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