- The OZONE LAYER which lies in Stratosphere (16 to 48 kilometers above earth's surface) protects us from harmful UV radiation. Ozone layer help us by trapping harmful radiation from the sun. Ultraviolet(UV) rays are harmful rays which come from the sun. Ozone layer is made up of #O_3# or three atom of oxygen. When UV rays of 230 to 320 nm hit the ozone layer, #O_3# absorbs its energy and gets converted into #O_2# & then #O#.

- Radiation from space is constantly hitting the Earth. Radiation from space is called cosmic radiation. About five percent of the average annual radiation exposure for people in the United States comes from outer space. Earth’s atmosphere also shields us from most of the cosmic radiation that comes our way.

Topic Test Topic Test Review Explain the role of the ozone layer in sustaining life on Earth. The ozone layer helps regulate the Earth's temperature by absorbing a large percentage of the UV radiation entering the atmosphere. This protects living organisms from exposure to large amounts of UV radiation, maintains livable climates, and regulates the amount of harmful ground-level ozone. Compare the health and environmental risks associated with ground-level ozone to the health and environmental risks associated with ozone layer depletion.

Survival Directory Protecting Yourself from EMP. (1) the equipment inside the box does NOT touch the metal container (plastic, wadded paper, or cardboard can all be used to insulate it from the metal) and (2) the metal shield is continuous without any gaps between pieces or extra-large holes in it.© 1989 by Duncan Long EMP.The letters spell burnt out computers and other electrical systems and perhaps even a return to the dark ages if it were to mark the beginning of a nuclear war. But it doesn't need to be that way.n such a case, the gamma radiation released during the flash cycle of the weapon would react with the upper layer of the earth's atmosphere and strip electrons free from the air molecules, producing electromagnetic radiation similar to broad-band radio waves (10 kHz-100 MHz) in the process.

- UV Protection. Protecting Your Eyes from Solar Radiation. The sun supports life on our planet, but its life-giving rays also pose dangers. The sun's primary danger is in the form of ultraviolet (UV) radiation. Artificial sources, like welding machines, tanning beds and lasers, can also produce UV radiation.

The ozone layer and its effect on ultraviolet light The ozone layer and its effect on ultraviolet light. The Earth is surrounded by a thick atmosphere which provides us with the air we beathe, keeps the planet warm and also protects us from harmful radiation from space. One of the most important types of damaging radiation is ultra violet radiation from the Sun. The part of the atmosphere that filters out a lot of the ultra violet radiation is called the ozone layer – a region of the atmosphere between about 15 and 40 km above the Earth's surface. The ultra violet radiation from the Sun is divided into three regions depending on the wavelength of the radiation.

DOES THE ozone layer protect us from meteors? The ozone layer protects us from UV radiation. The gases in our atmosphere is what protects us from meteors, due to frictional forces as a meteor slams into our atmosphere at high speeds. Certain chemicals we put into the air can deplete the ozone, such as CFC's.

Ozone Layer Protection Ozone Layer Protection. Welcome to EPA's ozone layer protection web area. The ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation. The emission of ozone depleting substances has been damaging the ozone layer. But through domestic and international action, the ozone layer is healing and should fully recover by about 2065.

- The Ozone Hole For nearly a billion years, ozone molecules in the atmosphere have protected life on Earth from the effects of ultraviolet rays. The ozone layer resides in the stratosphere and surrounds the entire Earth. UV-B radiation (280- to 315- nanometer (nm) wavelength) from the Sun is partially absorbed in this layer. As a result, the amount of UV-B reaching Earth s surface is greatly reduced.

How does atmosphere protect the living from harmful radiation ? All living organisms on the earth are protected from the harmful radiation coming from the sun by the ozone gas present in the stratosphere. Ozone gas is formed by the action of sunlight only oxygen of the air in the atmosphere.

- How ozone protects us Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. Without the layer of ozone in the atmosphere, it would be very difficult for anything to survive on the surface. (Think of a very bad sunburn, only much worse!) Plants cannot live and grow in heavy ultraviolet radiation, nor can the plankton that serve as food for most of the ocean life. The ozone layer acts as a shield to absorb the UV rays, and keep them from doing damage at the Earth's surface.

How does Earth keep its atmosphere? Still, all in all, Earth’s atmosphere is here to stay. And that’s a good thing because our atmosphere protects life on Earth in many ways. It absorbs harmful ultraviolet radiation from the sun, helps keep Earth’s surface warm via the greenhouse effect, and reduces temperature extremes between day and night. Yay atmosphere! It keeps Earth livable. So, thanks to gravity, although some of Earth’s atmosphere is escaping to space, most is staying here.

- The stratospheric ozone layer, centered at about 20 km above the surface of the Earth (Figure 10-1), protects life on Earth by absorbing UV radiation from the Sun. In this chapter we examine the mechanisms controlling the abundance of ozone in the stratosphere and the effect of human influence.

What does the ozone layer protect us from? The ozone layer protects us from the sun's powerful rays. The Ozone layer protects us from the ultra violet rays from the sunlight which can cause skin cancers and eye cataracts, as well as damaging crops like rice and wheat.

Protecting Against Exposure γ GAMMA: To reduce typical gamma rays by a factor of a billion, thicknesses of shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays. The higher the energy of the gamma ray, the thicker the shield must be.

How does ozone protect us? Protects us from harmful UVB and UVC radiation. In the Stratosphere the ozone layer absorbs harmful UVB and UVC radiation, however allowing UVA (and small amount of UVB), for photosynthesis and vitamin D, which are both essential for life. Every time an ozone reacts with UV light, it absorbs it.

What level of the atmosphere bounces radio waves back to earth and protects us from radiation from the sun?   The Ionisphere bounces radio waves back to earth and regulates the amount of radiation that gets to the lower atmospheres. It all depends on the Sun's activity. The stra … tosphere is what actually protects us from the UV rays of the sun. The stratosphere creates the ozone layer to keep the UV rays out.
