  • Question 1
    1 / -0
    Which of the following options correctly defines `drainage basin`?
    Solution
    The area drained by a single river system is called a drainage basin.
  • Question 2
    1 / -0
    Which of the following rivers has the largest river basin in India?
    Solution
    Ganga river has the largest basin in India.
  • Question 3
    1 / -0
    In which of the following courses of river does meander lie?
    Solution
    The middle course of a river has more energy and volume than in the upper course. The gradient is more gentle and lateral (sideways) erosion widens the channel. The river channel also becomes deeper. Meanders are typical landforms found in this stage of the river.
  • Question 4
    1 / -0
    Which of the following is not the depositional feature of Himalayan Rivers in flood plains?
    Solution
    Himalayan Rivers form meanders, oxbow lakes, delta and many other depositional features in their food plains, but `waterfall` is not a depositional feature. It is, rather, an erosional feature at upper course of river.
  • Question 5
    1 / -0
    Which of the following drainage patterns develops when streams flow in different direction from a central peak or dome-like structure?
    Solution
    A drainage pattern in which consequent streams radiate or diverge outward, like the spokes of a wheel, from a high central area; it is best developed on the slopes of a young, unbreached domal structure or of a volcanic cone.
  • Question 6
    1 / -0
    Which of the following is/are not the feature(s) of the Himalayan rivers?

    (I) These rivers have shorter and shallower courses as compared to the Peninsular rivers.
    (II) These are seasonal rivers.
    (III) These rivers perform intensive erosional activity in their upper courses.
    Solution
    The Indian rivers are divided into two major groups: the Himalayan rivers and the Peninsular rivers.
    The major Himalayan rivers are the Indus, Ganges, and Brahmaputra. These rivers are long, and are joined by many large and important tributaries. The Himalayan rivers have long courses from their source to sea (in India Arabian Sea and Bay of Bengal). These rivers are perennial; that is, they have water throughout the year. These rivers receive water from rain as well as from melted snow from the lofty mountains. The Himalayan rivers perform intensive erosional activity in their upper courses and carry huge loads of silt and sand, whereas peninsular rivers do not.
  • Question 7
    1 / -0
    Which of the following is not a tributary of river Indus?
  • Question 8
    1 / -0
    Which of the following rivers is called the `Headwaters of Ganga`?
    Solution
    Bhagirathi is the source stream of Ganga. It emanates from Gangotri Glacier at Gaumukh at an elevation of 3,892 m (12,770 feet). Many small streams comprise the headwaters of Ganga. The important among these are Alaknanda, Dhauliganga, Pindar, Mandakini and Bhilangana.
  • Question 9
    1 / -0
    Sunderban delta is formed by which of the following rivers?
    Solution
    Sundarbans delta is formed by the Ganga and Brahmaputra rivers. The Ganges-Brahmaputra Delta (also known as the Brahmaputra Delta, the Sundarbans Delta or the Bengal Delta) is a river delta in the Bengal region of the Indian subcontinent. The name Sundarbans is thought to be derived from sundri or Sundari (Heritiera fomes), the name of the large mangrove trees that are most plentiful in the area.
  • Question 10
    1 / -0
    Which of the following correctly shows the location of Kosi river in the map of India?

  • Question 11
    1 / -0
    Which of the following rivers flows between Ghaghara River and Yamuna River?
    Solution
    Ganga River flows between Ghaghara River and Yamuna River. The total length of Ghaghara River up to its confluence with the Ganga at Revelganj in Bihar is 1,080 kilometres (670 mi). It is the largest tributary of the Ganga by volume and the second longest tributary of the Ganga by length after Yamuna. Arising from the source, river Yamuna flows through a series of valleys for about 200 kilometres in lower Himalayas and emerges into Indo-Gangetic plains. In the upper reaches, the main valley is overlooked by numerous hanging valleys, carved by glaciers during the last ice ages. The gradient of the river is steep here and the entire geomorphology of the valley is influenced by the passage of the river. In the upper stretch of 200 km, it draws water from several major streams.
  • Question 12
    1 / -0
    Which of the following Himalayan Rivers is marked by huge deposits of sill on its bed causing the river bed to rise?
    Solution
    The Brahmaputra rises in Tibet; east of Mansarowar lake. It is a little longer than the Indus. Most of the course of the Brahmaputra lies outside India. It flows eastwards parallel to the Himalayas. Unlike other north Indian rivers the Brahmaputra gets huge deposits of silt on its bed. This results in rising of the river bed. It also shifts its channel frequently.
  • Question 13
    1 / -0
    Which of the following is not a Peninsular River?
    Solution
    The peninsular Rivers in India include the Mahanadi, Godavari, Krishna, Cauvery, Narmada, and Tapti or Tapi. The Gandaki River, also known as the Narayani and the Gandak, is one of the major rivers in Nepal and a left bank tributary of the Ganges in India. Its total catchment area amounts to 46,300 km², most of it in Nepal. In the Nepal Himalayas, it is notable for its deep canyon.
  • Question 14
    1 / -0
    Which of the following is the largest Peninsular River?
  • Question 15
    1 / -0
    Which of the following is not a tributary of the Krishna River?
  • Question 16
    1 / -0
    River Kaveri reaches Bay of Bengal through which of the following states?
    Solution
    Originating in the foothills of Western Ghats at Talakaveri, Kodagu in Karnataka it flows generally south and east through Karnataka and Tamil Nadu and across the southern Deccan plateau through the southeastern lowlands, emptying into the Bay of Bengal through two principal mouths in Poompuhar, Tamil Nadu.
  • Question 17
    1 / -0
    The Krishna drainage basin is shared by which of the following states of India?
    Solution
    The Krishna River is the fourth-biggest river in terms of water inflows and river basin area in India, after the Ganga, Godavari and Brahmaputra. The river is almost 1,288 kilometres (800 mi) long. The river is also called Krishnaveni. It is one of the major sources of irrigation for Maharashtra, Karnataka, Telangana and Andhra Pradesh. The Krishna river originates in the Western Ghats near Mahabaleshwar at an elevation of about 1,300 metres (4,300 ft), in the state of Maharashtra in central India.
  • Question 18
    1 / -0
    Which of the following is the largest freshwater lake in India?
    Solution
    Wular Lake (also spelt Wullar) is one of the largest fresh water lakes in Asia. It is sited in Bandipora district in Jammu and Kashmir, India. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River.
  • Question 19
    1 / -0
    Which of the following is a salt water lake?
  • Question 20
    1 / -0
    Which of the following is not a natural lake?
    Solution
    Most lakes have at least one natural outflow in the form of a river or stream, which maintain a lake's average level by allowing the drainage of excess water. Some lakes do not have a natural outflow and lose water solely by evaporation or underground seepage or both. They are termed endorheic lakes. Gobind Sagar Lake is a Reservoir situated in Una and Bilaspur districts of Himachal Pradesh. It is formed by the Bhakra Dam. The Reservoirs is on the River Sutlej and is named in honour of Guru Gobind Singh, the tenth Sikh guru.
  • Question 21

    In which of the following states is Kolleru Lake situated?
    Solution
    Kolleru Lake, also called Colair Lake, is located in northeastern Andhra Pradesh state, southern India. It lies between the Godavari and Krishna river deltas near the city of Eluru. During the height of the summer monsoon rainy season, the lake may expand to 100 square miles (260 square km). Carp and prawns are fished commercially in the lake, and prawns are processed at the village of Akid.
  • Question 22
    1 / -0
    What is the full form of NRCP?
  • Question 23
    1 / -0
    Which of the following are true about the Ganga Action Plan?

    (I) Ganga Action Plan has been merged with the NRCP.
    (II) Under this action plan, no scheme has been completed till now.
    (III) Under this action plan, pollution abatement works have been taken up in 57 towns.
    Solution
    The Central Government started the river pollution abatement programme with the launching of the Ganga Action Plan (GAP-I) in the year 1985. Subsequently, the GAP Phase II was launched in 1993 for pollution abatement of river Yamuna and Gomti, major tributaries of river Ganga. The river pollution abatement programme was further expanded to include other major rivers of the country in 1995 under the aegis of National River Conservation Plan (NRCP). Finally in December 1996, GAP Phase II was also merged with the NRCP and all projects for river cleaning in the country were brought under one umbrella scheme of NRCP. The objective of NRCP is to reduce the pollution load in rivers through implementation of various pollution abatement works, thereby improving their water quality.

    The expanded NRCP now covers 152 towns located along 27 interstate rivers in 16 states. Under this action plan, pollution abatement works were taken up in 57 towns. A total of 215 schemes of pollution abatement were sanctioned. So far, 69 schemes have been completed under this action plan. A million litres of sewage is targeted to be intercepted, diverted and treated.
