Question Discussion & Solution

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.

• The Delhi–Mumbai Industrial Corridor Project is a planned industrial development project between Delhi and Mumbai.
• The DMIC project was launched in pursuance of an MOU signed between the Government of India and the Government of Japan in December 2006.
• It covers 6 states
• The investments will be spread across the 1,500 km long Western Dedicated Freight Corridor which will serve as the industrial corridor's transportation backbone.
• It includes 24 industrial regions, eight smart cities, two international airports, five power projects, two mass rapid transit systems, and two logistical hubs.
• The eight investment regions proposed to be developed in Phase I of DMIC are

1. Dadri - Noida - Ghaziabad (in Uttar Pradesh)
2. Manesar - Bawal (in Haryana) 
3. Khushkhera - Bhiwadi - Neemrana and Jodhpur - Pali - Marwar (in Rajasthan) 
4. Pithampur - Dhar - Mhow (in Madhya Pradesh)
5. Ahmedabad - Dholera
6. Special Investment Region (in Gujarat)-Gate
7. Aurangabad Industrial City (AURIC)
8. Dighi Port Industrial Area in Maharashtra.

Key Points 

• The project has received a major boost from India and Japan, due to an agreement to set up a project development fund with an initial size of ₹1,000 crore
• The Japanese and Indian governments are likely to contribute equally. 

The correct answer is Maharashtra.

Key Points

• Rajasthan is a state in the northwestern part of India bordering Punjab, Haryana, New Delhi, Madhya Pradesh and Gujarat.
  • The state also shares a border with the neighboring country of Pakistan.
  • Among the given options, Maharashtra is the state of India with which Rajasthan does not share its border.​ 

Additional Information 

• The Tropic of Cancer passes through eight states in India:
  • Mizoram (Champhai)
  • Tripura (Udaipur)
  • West Bengal (Krishnanagar)
  • Jharkhand (Lohardaga)
  • Chhattisgarh (Sonhat)
  • Madhya Pradesh (Shajapur)
  • Rajasthan (Kalinjarh)
  • Gujarat (Jasdan)
• The Tropic of Cancer does not pass through Orissa.
• Tropic of Cancer passes through the middle part of India. 
• From the extends south to north, the mainland of India extends between 8°4’N and 37°6’N latitudes.
• From the other extends west to east, India extends between 68°7’E and 97°25’E longitudes.
• Due to the great longitudinal extent and difference of about 29°, ta wide differences in local time of places located at two extreme points of the country.
• The difference between these two points would be approximately two hours.

The correct answer is A - i, B - ii, C - iii, D - iv.

Key Points

•  Aridisols soil
  • These are CaCO₃-containing soils of arid regions that exhibit subsurface horizon development.
  • They are characterized by being dry most of the year and limited leaching.
  • They contain subsurface horizons in which clays, calcium carbonate, silica, salts, and/or gypsum have accumulated.
• Inceptisols soil
  • It exhibits minimal horizon development.
  • They are more developed than Entisols, but still lack the features that are characteristic of other soil orders.
  • A sizable percentage of Inceptisols are found in mountainous areas and are used for forestry, recreation, and watershed.
  • They occur in cool to very warm and humid to subhumid climates, from the arctic to the tropics.
  • They are found in Semi-arid and humid regions.
• Alfisols soil
  • They are moderately leached soils that have relatively high native fertility.
  • These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated.
  • They are primarily found in temperate humid and subhumid regions of the world.
• Vertisols
  • They are clayey soils that have deep, wide cracks for some time during the year.
  • They shrink as they dry and swell as they become moist.
  • The natural vegetation is predominantly grass, savanna, open forest, or desert shrub.
  • They are found in Humid and super-humid regions.
