Indian Rivers and Waterways

Wular Lake in Jammu and Kashmir is India's largest freshwater lake. It spans approximately 100-200 square kilometers depending on seasonal variations. Chilka Lake is actually a brackish water lagoon, while Powai and Dal Lake are much smaller freshwater bodies.

Rivers have three distinct stages in their course: the upper course (torrent stage) where erosion is dominant, the middle course (valley stage) where transport occurs, and the lower course (plain stage) where deposition is primary. Therefore, all three options A, B, and C represent valid stages of a river.

Mettur Dam is built across the Kaveri (also spelled Cauvery) River in Tamil Nadu, India. It is one of the largest dams in India and serves irrigation and power generation needs. The Mahanadi (B), Krishna (C), and Godavari (D) are major rivers in India but not the river on which Mettur Dam is situated.

The Damodar River was historically called 'Bengal's Sorrow' due to its devastating floods in the Bengal region (now Jharkhand and West Bengal). The frequent flooding caused massive damage to life and property before the Damodar Valley Corporation project was initiated to control it.

Sutlej River originates from Tibet (specifically near Mount Kailash in the Tibetan plateau). It flows through Himachal Pradesh and Punjab before entering Pakistan.

The Ganges-Brahmaputra Delta is the world's largest river delta, formed by the confluence of the Ganga (Ganges) and Brahmaputra rivers in Bangladesh and India. This massive delta spans approximately 105,000 square kilometers and is formed by sediment deposition where these rivers empty into the Bay of Bengal. The Mahanadi and Narmada form smaller deltas, while the Yamuna is a tributary of the Ganga.

The Sutlej River originates from Lake Rakshastal near Mount Kailash in Tibet (China). It's one of the longest rivers of the Trans-Himalayan region. The river then flows into India through Himachal Pradesh and Punjab before joining the Indus river system.

The Nile River is widely recognized as the world's longest river, stretching approximately 6,650 km through northeastern Africa. While the Amazon River has competing length claims depending on measurement methodology, the Nile remains the standard answer in most geographical contexts.

The Congo River is recognized as the world's deepest river, with depths reaching over 220 meters (720 feet) in certain sections. Other major rivers like the Yangtze and Mississippi have significantly lower maximum depths, making Congo the correct answer.

The Ganges is India's longest river at approximately 2,525 km from its source in Gangotri to the Bay of Bengal. Brahmaputra is longer in total length but much of its course is outside India (in Tibet and Bangladesh). Godavari is India's longest peninsular river but shorter overall.

The Hooghly River, a distributary of the Ganga, flows through Kolkata. The city grew around this vital waterway which served as a major port and trade route during colonial times. The other options (Padma, Yamuna, Damodar) flow through other regions of India.

The Hooghly River, a distributary of the Ganga, flows by Kolkata. The city developed on the east bank of the Hooghly, and this river has been crucial to Kolkata's history and trade. The Padma flows through Bangladesh, while the Yamuna flows through North India.

The Sutlej River originates from Lake Rakshastal near Mount Kailash in the Tibet Autonomous Region of China. It is the longest of the five rivers that flow through the historic crossroad region of Punjab. The river enters India through Shipki La pass in Himachal Pradesh.
