2. Question
Which one of the following processes is related to the formation or modification of the present atmosphere?
CorrectAns:- d) All of the above
Explanation:-
The present composition of earth’s atmosphere is chiefly contributed by nitrogen and oxygen.
The first stage is marked by the loss of primordial atmosphere. In the second stage, the hot interior of the earth contributed to the evolution of the atmosphere. Finally, the composition of the atmosphere was modified by the living world through the process of photosynthesis.
The early atmosphere, with hydrogen and helium, is supposed to have been stripped off as a result of the solar winds. During the cooling of the earth, gases and water vapour were released from the interior solid earth. The process through which the gases were outpoured from the interior is called degassing.
Continuous volcanic eruptions contributed water vapour and gases to the atmosphere.IncorrectAns:- d) All of the above

4. Question
Consider the following statements regarding the Standard Time Zones and choose not correct one?
CorrectAns;- b) Every country has only one Standard Meridian Time.
Explanation:-
As question asked to choose not correct , statement b is not correct
The number of time zones a country practices mostly depends on the size of the country .
For example, it’s impossible for a country as huge as Russia with the area of 17.1 million km² to process on only one time zone –this might create a problem of day-night difference within the same country .
So Russia has 11 time zones and USA has 6 time zones.
However there are certain exceptions like china which works on only one time zone despite its size.
Indian Standard Time is calculated on the basis of 82.58° E longitude and its uniform all around the country.IncorrectAns;- b) Every country has only one Standard Meridian Time.

5. Question
If the International Date Line was a straight line, which of the following islands would have experienced a two-date problem within the same time zone?
CorrectAns:- d) All of the above
Explanation:-
The International Date Line is an imaginary line of longitude on the Earth’s surface located at about 180 degrees east (or west) of the Greenwich Meridian and marks the divide where the date changes by one day.
It makes some deviations from the 180-degree meridian to avoid dividing countries in two, especially in the Polynesia region.
The time difference between either sides of the International Date Line is not always exactly 24 hours because of local time zone variations.
If you travel around the world, changing standard time by one hour each time you enter a new time zone, then a complete circuit would mean that you adjusted your clock or watch time by 24 hours.
This would lead to a difference of one day between the date on your clock and the real calendar date.
To avoid this, countries are on either side of the International Date Line which runs down the middle of the Pacific Ocean. If you cross the date line moving east, you subtract a day, whereas if you are moving west you add a day.IncorrectAns:- d) All of the above
