The upper stratospheric layer contains ozone, which is produced when the ultra violet radiations strike the dioxygen (O2) molecules from the earth's atmosphere. The UV rays split a dioxygen molecule into a free oxygen atom (O). read more
The upper stratospheric layer contains ozone, which is produced when the ultra violet radiations strike the dioxygen (O2) molecules from the earth's atmosphere. The UV rays split a dioxygen molecule into a free oxygen atom (O). This oxygen atom then combines with another oxygen molecule from the atmosphere to form an ozone molecule (O3). read more
Without the atmosphere that protects the Earth, humans, animals and all plant life would not be able to survive. The atmosphere works to hold oxygen in the area around the earth. Humans and most animals are dependent on oxygen. read more
Most of the ozone on Earth accumulates in the stratosphere, a layer of the atmosphere between 15 and 30 kilometers above the Earth's surface. The ozone layer prevents the heat energy reflected by the Earth's surface from being re-radiated into space. This process traps heat on the Earth and keeps it warm. read more
