The Rimmer model for the development of land transport system in less developed economics was proposed in which of the following years ?
Answer (Detailed Solution Below)
Geography MCQ Question 20 Detailed Solution
Download Solution PDF- Transport network models comprise of frameworks for the transportation infrastructure, and their development is based on a number of intrinsic contributory factors of which environmental features are a critical part. Transport network models are thus used as frameworks to formulate systems.
- The development of transport networks utilizes several models for understanding the mode of development of the system. Such models can be quite specific regarding the mode of development of the transport networks they study. Some models lay a priority on spatial dimensions, some on modes of transport, while other approaches lay emphasis on a factor, such as analyzing the economic aspects of transport networks in their development. Among Transport Development Models, some notable models are as follows –
-
Rimmer in 1977 presented a four phase model for the analysis of interrelated development of transport networks between developed countries and third world nations. The model traces the impact of colonialism on the development of transport systems in these nations.
-
The first phase begins with no links between the two, with more badly made roads, a limited amount of tracks for trains, etc with a socio-economic order with restricted means and ends.
-
The early colonial phase is the second phase, and consists of exploration of the regions by colonial powers through sea routes, beginning with seafaring trade and limited settlements on these nations by colonial powers.
-
The third phase occurs post colonization, and here the colonial powers engage in laying their basic infrastructure such as roads and railways along with radical changes in the political and economic organization of Third World nations.
The last phase in this model is the neo-colonial stage, involving diversification and modernization of the transport systems. These transport networks were aimed at resource extraction from colonized nations by the colonial powers.
The metallic minerals that occur as alluvial deposits in flood plains or valleys are known as _______.
Answer (Detailed Solution Below)
Geography MCQ Question 21 Detailed Solution
Download Solution PDFThe correct answer is placer deposits.
Key Points
- Placer deposits, or "placers," are collections of valuable minerals that have been naturally concentrated in overburden, stream sediments, or beach materials.
- The minerals are liberated from solid rock by mechanical and chemical weathering.
- Then they are typically carried to their final resting place by water or wind action.
- Large minerals or minerals with a higher density are deposited when the water's velocity slows.
- Heavy minerals, such as gold, diamond, Ti, Cr, Sn, and magnetite, will be concentrated in locations where water current velocity is low because they will be deposited at a faster rate than low density minerals, such as quartz.
- Placer deposits have a specific gravity above 2.58.
Additional Information
- Polymetallic nodules:
- Manganese nodules, also known as polymetallic nodules, are mineral concretions on the ocean floor that are made of a central core and concentric layers of iron and manganese hydroxides.
- They contain four essential battery metals: cobalt, nickel, copper and manganese, in a single ore.
- Vein deposits:
- Veins are mineral deposits that develop when fresh mineral material fills a pre-existing fissure or crack inside a host rock. Aqueous solutions are often circulated to perform mineral deposition.
______ are longitudinal valleys formed as a result of folding when Eurasian plates and Indian plates collided.
Answer (Detailed Solution Below)
Geography MCQ Question 22 Detailed Solution
Download Solution PDFThe correct answer is Duns.
Key Points
- Duns are longitudinal valleys formed as a result of folding when Eurasian plates and Indian plates collided.
- Longitudinal valleys are the longitudinal valleys between the lesser Himalayas and Shivalik are known as 'duns' in the west and 'duars' in the east.
- Dun is a local word for valley, particularly an open valley in the Sivaliks or between the Sivaliks and higher Himalayan foothills.
- Other valleys in this region have names like Patli Dun, Kotli Dun, Pinjore Dun in Himachal.

Additional Information
- A longitudinal valley is an elongated valley found between two almost parallel mountain chains in geologically young fold mountains, such as the Alps, Carpathians, Andes, or the highlands of Central Asia.
- They are often occupied and shaped by a subsequent stream.
- Duns are longitudinal valleys created when the Eurasian plate and the Indian plate collided as a result of folding.
- Among lesser Himalayas and Shivalik, they are formed.
- The valleys are accumulated with coarse alluvium passed down by Himalayan rivers.
