unacademy Q91.Consider the following statements: 1.The Pitti Islet is an important nesting sites for many birds. 2.The only confirmed active volcano of India is found on the Barren Island. Select the correct answer using the code given below? A)1 only B)2 only C)Both 1 and 2 D)Neither 1 nor 2
unacademy Answer-c) Both 1 and 2 Pitti (Pitli) or "Pakshpitti" ( meaning bird) is an uninhabited coral islet in UT of Lakshadweep, India. It is an important nesting place for pelagic birds. Barren Island is located in the Andaman sea. It is dominated by Barren volcano which is the only active volcano along a chain of volcanoes from Sumatra to Myanmar As its name, it has a barren landscape uninhabited by humans and is devoid of any significant vegetation.
unacademy Q92.Which of the following is correctly matched in the regards of physical features of India? |Himalayan Mountains 2.Northern Plains 3.Peninsular Plateau Sources of fresh Water and Forest Granaries of the country Storehouse of Minerals Source of Solar energy Site of Fishing and Ports 4.Desert region 5.Coastal region and Islands Select the correct answer using the code given below? A) 1 and 2 only B) 2, 4 and 5 only C) 1,3 and 5 only D) All of the above
unacademy Answer-D) All of the above The physical features of India can be grouped under the following physiographic divisions: 1.The Himalayan Mountains 2.The Northern Plain 3.The Peninsular Plateau 4.The Indian Desert 5.The Coastal Plains 6. Islands These physiographic units highlights the unique features of each region and each region complements the other diverse physical featur
unacademy Q93. Consider the following statements: 1.Drainage systems are the patterns formed by the streams, rivers and their tributaries in a particular drainage basin. 2.The area drained by a single river system is called a drainage basin. Select the correct answer using the code given below? A) 1 only B) 2 only C) Both 1 and 2 D) Neither 1 nor 2
unacademy Answer-C) Both 1 and 2 The drainage system is also known as the river system of an area. Small streams flowing from different directions come together to form the main river, which ultimately drains into a large water body such as a lake or a sea or an ocean. The world's largest drainage basin is of the Amazon river in South America. In India, the river Ganga has a large drainage system in the northern plain.
unacademy Q94.Which of the following are the patterns of the drainage pattern formed by the streams? 1.Dendritic 2.Trellis 3.Rectangular 4.Radial Select the correct answer using code below? A) 1 and 2 Only B) 2, 3 and 4 Only C) 3 and 4 only D) All of the above
unacademy Answer-D) All of the above The streams within a drainage basin form certain patterns, depending on the slope, underlying rock structure as well as the climatic conditions of the area. These are following: 1.Dendritic 2.Trellis 3.Rectangular 4.Radial 5 Centripetal 6.Annular
unacademy 095.Consider the following statements: 1.Dendritic pattern develops where the river channels follows the slope of the terrain. 2.A rectangular drainage pattern develops on a strongly jointed rocky terrain. Select the correct answer using the code given below? A) 1 only B) 2 only C) Both 1 and 2 D) None of the above
unacademy Answer-C) Both 1 and 2 The stream with its tributaries resembles the branches of a tree, thus called Dendritic. It forms in V-shaped valleys Rectangular drainage develops on rocks that are of approximately uniform resistance to erosion, but which have two directions of joining at approximately right angles. The joints are usually less resistant to erosion than the bulk rock so erosion tends to preferentially open the joints and streams eventually develop along the joints.
unacademy Q97. Consider the following statements: 1.Most of the Himalayan rivers are perennial because they are fed with melting glaciers in summer. 2.Himalayn rivers have short courses from their source to the sea. Select the correct answer using the code given below? A) 1 only B) 2 only C) Both 1 and 2 D) Neither 1 nor 2
unacademy 098. Consider the following statements: 1.The Himalayan rivers performs intensive erosional activity in their lower course. 2.In their upper course, these rivers forms many depositional features. Select the correct answer using the code given below? A) 1 only B) 2 only C) Both 1 and 2 D) Neither 1 nor 2
unacademy Answer-D) Neither 1 nor 2 The Himalayan rivers performs intensive erosional activity in their upper course and carry hug loads of silt and sand. In the middle and lower courses, these rivers forms meanders, oxbow lakes, and many depositional features in their floodplains. They also have well developed deltas in senile stage.
unacademy 099. Consider the following statements: 1.Most of the peninsular rivers have matured and are seasonal. 2.They have short and shallow courses. 3.Most of them originate in the eastern ghats and flow towards the Bay of Bengal. Select the correct answer using the code given below? A) 1 and 2 only B) 2 and 3 only C) 1 and 3 only D) All of the above
unacademy Answer-A) 1 and 2 only A large number of peninsular rivers are seasonal, as their flow is dependent on rainfall. During the dry season, even the large rivers have reduced flow of water in their channels. Most of them originate in the western ghats and flow towards the Bay of Bengal due to general inclination plateau towards east. However, some of them originate in the central highlands and flow towards the west.
unacademy Q100. Which of the following are the peninsular rivers which flow towards the west? 1.Godavari 2.Narmada 3.Tapti 4.Penganga 5.Mahi Select the correct answer using the code given below? A) 1, 2, 3 only B) 2, 3 and 4 only C) 2, 3, and 5 only D) 2, 3, 4 and 5 only
unacademy Answer-C) 2, 3 and 5 only The general gradient of peninsular India is west to east. The rivers Godavari and Penganga, and all the rivers flow eastward and drain in the Bay of Bengal. Narmada and Tapti rivers flow through the rift valleys which have a different gradient. So they flow westward. Mahi River- Mahi is one of the major interstate west flowing rivers of India, the Mahi basin extends over states of Madhya Pradesh, Rajasthan and Gujarat.
