Answer 1

1.Utilities contribute roughly 40% of CO2 in the atmosphere. How is CO₂ formed during the generation of electicity?

Ans: Power generation requires the use of coal, natural gas- in case of thermal power station and water - incase of hydroelectricity generation.

The generation of electriciy by means of natural gas requires the process called combustion. The combustion of natural gas produces CO₂, H₂O and lot of energy. Natural gas mostly contains methane (CH₄)

CH₄ + 2O₂ CO₂ + 2H₂O

The water released is in the form of steam and is used in the rotation of turbines which in turn acts on generator to produce electricity.

2.What is the difference between "climate" and "weather"?

Ans: The major difference between weather and climate is that weather is the short term estimate of how the atomosphere is behaving. For example change in weather from minute to minute or hour to hour or in a month.

But climate is the behaviour of atmosphere over a period of months, For example, it include several days in a weather make climate. Summer is when several days of hot atmosphere combined together to make climate.
