Answer:
Carbon dioxide and water vapour concentrations will lead to change in temperatures.
Explanation:
- Most of the common volcanic gases include carbon dioxide, sulphur dioxide and hydrogen sulphide along with small quantities of volatile compound and elements present such as hydrogen, helium and chloride etc.
- The carbon dioxide and water vapour alter the temperature During the experiment the concentration of carbon dioxide goes up and the temperature goes down. Thus volcanic eruption often leads to global cooling.
The trolleys have been reduced over the last decades, after their initial increase as a public transportation, when new and better ways were discovered/produced for transport, their decline has started.
The buses since their invention, had grown in number and became a very important part of every city's public transportation, and still are.
The rapid transit is the most recent one of the mentioned in here. It's popularity has grown, number increased, and is very practical because it is not causing traffic mess. It is very important transport asset nowadays and makes lives of millions of people much easier.
Nitrogen (78%), Oxygen (21%), Argon (0.9%), and the remaining 0.1% consists of traces of neon, krypton xenon, carbon dioxide, nitrogen oxides, and traces of others. so Nitrogen is the greatest. I hope this helps :)
