NTA UGC NET/JRF Exam, Dec., 2024 Geography

E.L. Ullman identified certain basic factors affecting interactions between regions. These are: There must be demand in a region that can be met by the region. Demand must be able to pay for supply so that two-way movement can develop. Interaction between regions will occur only if production can be moved/transported.
Certain activities require specific facilities. For example, street-trader areas are located near points with maximum inter-city accessibility, port areas are located near suitable waterfronts, and manufacturing areas are located on large landmasses and have access to rail or water transport. Therefore, option (d) is correct.

Regarding energy flow in ecosystems, the "Second Law of Thermodynamics" states that 90% of energy is lost at each trophic level. Energy flows through trophic levels in an ecosystem, and this flow is governed by the following two laws of thermodynamics: Law 1: Energy is neither created nor destroyed in a system with constant mass.
It must undergo transformation. This law is called the law of conservation of energy. Law 2: When energy changes from one form to another or when it is transferred from one place to another, some portion of it dissipates and cannot be recovered. That is, some energy is lost at each point of energy transformation. The flow of energy in an ecosystem is unidirectional.

The correct order of the following states in India in terms of sex ratio as per the 2011 census, from highest to lowest, is as follows:

The correct order of the following theories, arranged in ascending order according to the year of their introduction, is as follows:
(Theory) (Year)
Concentric Zone Theory (by Burgess)                   1925
Central Location Theory (by Christaller)              1933
Sector (Area) Theory (by Hoyt)                               1939
Multinuclear Theory (by Harris and Ullman)      1945
It is therefore clear that if the above theories are arranged in ascending order of their introduction, the answers should be B, A, C, D.
Note: NTA has considered option (c) as the correct answer to this question, which is incorrect. Therefore, the correct option cannot be selected for this question.

The northwestern part of India is inhabited by the Aryan-speaking group known as the Nordic. This is the latest race to arrive in India from Central Asia, also known as the Indo-Aryan. Their bodies are wellbuilt, well-proportioned, tall, with a long and large head, a long face, a long, thin, and high nose, fair complexion, blue eyes, and golden hair. Their representatives are found among the upper castes of Punjab, Haryana, Rajasthan, and western Uttar Pradesh. Herbert Risley (1901) first identified seven races in India based on language and culture, as follows: (1) Turco-Iranian (2) Indo-Aryan (3) Scytho-Dravidian (4) Aryan-Dravidian (5) Mongoloid-Dravidian (6) Mongoloid (7) Dravidian.
