3. Which of the following imaginary lines join places with same level of rainfalls?
[A] Isobaths lines
[B] Isohyets lines
[C] Isobar lines
[D] Contour lines
Show Answer
Correct Answer: B [Isohyets lines]
Notes:
An isohyet is also known as isohyetal line, and it is a line on a map which connects points that have the same amounts of precipitation in a given period or for a particular storm.
4. Which of the following is not favourable for the formation of deltas? (UPSC Prelims 1983)
[A] Calm winds
[B] Currents and tides
[C] Sheltered coast
[D] No large lakes in the river course
Show Answer
Correct Answer: B [Currents and tides]
Notes:
Conditions favourable for the formation of the Deltas:
• Active vertical and lateral erosion in the upper course of the river to provide extensive sediments to be eventually deposited as deltas.
• The sea adjoining the delta should be shallow or else the load will disappear in the deep waters.
Conditions not favourable for Delta formation:
• Tides
• Strong and regular currents
5. Isohyets are the lines drawn on a map connecting points having which of the following? (UPSC Prelims 1985)
[A] Equal temperature
[B] Equal height
[C] Equal atmospheric pressure
[D] Equal rainfall
Show Answer
Correct Answer: D [Equal rainfall]
Notes:
Isohyets is also known as isohyetal line and it is a line on a map which connects points that have the same amounts of precipitation in a given period or for a particular storm.
6. At a certain place, the Greenwich Mean Time is ahead by 12 hours. The place is located at which of the following locations? (UPSC Prelims 1986)
[A] 180°W of GMT
[B] 180°E of GMT
[C] 90°W of GMT
[D] 90°E of GMT
Show Answer
Correct Answer: A [180°W of GMT]
Notes:
A traveler going eastwards gains time from Greenwich until he reaches the meridian 180°E, when he will be 12 hours ahead of G.M.T.
Similarly, in going westwards, he loses 12 hours when he reaches 180°W. There is thus a total difference of 24 hours or a whole day between the two sides of the 180° meridian.
This is the International Date Line where the date changes by exactly one day when it is crossed. A traveler crossing the date line from east to west loses a day and while crossing the dateline from west to east he gains a day.
7. Which among the following is the study of depth of water bodies?
[A] Bathymetry
[B] Topography
[C] Oceanography
[D] Orology
Show Answer
Correct Answer: A [Bathymetry]
Notes:
Bathymetry is the measurement of the depth of water bodies such as oceans, seas etc.
8. Which among the following are gaseous planets?
[A] Mercury, Venus, Earth, Mars
[B] Mercury, Jupiter, Saturn, Uranus
[C] Saturn, Uranus, Neptune, Pluto
[D] Jupiter, Saturn, Uranus, Neptune
Show Answer
Correct Answer: D [Jupiter, Saturn, Uranus, Neptune]

9. Which planet among the following does not have a natural satellite?
[A] Saturn
[B] Mercury
[C] Neptune
[D] Uranus
Show Answer
