The ozone layer is a thin concentration of ozone gas that exists in the stratosphere. The ozone layer has been damaged in the past due to human production of chlorofluorocarbons (CFCs) and other fluorinated gases. However, due to a ban on these chemicals, the ozone layer is regenerating....
The ozone layer is a section of the Earth's atmosphere filled with molecules that block harmful ultraviolet radiation from reaching the surface. In 1985, scientists from the British Antarctic Survey discovered that ozone concentrations over the South Pole were decreasing at an alarming rate, creating...
However, this thin filter is enough to keep us safe and block most of the ultraviolet radiation coming from the sun. The smaller is the wavelength of ultraviolet light and can cause more damage to life, but is also more easily absorbed by the ozone layer. The problem lays at the places ...
People once thought of tile languages of backward groups as undeveloped forms of speech, consisting largely of rough and simple sounds. It is possible that language in general began as a series of simple sounds. But it is a fact established by the study of "backward" languages that no spoken...
