Primary Cause of Combustion
Primary Cause of Combustion What gives life to planet Earth on the physical plane? Without air to breathe and water to drink the combustion in organisms on Earth cannot function. Air is water vapor (moisture that is water) and water is composed of hydrogen and oxygen. Combustion external to man for example is accomplished by burning a fuel after an ignition source sparks the flame. In the absence of air (that is 21% pure oxygen) the ignition of a flame will not occur.
