Which of the following rivers occupies a riftvalley?

  1. Narmada

  2. Cauvery

  3. Mahanadi

  4. Sutlej


Correct Option: A
Explanation:

Narmada river rises in the Amarkantaka hills in Madhya Pradesh. It flows towards the west in a rift valley formed due to faulting. Its length is about 1312 km. This river drains into the Arabian Sea. It flows through the states of Madhya Pradesh, Maharashtra, and Gujarat.

Which of the following regions is the best example of Rift Valley?

  1. Peninsular India

  2. East Africa

  3. Dead-Sea basin

  4. Scotland


Correct Option: B
Explanation:
  • A Rift valley is a narrow linear depression in the land surrounded by mountain ranges. It is created by a geological fault in earth's crust. The East African Rift valley which runs thousands of km long is the best example of a Rift valley in the world.

Rift valley means _______________________.

  1. A steep valley by river erosion

  2. A valley with gentle slopes

  3. A valley formed by the sinking of ground between two almost parallel faults

  4. A valley carved by aeolian erosion


Correct Option: C
Explanation:
  • When two plates of earth's crust move apart from each other, a long narrow depression is formed due to the sinking of ground which is called a rift valley eg. east African rift valley. Hence option C is the right answer.
  • The rift valley is not formed due to river or aeolian(wind) action. Also, the slope in the rift valley is almost vertical thus very steep hence other options are incorrect.

The seas which are extensions of ocean and are partially surrounded by land are called ___________.

  1. bay

  2. marginal sea

  3. inland sea

  4. lagoons


Correct Option: B
Explanation:

Marginal seas are similar to open oceans with respect to being created by large scale geological processes, exhibiting biodiversity, and possessing layered water circulation patterns. The main difference between the two is related to depth and proximity to landmasses. The seas which are extensions of the ocean and are partially surrounded by land are known as marginal sea.
