  • Question 2
    1 / -0
    What type of drainage is formed when the river channel follows the general slope of the terrain?
    Solution
    • In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers and lakes in a particular drainage basin.
    • Dendritic drainage systems are the most common form of drainage system. In a dendritic system, there are many contributing streams (analogous to the twigs of a tree), which are then joined together into the tributaries of the main river (the branches and the trunk of the tree, respectively). 
    • They develop where the river channel follows the slope of the terrain.
  • Question 3
    1 / -0
    _______ drainage pattern develops where hard and soft rocks exists parallel to each other.
    Solution
    A trellis drainage pattern : Occurs where sub parallel streams erode a valley along the strike of less resistant formations. These beds are usually steeply dipping and may be part of a fold system. The tributaries often intersect at right angles where a notch called a water gap cuts through a harder formation.
  • Question 4

  • Question 5
    1 / -0
    The Sutlej in the west, the Ganga in the north and the Brahmaputra in the east are the river streams which constitute the _______.
    Solution
    1. The Satluj Basin:
    The Satluj River along with its main tributary, the Beas, flows towards the south-west. It joins the river Indus in Pakistan. Which finally flows into the Arabian Sea? The Satluj river basins are very fertile. The main crops grown here are wheat, rice, cotton and sugarcane. The Bhakra Dam is built across the Satluj River. Amritsar, Jalandhar, Ludhiana, and Ambala are the important cities of this basin.

    2. The Ganga Basin:
    The Ganga is the most important river in the Northern plains. The river originates as Bhagirathi from a glacier called Gangotri, in the Himalayas. On its way down the hills, Alaknanda and Mandakini rivers join Bhagirathi. The combined waters of these three rivers become the mighty Ganga. It enters the plains as a big river near Rishikesh.

    Many big and small rivers join the Ganga in the plains. The river Yamuna joins Ganga at Allahabad. This place is called Sangam.

    Many Himalayan rivers, such as the Gandak, Gomti, Ghaghra and Kosi, join Ganga on its journey eastwards. The Chambal, Sind, Betwa and Son rivers join the Ganga from its southern side.

    The Ganga flows through the states of Uttaranchal, Uttar Pradesh, Bihar and west Bengal, it splits into two branches.

    One branch is the Hugli, which, flows through the city of Kolkata. The other branch enters Bangladesh and is known as the Padma. There are many holy cities in the Ganga basin. Find their names.

    3. The Brahmaputra basin:
    The Brahmaputra River rises in Tibet and enters India from the east. It flows through a narrow valley in Assam. Here, the river is always flooded in the rainy season. It enters Bangladesh and joins River Padma. The Ganga and Brahmaputra rivers together from the largest delta in the world before flowing into the Bay of Bengal. This area is known as Sunder bans.

    The rivers coming from the Himalayas have plenty of water throughout the year. The snow and ice melt during the summer and the water flows into the rivers.

    The Northern Plains are heavily populated as the area is very fertile and produces a large quantity of food grain. It can hence support a large population.

    A large number of cities have developed in the Northern Plains. A number of big and small factories have come up along the banks of the rivers. Their waste products flowing into the river have made the water polluted. All of us must help the government in keeping these rivers free from pollution. Human as well as animal life will be in danger if these rivers do not remain clean.

  • Question 8
    1 / -0
    The area drained by a single river system is called _________.
    Solution
    A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. The drainage basin includes all the surface water from rain runoff, snowmelt, and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface. Drainage basins connect into other drainage basins at lower elevations in a hierarchical pattern, with smaller sub-drainage basins, which in turn drain into another common outlet.

    Other terms used interchangeably with drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, the term watershed is commonly used to mean a drainage basin, though in other English-speaking countries, it is used only in its original sense, that of a drainage divide.

    In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground.
  • Question 9
    1 / -0
    Which one of the following rivers thrice forks into two streams and reunites a few miles farther on, thus forming the islands of Shivanasamudra and Srirangam?
    Solution
    Cauvery rivers thrice forks into two streams and reunites a few miles farther on, thus forming the islands of Srirangapatanam, Sivasamudram and Srirangam.

The river flows in the westward direction, and empties into the Arabian Sea in Bharuch district of Gujarat.
