Indian Rivers, Lakes And Water MCQ Question and Answer | Geography MCQ Question

The correct answer is A: Ganga, Brahmaputra, Hooghly.
Let's break down why:

The Bay of Bengal is a large bay in the northeastern part of the Indian Ocean.
Rivers that flow eastward through India and Bangladesh generally drain into it.

* Option A: Ganga, Brahmaputra, Hooghly - All three of these rivers eventually flow into the Bay of Bengal either directly or through distributaries.

* Option B: Ganga, Yamuna, Godavari - While Ganga and Godavari eventually drain into the Bay of Bengal, the Yamuna is a major tributary of the Ganga, meaning it flows into the Ganga and then finally to the Bay of Bengal.

* Option C: Ganga, Yamuna, Brahmaputra - Again, Yamuna is a tributary of the Ganga, similar to option B.

* Option D: Ganga, Yamuna, Gandak - The Yamuna and Gandak are tributaries of the Ganga.

So, the only group where all rivers mentioned (Ganga, Brahmaputra, and Hooghly) eventually drain into the Bay of Bengal is Option A.

Damodar is a east flowing river with rift valley due to down warping. Down warp denotes a segment of the earth’s crust that is broadly bent downward.

They perform very little erosion activity is not correct about Himalayan River. They perform intensive erosional activity in their upper courses to carry huge loads of silt and sand while it reaches the downstream the Melting glaciers increases the flow of water due to which hugeamount of sediments and deprives plains of the essential nutrients.

Industrial waste and sewage disposal have lead to heavy pollution in River Yamuna that is why it is often termed as open sewage or "khula naala"

The following pairs that are correctly matched are Jog Falls : Sharavati and Sivasamudram Falls : Cauvery.

Ahmedabad is situated on the river bank of Sabarmati. Ahmedabad is located on the banks of the Sabarmati River, 30 km (19 mi) from the state capital Gandhinagar, which is its twin city.

The water of the Luni river is fresh in upper reaches and salty in the lower reaches.

Sivasamudram waterfalls is on the river Cauvery. The Shivanasamudra Falls is on the Kaveri River after the river has found its way through the rocks and ravines of the Deccan Plateau and drops off to form waterfalls.

The Himalayan rivers are snow fed because they receive water from the melting ice of the glaciers as well as from the rains.

The correct answer is Option C: Krishna
Let's understand why:

* River Basin: A river basin is the area of land drained by a river and its tributaries (smaller streams that feed into it).
* Peninsular India: This refers to the part of India that juts out into the Indian Ocean, south of the Indo-Gangetic Plain.
* Highest River Basin: Here, "highest" doesn't mean the river itself is at the highest altitude. It means that among the major peninsular rivers, the Krishna river basin has the largest portion of its area at a higher average elevation than the other rivers mentioned.

Now let's look at the options:

* A: Mahanadi: While a significant river, its basin isn't as elevated overall as the Krishna.
* B: Godavari: The Godavari is a large river, but the Krishna basin has a greater portion at a higher elevation.
* C: Krishna: The Krishna river basin has a considerable part located on the Deccan Plateau, which is at a relatively high elevation. This makes it the highest river basin among the options.
* D: Narmada: The Narmada flows through a relatively lower elevation compared to Krishna's Deccan Plateau region.

Therefore, the Krishna river basin is considered the highest because a large part of its basin lies on the elevated Deccan Plateau.
