Question Discussion & Solution

 The correct answer is 1-A, 2-B, 3-C,4-D.

Additional Information

Some other important dams are-

The Indian Standard Time (IST) :

• The Indian Standard Time is calculated from 82°30’E meridian passing through Mirzapur.
• IST is plus 5.30 hours from the GMT. 
• It does not take into account daylight saving time along with other seasonal factors. India has only one timezone.

Greenwich Mean Time (GMT) : 

• Greenwich Mean Time (GMT), the name for the mean solar time of the longitude (0°) of the Royal Greenwich Observatory in England. 
• The meridian at this longitude is called the prime meridian or Greenwich meridian.

Important Points

International dateline :

• The prime meridian also helps establish the International Date Line.
• The Earth's longitude measures 360o, so the halfway point from the prime meridian is the 180 longitude line.
• The meridian at 180 longitudes is commonly known as the International Date Line.
• As you pass the International Date Line, you either add a day (going west) or subtract a day (going east.)

The correct answer is Rajasthan Dry Region.

Key Points

• Rajasthan Dry Region has been classified as ‘Western Dry Region’ among the 15 Agro-Climatic zones of India.
• In 1988 the Planning Commission came up with a growth strategy based on a holistic approach of area planning for long-term resource efficiency and sustainability.
  • During the late nineteen eighties, a consensus seemed to have been achieved on the primacy of topography for a regional division of India.
  • Based on this notion the Planning Commission proposed 15 agro-climatic zones, these have still existed wide variation in a geographical area, population density, soil types, and crops are grown.
  • To increase the degree of homogeneity in agro-climatic factors, these 15 zones were further sub-divided into 73 subzones based on more specific soil types, topography, climate, and cropping pattern characteristics.

The correct answer is C & D.

The correct answer is Bundi.

Key Points

• Aw or Tropical Humid Region:
  • ​The southern parts of Dungarpur, Jhalawar, and Banswara comes under the region.
  • The Winter season is arid and cool whereas summers experience scorching heat.
  • Rainfall also occurs mainly in the summer season.
  • Here arid Tropical grasslands and the Savanna region are found along with deciduous trees of Monsoon type.

​Additional Information

• A land-based classification of climatic zones, the Koppen classification system divides the earth into five major types, represented with the letters A, B, C, D, and E.
• Presently, the system utilizes both precipitation and temperature, as well as corresponding vegetation, to categorize biomes across the world.
• All zones except Zone B can be defined by temperature because the determining criteria for the vegetation in this zone are dryness, which falls under precipitation.
• Three types of climatic variation may be found within the Tropical Moist Climate region:
  • Af, or tropical wet climate, where precipitation occurs year-round.
    • Temperature variations are less than 3ºC.
    • Humidity is extremely high and the surface temperature results in the formation of cumulus and cumulonimbus clouds in the early afternoon time, daily.
    • This results in high rainfall.
  • Am, or tropical monsoon climate, where annual rainfall is similar to that of Af, but precipitation usually occurs within the 7-9 of the warmest months of the year.
    • During the rest of the year, there is less precipitation.
  • Aw, or the tropical wet and dry climate, also known as the savanna climate, where there is an extended dry season during the winter.
    • During the wet season, rainfall is less than 1000mm, occurring mainly in the summertime.
