Earth's magnetic field the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that protects the Earth from harmful ultraviolet radiation. The Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds. Calculations of the loss of carbon dioxide from the atmosphere of Mars, resulting from scavenging of ions by the
Ultraviolet index numerical ranges, the recommendations for protection are as follows: When interpreting the UV Index and recommendations, be aware that: According to the U.S. Environmental Protection Agency, a helpful method to estimate the amount of UV radiation people are exposed to is by observing the length of their shadow. A taller shadow may mean a lower UV exposure while a shorter one could translate to exposure to higher levels of UV radiation. Ultraviolet index The ultraviolet index or UV Index is an international standard measurement of the strength of sunburn-producing ultraviolet (UV) radiation at a particular place and time. The scale
