Question 1

When there is noon at IST meridian, people in another place of the Earth are taking their 6 O' clock morning tea. The longitude of the place is ______.

Accepted Answer

If the time of the concerned place is 6 hours behind Indian Standard Time (IST), which itself is 5.5 hours ahead of Greenwich Mean Time (GMT), it means that it is located to the west of Prime Meridian, i.e. 0 degrees meridian. A difference of 15 degrees in longitude represents 1 hour of difference. This means that the given location is located 7.5 (15 divided by 2) degrees west of the Prime Meridian, i.e 7 degrees and 30 minutes W.

Question 2

Which of the following statements is the reason for 'Seasons' on the surface of the Earth?

Accepted Answer

The earth has an axial tilt of 23.5 degrees which means that its rotation axis is inclined to its orbital axis at an angle of 23.5 degrees. This causes one pole of the earth to be directed more towards the Sun on one side of the orbit, and the other pole on the other side. This is the reason for occurrence of 'seasons' on earth.

Question 3

What is the difference between asteroids and comets?
(1) Asteroids are small rocky planetoids, while comets are formed of frozen gases held together by rocky and metallic material.
(2) Asteroids are found mostly between the orbits of Jupiter and Mars, while comets are found mostly between Venus and Mercury.
(3) Comets show a perceptible glowing tail, while asteroids do not.
Which of the statements given above is/are correct?

Accepted Answer

Difference between asteroids and comets lies mainly in their composition. Both were formed during the early phase of the solar system. Asteroids consist mainly of rocky and metallic material, while comets comprise if ice, frozen gases, dust and rocky and metallic material.Asteroids are found nearer to the Sun while comets are found farther from the Sun as the heat can melt away comet's ice. In fact, when a comet approaches the Sun, it starts losing its ice because of the Sun's heat as a result of which a perceptible glowing tail can be seen.

Question 6

Which of the following statements concerning Mediterranean climatic region are correct?
1. It is found in the latitude range $3 0^{o} t o 4 5^{o}$ northern and southern hemisphere
2. Mediterranean climate experiences extreme temperature conditions
3. In Mediterranean climate, rainfall occurs mainly during summer season
4. In Mediterranean climate, rainfall is mainly due to Westerlies
Select the correct answer using the code given below:

Accepted Answer

The Mediterranean climate is usually characterized by rainy winters and dry, warm to hot summers. The regions are between roughly 30 and 45 degrees north and south of the equator. The weather in the region is very dry, stable, and pleasant. Mediterranean climates receive around 20 inches of annual (yearly) rainfall. The main controlling factor over the characteristics of the dry summer subtropical climate is the alternating influence of the subtropical high in summer and Westerlies during the winter.

Question 9

South Pacific island nation Samoa, positioned to the East of the International Date Line, on May 2011 decided to forego a day and shift to the time zone on its West. The reason for this shifting is to ________.

Accepted Answer

Samoa decided to shift to the west of the International Date Line in order to come in the same time zone as Australia, New Zealand and Eastern Asia which would have facilitated trade with these nations and thus would have been in the economic interests of Samoa.
