developed and what this collaboration means for our future. The envelope of gases surrounding the earth is called the atmosphere and it serves three critical functions: it provides life-giving oxygen, keeps the earth warm, and protects us from deadly ultraviolet (UV) radiation from the sun. Most of the atmosphere consists of nitrogen and oxygen (See Figure 1). But these gases do not keep us warm or protect the earth from UV rays. For these functions you have to turn to some of the trace gases found in

Implication of ozone in skin cancer rate This layer is vital to all living organisms (humans, animals, plants) by keeps them safe from genetic damage due UV radiation. Ozone absorbs 90% of UVB radiation which is show to have harmful effects on humans and an important role in skin cancer. The World Health Organization estimates that if there is a 10% decrease in stratospheric ozone, an additional 300,000 cases of NMSC, 4,500 cases of melanoma and between 1.6 and 1.75 million cataracts could result

Sunlight and shade can have effects on how the way turf grasses and weeds grow in lawns. Sunlight is make ultraviolet radiation, and certain types of UV radiation can cause harm to turf gasses by. Ultraviolet radiation all depends on what wavelengths the turf grasses can handle, the wavelengths average from 400-280nm (Huylenbroeck and Bockstaele, 2001). Turf grasses start to form adaptations to help survive in these conditions, by producing high amounts of chlorophyll, and having other characteristics

When asked ‘what is the heaviest organ in our body?’, most people would not think it is the skin. However, the truth is that the skin is the heaviest organ in our body, it is covering our entire body, and feels lightweight on our bodies. One of the reason why the skin is so heavy is that the skin is actually composed of three major layers, the epidermis, dermis, and the subcutaneous layers. The epidermis itself has 5 layers, the dead skin cells on the topmost layer, the stratum corneum, and the cells

Being capable of doing this would be beneficial to some people because it doesn’t take as long and sitting out in the sun. There is a controlled dosage of the ultraviolet rays to reassure the consumer does not receive a large amount of UV ray, these dosages should be spread out over several sessions. A great aspect of tanning is clients get privacy in their own booth. Weight, being too white, tan lines and uncomfortable

of ozone, and it acts like a sunshade for humans as it shields most of the harmful ultraviolet radiation that comes from the sun. The ultraviolet radiation also takes part in forming the ozone initially as the reaction of radiation separating the oxygen molecule made up of two atoms results in the separated oxygen molecules recombining with other oxygen molecules to form ozone. There are three types of Ultraviolet radiation and the three types differ in wavelength. UV-A radiation, emitted at 315-400

Sunscreen Hurting vs. Helping Have you ever thought when you were putting on sunscreen to prevent a sunburn, you could actually be causing something much more harmful? Sunscreen has been around since 1928 in order to prevent the harsh ultraviolet-rays from the sun burning our skin and thus preventing skin cancer. In contrast, studies have shown that sunscreen has caused many people to contract skin cancer due to harsh chemicals added into the products. Sunscreen also prevents your body from absorbing

of leaves and stem diameter were measured sporadically. After one month, the biomass of the seedlings was recorded. A starch analysis test was also performed. According to the results, the stem diameter of the experimental group exposed to the ultraviolet light was significantly smaller than that of the control group exposed to full spectrum light. The number of leaves, height, biomass and the starch production were
