and oxygen?
Differences in properties. Both diatomic ozone (O 2) and triatomic ozone (O 3) are made up of oxygen atoms but they have different chemical and physical properties.
What are facts about ozone?
– 1. Ozone was first discovered and isolated by the German-Swiss chemist Christian Friedrich Schönbein in 1839. – 2. Ozone is a pale blue gas with a distinctive pungent smell. – 4. One molecule of ozone consists of three oxygen atoms. – 5. – 6. – 7. – 8. – 9. – 10.
What does ozone mean in science?
