Correct Answer

Options:

1. A drainage system that develops on a different geological formation than the one it flows on
2. A drainage system that flows across the Himalayas
3. A drainage system that flows parallel to the geological structure of the region
4. A drainage system that flows on a flat ground surface

Correct Answer

Options:

1. By lateral erosion
2. By vertical erosion
3. By meandering
4. By deposition

Correct Answer

Options:

1. The anticline degrades the river through upwarping.
2. The anticline degrades the river through downcutting.
3. The anticline controls the development of the river valley.
4. The anticline has no effect on the development of the river valley.

Correct Answer

Options:

1. Superimposed drainage systems represent the maintenance of the former course of the river, while antecedent drainage systems represent the superimposition of the valley on the lower structure.
2. Superimposed drainage systems represent the superimposition of the valley on the lower structure, while antecedent drainage systems represent the maintenance of the former course of the river.
3. Superimposed drainage systems can develop regardless of any upliftment of the land area, while antecedent drainage systems require upliftment of the land are
4. Superimposed drainage systems are more complex than antecedent drainage systems.

Correct Answer

Options:

1. Because new drainage systems were evolved on the new surface formed due to cooling and solidification of lavas erupted during the Cretaceous and early Tertiary periods.
2. Because the region experienced significant upliftment of the land are
3. Because the region is composed of highly resistant rocks that are difficult to erode.
4. Because the region is located in a high precipitation zone that promotes the development of superimposed drainage systems.

Correct Answer

Options:

1. Because the Khainjua ridges are composed of lower Vindhyanas which were folded and warped before the deposition of the upper Vindhyan sedim entries’.
2. Because there are no evidences to support any localized rise in the ridges after Cambrian perio
3. Because the evidence of laterites to the north of Kaimur scarps denotes the spread of basaltic lava of the Deccan trapean age of Cretaceous period which might have buried and obliterated previous draiange lines.
4. All of the above.
