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 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.

Ocean Current:

• An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
• Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements.
• An ocean current flows for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth’s regions.

Key Points

Types of current:

• Warm Currents: Warm ocean currents flow away from the equatorial region on the western side of ocean basins. The Gulf Stream in the North Atlantic and the Kuroshio Current in the North Pacific are examples of warm currents. Of all the warm currents, the Gulf Stream has been studied most extensively.
• Cold Currents: Cold currents flow toward the equator on the eastern side of ocean basins. Examples of cold ocean currents include the Canary Current in the North Atlantic, the California Current in the North Pacific, and the Benguela Current in the South Atlantic.

Location of the ocean current:

The correct answer A-(iv), B-(i), C-(iii), D-(ii)
