-
What formed the basis of teleological geomorphic theories?
Options:

- Biologists and naturalists
-
What are the dominant theories during the 18th and 19th centuries in geomorphology?
Options:
- Teleological theories
- Immanent theories
- Uniformitarian theories
- Causal theories
-
What is the relationship between geology and landforms according to J.P. Lesley, W. Smith and J.W. Powell?
Options:
- There is no relationship between geology and landforms
- There is a random relationship between geology and landforms
- There is a clearcut expression of structure in landforms
- There is a uniform relationship between geology and landforms
-
What is the main goal of geomorphic theories?
Options:
- Prediction of future events and changes in landforms and processes.
- Description of landforms in evolutionary manner.
- Explanation of the formation of unique events.
- None of the above.
-
Which theories are considered as historical theories?
Options:
- Models of cycle of erosion.
- Denudation chronology.
- Tectonic theory.
- All of the above.
-
Why are historical theories not considered scientific theories?
Options:
- Because they are based on unique events and non-repeatable processes.
- Because they are based on a host of events and their recurrence.
- Because they are based on a combination of scientific and historical events.
- None of the above.
-
Which theoretical model is considered as the first successful attempt for the formulation of theoretical model in geomorphology?
Options:
- Cycle of erosion.
- Denudation chronology.
- Geographical cycle.
- Tectonic theory.
-
What is the aim of the denudation chronology model?
Options:
- Prediction of future events and changes in landforms and processes.
- Description of landforms in evolutionary manner.
- Reconstruction of successive stages of the earth's history.
- None of the above.
-
What is the main criticism against Davisian model of geographical cycle?
Options:
- It begins on the basis of initial conclusion drawn from the study of maps of the region concerned.
- It involves very long temporal and very large spatial scales.
- It is not based on any logical arguments.
- None of the above.
-
Why could not the tectonic theory of W. Penck gain as much popularity as denudation chronology?
Options:
- Because of language, political and personal considerations on the one hand, and less technical assumptions on the other.
- Because it involves very long temporal and very large spatial scales.
- Because it is not based on any logical arguments.
- None of the above.
-
Why did historical theories start losing their ground and popularity after 1950?
Options:
- Because they involved very short temporal and very small spatial scales.
- Because they involved very long temporal and very large spatial scales.
- Because they were not based on any logical arguments.
- None of the above.
-
What was the main reason for the breakdown of historical theories?
Options:
- Because their time scales were so large and unsignposted that they became the playground for unbridled and untestable speculation.
- Because they were not based on any logical arguments.
- Because they involved very short temporal and very small spatial scales.
- None of the above.
-
What was the reason behind the growth of regional taxonomic studies in geomorphology?
Options:
- The availability of huge datasets regarding landforms after 1890.
- The popularity of dualism in human geography.
- The invention of new technologies in geomorphology.
- The discovery of new landforms.
-
What is dualism in geomorphology?
Options:
- The division of the globe into morphogenetic regions.
- The growth of regional taxonomic studies.
- The classification of landform assemblages.
- The theoretical binality of taxonomy.
-
Which two major geomorphic concepts provided the base for taxonomic theories in geomorphology?
Options:
- Climatic geomorphology and morphological geomorphology.
- Regional taxonomy and land classification.
- Humidity and temperature.
- Morphogenetic regions and landform assemblages.
-
What is the main basis of functional theories in geomorphology?
Options:
- The relationship between landforms and processes
- The relationship between landforms and climate
- The relationship between erosion and sedimentation
- The relationship between tectonic activity and landforms
-
What was the major methodological shift in geomorphology after World War II?
Options:
- The emergence of functional theory
- The development of mathematical methods
- The study of large-scale drainage networks
- The application of statistical and mathematical methods to the study of landforms and processes
-
Who used functional basis for the interpretation of landforms and processes even before the formal emergence of quantitative geomorphology?
Options:
- R.E. Horton
- G.K. Gilbert
- Classic functional science
- Palimpsest topography
-
What was the primary goal of the emergence of functional theory in geomorphology?
Options:
- To relate morphological forms to their controlling factors
- To study large-scale drainage networks
- To develop a genetic model for the development of landforms
- To study the relationship between climate and landforms
-
What is the formidable problem faced by the functional theory in relating present-day landforms to present processes?
Options:
- The absence of statistical and mathematical methods
- The absence of data on rapid temporal changes
- The absence of data on relict landforms
- The absence of data on large-scale drainage networks
