The ozone layer began shielding Earth from ultraviolet rays approximately 2 billion years ago when oxygen levels in the atmosphere increased due to the rise of photosynthetic organisms. The ozone layer helps to absorb the majority of the Sun's harmful UV radiation, protecting life on Earth from its damaging effects.

When did the shielding of earth from ultraviolet rays begin?
The shielding of Earth from ultraviolet rays began when the ozone layer formed around 2.4 billion years ago. This layer absorbs and scatters a significant portion of the Sun's ultraviolet radiation, protecting life on Earth from its harmful effects.
What is the important gas in the atmosphere that absorbs ultraviolet radiation from the sun?
Ozone is the important gas in the atmosphere that absorbs ultraviolet radiation from the sun. It forms a protective layer in the stratosphere, shielding the Earth's surface from harmful UV rays.
How many ultraviolet rays are there?
There are three main types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA and UVB are the ones that reach the Earth's surface, while UVC is mostly absorbed by the Earth's atmosphere.
What is the layer that protect us from meteors and ultra violet rays from the sun?
The ozone layer is the layer in Earth's stratosphere that protects us from harmful ultraviolet (UV) rays from the sun. It absorbs most of the sun's UV radiation, shielding the Earth's surface and living organisms from its harmful effects.
Is ozone layer protect them from excessive ultraviolet rays of the sun?
Yes, the ozone layer helps to protect the Earth from excessive ultraviolet (UV) rays of the sun by absorbing the majority of the harmful UV radiation. This shielding effect is crucial for safeguarding living organisms from the damaging impacts of UV radiation, such as skin cancer and cataracts.

How do infrared rays and ultraviolet rays affect Earth?
global warming i guess?!

What is the atmospheric layer that protects earth for ultraviolet rays?
The ozone layer protects Earth from ultraviolet (UV) rays by absorbing most of the UV radiation from the sun. It is located in the lower portion of the stratosphere, approximately 10 to 30 kilometers above the Earth's surface. The ozone layer plays a crucial role in shielding living organisms from harmful UV radiation.
Which layer protect earth from ultraviolet rays of the sun?
Ozone layer protects the earth from UV rays. These are fatal for life on earth.
Does ultraviolet radiation come to the earth?
Yes, It comes from the suns rays to the earth
What is the shield that protects the earth from ultraviolet rays from the sun?
ozonosphere
