The ozone (or ozone layer) is a natural gas layer in the upper atmosphere. It protects people and other living creatures from ultraviolet (UV) radiation. The ozone layer has been affected by many human activities. To test your knowledge about the ozone layer, take the quiz below.
The ozone layer is related to which of the following spheres?
What is the ozone layer?
The concentration of ozone molecules within the stratosphere is called the ozone layer. The ozone layer contains approximately 90 percent of the Earth’s ozone. The troposphere is the layer of Earth’s atmosphere around us. The stratosphere is the next layer higher and extends approximately 6 to 31 miles (10 to 50 km) above the Earth’s surface.
Is the ozone layer going to recover?
By 2050, the ozone layer will return to its average level. The world must adhere to the Montreal Protocol. Delays in ending the production or use of ozone-depleting substances can cause further damage to the ozone layer and may prolong its recovery.
