Key Points

• Principle of Increasing Complexity:
  • ​It lays down that the entities may be arranged in the order of their increasing complexity, e.g., Linguistic elements can be arranged as syllables, words, phrases, clauses, sentences, paragraphs, chapters, books, and so on.
  • Algebraic equations can be arranged as 1st order, 2nd order, 3rd order equations, etc.
  • Quantity and complexity are concomitant to one another. If the national library is large it is also hugely complex compared to a village library.
  • Simillarly the above subjects can be arranged as:
    • Mathematical geography (D) - deals with the basic principles and calculations in geography, making it relatively less complex compared to others.
    • Biogeography (A) - focuses on the distribution of species and ecosystems, adding more complexity than mathematical geography.
    • Anthropogeography (B) - focuses on the relationship between humans and the environment, which is a more complex interaction than biogeography.
    • Political geography (C) - involves the political structures and their geographical implications, which is more complex due to the influence of political systems.
    • Economic geography (E) - the most complex as it incorporates economic systems, political factors, and environmental influences, making it a highly interdisciplinary and complex subject.
