'The principle of superposition states that when two disturbance occupy the same space at the same time the resulting disturbance is the sum of two disturbances.'
Explanation:
if two pulses are moving towards each other in the same medium and are not disturb by any external force they will approach each other and the point which will be the the sum of their individual displacement or more precisely the point of superposition of both pulses either constructive or destructive depending on the conditions given

Answer:
Earth's first atmosphere 4.6 billion years ago was most likely comprised of hydrogen and helium (two most abundant gases found in the universe!)
Through the process of outgassing, the outpouring of gases from the earth's interior, many other gases were injected into the atmosphere. These include:
-water vapor (produced rain - rivers, lakes, oceans)
-carbon dioxide
-nitrogen
As outgassing occurred over a period of millions of years, the atmosphere evolved to its current state
