What is ozone layer in simple words?
What is ozone layer in simple words?
The ozone layer is a thin part of the Earth’s atmosphere that absorbs almost all of the sun’s harmful ultraviolet light. “Ozone holes” are popular names for areas of damage to the ozone layer. Ozone layer damage is more like a really thin patch than a hole.
What is the ozone layer and why is it important?
The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
What is ozone layer Class 7?
Ozone is a layer in the earth’s stratosphere which acts as a shield absorbing ultraviolet radiation from the sun.
Why is the ozone layer important to life on Earth?
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.
Where is ozone bad?
In the troposphere, near the Earth’s surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is ‘bad’ as it is harmful to breathe and also damages vegetation.
How do you explain the ozone layer to a child?
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.
What would happen if there is no ozone layer?
Without the Ozone layer in place, radiation from the sun would reach earth directly, damaging the DNA of plants and animals (Including humans). The intensity of the sun’s radiation would make photosynthesis (a process by which plants convert light energy into chemical energy to fuel their growth) impossible.
How the ozone layer was formed?
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.
What would happen if we had no ozone layer?
This natural sunscreen, known as Earth’s ozone layer, absorbs and blocks the majority of the sun’s UV radiation. Without this barrier in place, all of the radiation would reach Earth, damaging the DNA of plants and animals, like us humans. Without plants, the food chain would collapse.
What is the main function of ozone layer?
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.
