how much solar radiation does the atmosphere protect the earth's surface from?
313205
About 26% of the sun's energy is reflected or scattered back into space by clouds and particulates in the atmosphere 34. Another 18% of solar energy is absorbed in the atmosphere. Ozone absorbs ultraviolet radiation, while carbon dioxide and water vapor can absorb infrared radiation 34.

Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself. About 23% of incoming energy is absorbed in the atmosphere by atmospheric gases, dust, and other particles.

The atmosphere protects us from exposure to higher energy radiation that can be harmful to life – i.e. X-Ray and Gamma Rays. As the energy passes through the atmosphere, it interacts with the molecules and particles present in the atmosphere.

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. ... The level of UVR from the sun measured at the Earth's surface varies linearly with latitude.

The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.

The greenhouse gases in the atmosphere absorb the sun's heat, radiated from the surface of the earth, and keep the planet warm enough for life. It is called a blanket because it acts like a blanket to earth. It protects the Earth like a blanket protects us from cold.

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Earth's atmosphere. Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

It is mostly gas, which we call "air," and it is held in place because of Earth's gravity. Some of the gas is oxygen. Many living things, including humans, need oxygen to breathe. The gases in the atmosphere also protect us from harmful solar rays, but not completely, which is why we often wear sunscreen.

The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The Sun is much hotter than the Earth and it gives off rays of light energy that travel through the atmosphere and reach the Earth's surface.
901192
The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and warming the surface through heat retention (the greenhouse effect ). The atmosphere is further classified into multiple layers by temperature, which include the thermosphere, the mesosphere, the stratosphere, and the troposphere.

It's a good thing these gases are there. Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting like a duvet wrapped around the planet.
1038411
The atmosphere is heated by radiant energy from the Sun -‐ solar energy. Lots of different kinds of rays are sent out by the Sun, but the most important ones are visible light and invisible light called infrared radiation. ... Visible light is absorbed by Earth's surface. The land and seas warm up.

The atmosphere helps to protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays. The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.

How does the Atmosphere protect life on Earth? The Atmosphere protects and contols the temperature on the surface of the Earth. It absorbs or reflects the radiation from the sun; and the "Greenhouse Effect" helps to control the temperature on Earth.

The maximum intensity of the sun's output of radiation is in the visible light region. At the top of the atmosphere, approximately 7% of the radiation is in the ultraviolet, 41% in the visible, and 52% in the infrared.
