in the little bits of radiation from the sun hitting the earth. The ozone layer protects the earth from harmful ultraviolet B radiation that comes from the sun. The Chapman cycle is natural cycle which occurs in the stratosphere with a constant interaction between oxygen molecules and ultraviolet ray. This process is a cycle, because it is a constant switch between different molecules of oxygen. The ozone layer itself is created during the cycle it is made when ultraviolet rays react with oxygen
For instance ultraviolet light affects many of the human organism parts and many diseases, but at the same time it does have disadvantages. Those harms are mainly related to biology; when exposing to overdose of UV-B&A we can notice that this will damage surface eyes and cells and it might cause cancer disease, although we have sunscreens that protect us from UV-B but still we have the free radical damage cause by the UV-A, some pretend that dark skin is in the safe side and protected
rays, a person's skin begins to prematurely age, it can damage a person's eyes, and it can cause melanoma or benign cancer. The chances of those happening are decreased if people are better educated about the dangers and there are better rules put in place. A person's skin is her largest organ, so she needs to do the best she can to protect it (Skin). In tanning beds, one does not get the usual UV-A and UV-B rays. A person tanning in a tanning bed receives ultraviolet radiation that is put off by
is it? Sun tanning is when a person exposes themselves to the sun in order to achieve a browner skin colour (become tanned). According to skincancer.org, “The most dangerous form of skin cancer, these cancerous growths develop when unrepaired DNA damage to skin cells (most often caused by ultraviolet radiation from sunshine or tanning beds) triggers mutations (genetic defects) that lead the skin cells to multiply rapidly and form malignant tumors. These tumors originate in the pigment-producing
Ultraviolet radiation - (UV) Ultraviolet (UV) radiation is an invisible electromagnetic radiation with wavelength from 10 to 400 nanometers (nm) which are just shorter than those of ordinary, visible violet light but longer than x-rays. Naturally, about 10% of the sun light output is in the form of UV radiation which is also artificially produced by several sources, such as during electric (arc) welding, mercury-vapor lamps, tanning booths and halogen lights. Depending on the wavelength range of
albinism (1). Albinism is caused by the mutations in the genes that provide instructions for making proteins, which are involved for producing melanin, the pigment that provides the colour to the eyes, hair and skin. Melanin absorbs ultraviolet (UV) light from the sun to protect the skin. When these genes are altered,
activities emit more carbon dioxide in the atmosphere which increases global warmth of Earth. Greenhouse gases tends to trap heat from many sources like sun, burning coal, burning fuels and avoid them to escape back to the atmosphere. Global warming may cause rising sea levels due to the melting of the polar ice caps, health disorders and invites so many natural disasters such as occurrence of storms. Global warming is a process which ignores national boundaries so it is difficult to determine who is
Was the Moon Landing a Hoax? Forget about it, NASA was known worldwide for their great accomplishment. Landing on the moon! The day was July 20, 1969 and United States were the first and only country to land on the moon, and everyone was filled with much gratitude. We won the space race with the Soviets and other countries as Neil Armstrong and Edwin "Buzz" Aldrin as our witnesses. Armstrong famously said, “That’s one small step for man, one giant leap for mankind.” The Apollo 11 mission occurred
