Geomorphic Processes Questions

Multiple choice

Karst landscapes are the product of

  1. oxidation

  2. carbonic acid action

  3. freeze-thaw weathering

  4. hydrolysis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Karst landscapes are formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum, primarily through the action of carbonic acid in rainwater.

Multiple choice

Which of the following soils is transported by wind?

  1. Colluvial

  2. Eolian

  3. Alluvial

  4. Glacial soil

  5. -

B Correct answer
Explanation

Aeolian or eolian refers to things related to Aeolus, the Greek God of wind. Hence, the soil that is transported by the wind is called as eolian soil.

  1. Seasonal flow

  2. Flow through open and graded shallow valleys with low gradients and little erosion

  3. Meandering tendency and often shifting their beds

  4. A mature state of development

C Correct answer
Explanation

Meandering tendency and often shifting their beds is not a characteristic of peninsular rivers.

Multiple choice

Consider the following statements:

1.         Nilgiri in South India and Narmada valley are examples of rifts formed by faulting. 2.         Peninsular plateau is known as old topography, whereas Himalayas and Northern Plains are considered as new topographies. 3.         Brahmaputra river flows into Assam valley where it is known as Dihang gorge before making its way to Bangladesh.

Which of the statements given above are correct?

  1. 1 and 2

  2. 1 and 3

  3. 2 and 3

  4. 1, 2 and 3
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Statement 1: It is correct. Narmada valley in india lying between Vindhya and Satpura ranges is a rift valley resulted from the formation of block mountains. Similarly, Nilgiri in south are also examples of block mountains and Palghat gap is a low mountain pass which is a rift valley caused by subsidence between two parallel faults, i.e. between Nilgiri hills to the North and Anamalai hills to the South. Statement 2: It is correct. Peninsular Plateau is a tableland, composed of old crystalline, igneous and metamorphic rocks. It is considered as oldest land mass as it was formed due to the drifting of Gondwana land. Statement 3: It is incorrect. Brahmaputra is a transboundry river in Asia that cuts through 3 countries: China, India and Bangladesh. In all these countries, it is known by different names. It originates in Tibet (China), known as Tsangpo River, flows and enters into Arunachal Pradesh (India) where it is called Dihang or siang. Then, it flows further through Assam valley where it is known as Brahmaputra and enters Ramnabazar (Bangladesh) where its known as Jamuna. Hence, the correct option is 1.

  1. clay particles settle on seabed

  2. clay particles settle on fresh water lake bed

  3. sand particles settle on river bed

  4. sand particles settle on seabed
