What is the significance of ozone layer?

What is the significance 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.

What is the ionosphere layer?

The ionosphere is where Earth’s atmosphere meets space The ionosphere stretches roughly 50 to 400 miles above Earth’s surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth’s lower atmosphere — where we live and breathe — and the vacuum of space.

What is the importance of the ionosphere within the thermosphere?

The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.

Is ozone an ionosphere?

The concentration of ozone is gradually reducing. As the content of ozone is highest in ionosphere and the air itself being very thin, the depletion is negligible in ionosphere. But in mesosphere and stratosphere the air is thicker and ozone content is less.

What is the significance of ozone layer write a short note on ozone layer depletion?

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 phenomenon can be seen only in the ionosphere?

The colorful curtains of light, known as the aurora borealis and aurora australis, respectively, hang about 620 miles (1,000 km) above the Earth’s surface. The auroras glow green-yellow when ions strike oxygen particles in the lower ionosphere.

In which layer of the atmosphere the ionosphere is found what is its importance?

The Thermosphere and Ionosphere The region of the atmosphere above about 80 km is also caused the “ionosphere”, since the energetic solar radiation knocks electrons off molecules and atoms, turning them into “ions” with a positive charge.

Why ionosphere is so called?

The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.

What is the importance of ozone layer Class 10?

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.
