What is the component of ozone layer?
The ozone molecules in the upper atmosphere (stratosphere) and the lower atmosphere (troposphere) are chemically identical, because they all consist of three oxygen atoms and have the chemical formula O3.
In which layer is ozone helpful?
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.
Why is the ozone layer an important component of the atmosphere?
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 is ozone layer formed in stratosphere?
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.
What role does ozone play in the stratosphere?
High level or “good” ozone occurs in the stratosphere and accounts for the vast majority of atmospheric ozone. The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth’s surface and harming living organisms.
What is the importance of the ozone layer found on the boundary of the troposphere and stratosphere?
The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat.
How does ozone layer protect the earth?
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.
Is ozone a major component of the atmosphere?
Ozone is also a small but very important component of the atmosphere. Ozone is made up of three oxygen molecules and is what protects us from harmful UV radiation coming from the sun. Ozone absorbs this radiation, blocking most of it from reaching us on the ground.
What is the most important component of the atmosphere?
The table indicates that nitrogen and oxygen are the main components of the atmosphere by volume. Together these two gases make up approximately 99% of the dry atmosphere. Both of these gases have very important associations with life.
How is ozone produced in stratosphere?
Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the second step, each of these highly reactive atoms combines with an oxygen molecule to produce an ozone molecule (O3).
Is the ozone layer between the troposphere and stratosphere?
Ozone is a gas that is naturally present in our atmosphere. The remaining ozone (about 90%) resides in the stratosphere between the top of the troposphere and about 50 kilometers (31 miles) altitude. The large amount of ozone in the stratosphere is often referred to as the “ozone layer.”
Why is the ozone layer important quizlet?
Why is the ozone layer important? This layer acts as a filter to prevent too much of the harmful ultraviolet light in sunlight from reaching earth.
