    3. Tectonic theory.
    4. All of the above.

    Option: D

  6. Why are historical theories not considered scientific theories?

    Options:
    1. Because they are based on unique events and non-repeatable processes.
    2. Because they are based on a host of events and their recurrence.
    3. Because they are based on a combination of scientific and historical events.
    4. None of the above.

    Option: A

  7. Which theoretical model is considered as the first successful attempt for the formulation of theoretical model in geomorphology?

    2. Denudation chronology.
    3. Geographical cycle.
    4. Tectonic theory.

    Options:
    1. Prediction of future events and changes in landforms and processes.

    3. Reconstruction of successive stages of the earth's history.
    4. None of the above.

    Option: C

  9. What is the main criticism against Davisian model of geographical cycle?

    Options:
    1. It begins on the basis of initial conclusion drawn from the study of maps of the region concerned.
    2. It involves very long temporal and very large spatial scales.
    3. It is not based on any logical arguments.
    4. None of the above.

    Option: A

  10. Why could not the tectonic theory of W. Penck gain as much popularity as denudation chronology?

    Options:
    1. Because of language, political and personal considerations on the one hand, and less technical assumptions on the other.
    2. Because it involves very long temporal and very large spatial scales.
    3. Because it is not based on any logical arguments.
    4. None of the above.

    Option: A

  11. Why did historical theories start losing their ground and popularity after 1950?

    Options:
    1. Because they involved very short temporal and very small spatial scales.
    2. Because they involved very long temporal and very large spatial scales.
    3. Because they were not based on any logical arguments.
    4. None of the above.

    Option: B

  12. What was the main reason for the breakdown of historical theories?

    Options:
    1. Because their time scales were so large and unsignposted that they became the playground for unbridled and untestable speculation.
    2. Because they were not based on any logical arguments.
    3. Because they involved very short temporal and very small spatial scales.
    4. None of the above.

    Option: A

  13. What was the reason behind the growth of regional taxonomic studies in geomorphology?

    Options:
    1. The availability of huge datasets regarding landforms after 1890.

    3. The invention of new technologies in geomorphology.
    4. The discovery of new landforms.

    Option: A

  14. What is dualism in geomorphology?

    Options:
    1. The division of the globe into morphogenetic regions.
    2. The growth of regional taxonomic studies.
    3. The classification of landform assemblages.
    4. The theoretical binality of taxonomy.

    Option: D

  15. Which two major geomorphic concepts provided the base for taxonomic theories in geomorphology?

    Options:
    1. Climatic geomorphology and morphological geomorphology.
    2. Regional taxonomy and land classification.
    3. Humidity and temperature.
    4. Morphogenetic regions and landform assemblages.

    Option: A
