Fold mountains Explanation: The Peninsular Block mostly consists of relict and residual mountains like the Aravali hills, the Nallamala hills, and others. 2 / 202. Which of the following is NOT one of the three geological divisions of India? A. The Indo-Ganga-Brahmaputra Plain B. The Himalayas and other Peninsular Mountains C. The Peninsular Block D. The Deccan Plateau Explanation: The three geological divisions of India are the Peninsular Block, the Himalayas and other Peninsular Mountains, and the Indo-Ganga-Brahmaputra Plain. The Deccan Plateau is a physiographic division, not a geological one. 3 / 203. Which fault separates the northeastern parts of the Peninsular Block from the Chotanagpur plateau? A. Malda fault B. Main Boundary Fault C. Bhima fault D. Karakoram Fault Explanation: The northeastern parts of the Peninsular Block are separated from the Chotanagpur plateau by the Malda fault in West Bengal. 4 / 204. What is the approximate age of the Earth? A. 2.5 billion years old B. 3.8 billion years old C. 4.6 billion years old D. 5.4 billion years old Explanation: Current estimations show that the Earth is approximately 4.6 billion years old. 5 / 205. What is the primary composition of the Peninsular Block? A. Sedimentary rocks B. Ancient gneisses and granites C. Volcanic rocks D. Metamorphic rocks Explanation: The Peninsular Block is primarily formed by a great complex of very ancient gneisses and granites. 6 / 206. What is the northern boundary of the Peninsular Block? A. An irregular line running from Kachchh along the western flank of the Aravali Range near Delhi and then roughly parallel to the Yamuna and the Ganga as far as the Rajmahal Hills and the Ganga delta B. A straight line running from Kachchh to the Ganga delta C. The Indo-Ganga-Brahmaputra Plain D. The Himalayas Explanation: The northern boundary of the Peninsular Block is an irregular line running from Kachchh along the western flank of the Aravali Range near Delhi and then roughly parallel to the Yamuna and the Ganga as far as the Rajmahal Hills and the Ganga delta. 7 / 207. What is the primary cause for the formation of the present geological structure and geomorphologic processes in the Indian subcontinent? A. Glacial activity and wind erosion B. Chemical weathering and river sedimentation C. Solar radiation and volcanic activity D. Interplay of endogenic and exogenic forces, and lateral plate movements Explanation: The present geological structure and geomorphologic processes in the Indian subcontinent are primarily the result of the interplay of endogenic and exogenic forces, and lateral plate movements. 8 / 208. Since which period has the Peninsula been standing like a rigid block? A. Precambrian period B. Silurian period C. Ordovician period D. Cambrian period Explanation: Since the Cambrian period, the Peninsula has been standing like a rigid block, with the exception of some of its western coast and other parts affected by tectonic activity. 9 / 209. Into how many geological divisions can India be divided based on variations in its geological structure and formations? A. Three B. Four C. Five D. Two Explanation: India can be divided into three geological divisions based on variations in its geological structure and formations. 10 / 2010. Which of the following rivers does NOT form a delta before entering the Bay of Bengal? A. Kaveri B. Narmada C. Krishna D. Mahanadi Explanation: The Mahanadi, Krishna, and Kaveri rivers form deltas before entering the Bay of Bengal. The Narmada flows into the Arabian Sea. 11 / 2011. Which of the following landforms is NOT indicative of the youthful stage of river development in the Himalayas and other Peninsular mountains? A. Gorges B. V-shaped valleys C. Rapids D. Meanders Explanation: Gorges, V-shaped valleys, and rapids are landforms indicative of the youthful stage of river development in the Himalayas and other Peninsular mountains. Meanders are characteristic of mature or old-age rivers. 12 / 2012. In which direction is the Indian plate currently moving? A. Southward B. Westward C. Northward D. Eastward Explanation: The Indian plate is currently moving northward, and this movement has significant consequences on the Indian subcontinent’s physical environment. 13 / 2013. Where was the Indian plate located millions of years ago? A. South of the equator B. West of the equator C. East of the equator D. North of the equator Explanation: Millions of years ago, the Indian plate was located to the south of the equator. 14 / 2014. Which of the following is NOT an example of a rift valley in the Peninsular Block? A. Narmada B. Mahanadi C. Tapi D. Godavari Explanation: The rift valleys of the Narmada, the Tapi, and the Mahanadi are examples of rift valleys in the Peninsular Block. The Godavari is not a rift valley. 15 / 2015. In contrast to the stable Peninsular Block, how are the Himalayas and other Peninsular mountains characterized in terms of geological structure? A. Old, rigid, and stable B. Highly eroded and weathered C. Dormant volcanic D. Young, weak, and flexible Explanation: Unlike the rigid and stable Peninsular Block, the Himalayas and other Peninsular mountains are young, weak, and flexible in their geological structure. 16 / 2016. What is the origin of the mountains in the Himalayas and other Peninsular mountain ranges? A. Volcanic B. Depositional C. Erosional D. Tectonic Explanation: The mountains in the Himalayas and other Peninsular mountain ranges are tectonic in origin, formed by the movement and collision of Earth’s plates. 17 / 2017. Which plate was once a part of the Indian plate? A. Antarctic plate B. African plate C. Eurasian plate D. Australian plate Explanation: The Australian plate was once a part of the Indian plate before they separated millions of years ago. 18 / 2018. What type of landforms are commonly found in the Himalayas and other Peninsular mountains due to their geological structure? A. Plateaus and mesas B. Sand dunes and playas C. Faults, folds, and thrust plains D. Karst topography and sinkholes Explanation: The young, weak, and flexible geological structure of the Himalayas and other Peninsular mountains makes them prone to the development of faults, folds, and thrust plains. 19 / 2019. What is the characteristic feature of the river valleys in the Peninsular Block? A. Shallow with low gradients B. Wide with meandering channels C. Deep with high gradients D. Steep-sided with waterfalls Explanation: The river valleys in the Peninsular Block are shallow with low gradients. 20 / 2020. Which forces have played a significant role in shaping the Earth’s surface and subsurface features? A. Endogenic and exogenic forces B. Centrifugal and centripetal forces C. Thermal and chemical forces D. Gravitational and magnetic forces Explanation: Endogenic forces (internal) and exogenic forces (external) have been the primary drivers in shaping the Earth’s surface and subsurface features.
