Heating the Atmosphere A. What Happens to Incoming Solar Radiation? When radiation strikes an object, 3 things happen: some of the energy is absorbed by the object (converted to heat+temperature rises), some substances (water+air) are transparent to certain radiation wavelengths + transmit energy, and some radiation is bounced off the object without absorption/transmission. Reflection + scattering are responsible for redirected solar radiation. Out of the total solar radiation from the sun, 50% is absorbed by the land/sea, 20% is absorbed by the atmosphere/clouds, 5% is reflected from the land/sea surface, 5% is backscattered to space by the atmosphere, 20% is reflected by the clouds (in total, 30% is lost to space by reflection/scattering). B. Reflection and Scattering

Michael Treacy 3/3/2010 Pd. 3 Ozone Hole @ TD 1. What is the Ozone and why do we need it in our atmosphere to have a healthier planet? The Ozone is the Gas O3. This gas is located in the Stratosphere and absorbs UV Rays. We need the ozone in our atmosphere because it absorbs 98% of the UV Rays. Without the ozone to filter all these UV Rays many animals would have medical / health problems. 2. Describe how the ozone protects us. The ozone protects us by filtering out and absorbing most of the UV Rays before they reach the earth. Most of the Rays are biologically harmful and know to damage tissues and cells. 3. How is a chlorine atom harmful to the ozone in the stratosphere?
