What is the primary composition of the Peninsular Block? A. Sedimentary rocks B. Volcanic rocks C. Ancient gneisses and granites D. Metamorphic rocks Explanation: The Peninsular Block is primarily formed by a great complex of very ancient gneisses and granites. 2 / 202. 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. Faults, folds, and thrust plains C. Karst topography and sinkholes 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. 3 / 203. Which of the following rivers does NOT form a delta before entering the Bay of Bengal? A. Mahanadi B. Narmada C. Kaveri D. Krishna Explanation: The Mahanadi, Krishna, and Kaveri rivers form deltas before entering the Bay of Bengal. The Narmada flows into the Arabian Sea. 4 / 204. What type of mountains mostly make up the Peninsular Block? A. Fault-block mountains B. Relict and residual mountains C. Volcanic mountains D. Fold mountains Explanation: The Peninsular Block mostly consists of relict and residual mountains like the Aravali hills, the Nallamala hills, and others. 5 / 205. Into how many geological divisions can India be divided based on variations in its geological structure and formations? A. Four B. Five C. Three D. Two Explanation: India can be divided into three geological divisions based on variations in its geological structure and formations. 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. The Indo-Ganga-Brahmaputra Plain C. A straight line running from Kachchh to the Ganga delta 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. Which plate was once a part of the Indian plate? A. African plate B. Australian 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. 8 / 208. In contrast to the stable Peninsular Block, how are the Himalayas and other Peninsular mountains characterized in terms of geological structure? A. Highly eroded and weathered B. Dormant volcanic C. Young, weak, and flexible D. Old, rigid, and stable Explanation: Unlike the rigid and stable Peninsular Block, the Himalayas and other Peninsular mountains are young, weak, and flexible in their geological structure. 9 / 209. What is the origin of the mountains in the Himalayas and other Peninsular mountain ranges? A. Erosional B. Depositional C. Volcanic 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. 10 / 2010. 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. Interplay of endogenic and exogenic forces, and lateral plate movements C. Glacial activity and wind erosion D. Chemical weathering and river sedimentation 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. 11 / 2011. What is the approximate age of the Earth? A. 3.8 billion years old B. 5.4 billion years old C. 2.5 billion years old D. 4.6 billion years old Explanation: Current estimations show that the Earth is approximately 4.6 billion years old. 12 / 2012. Which of the following is NOT one of the three geological divisions of India? A. The Deccan Plateau B. The Himalayas and other Peninsular Mountains C. The Indo-Ganga-Brahmaputra Plain D. The Peninsular Block 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. 13 / 2013. In which direction is the Indian plate currently moving? A. Southward B. Northward C. Eastward D. Westward Explanation: The Indian plate is currently moving northward, and this movement has significant consequences on the Indian subcontinent’s physical environment. 14 / 2014. What is the characteristic feature of the river valleys in the Peninsular Block? A. Wide with meandering channels B. Steep-sided with waterfalls C. Deep with high gradients D. Shallow with low gradients Explanation: The river valleys in the Peninsular Block are shallow with low gradients. 15 / 2015. Since which period has the Peninsula been standing like a rigid block? A. Ordovician period B. Cambrian period C. Silurian period D. Precambrian 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. 16 / 2016. Which of the following is NOT an example of a rift valley in the Peninsular Block? A. Tapi B. Godavari C. Narmada D. Mahanadi 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. 17 / 2017. Which forces have played a significant role in shaping the Earth’s surface and subsurface features? A. Gravitational and magnetic forces B. Centrifugal and centripetal forces C. Endogenic and exogenic forces D. Thermal and chemical forces Explanation: Endogenic forces (internal) and exogenic forces (external) have been the primary drivers in shaping the Earth’s surface and subsurface features. 18 / 2018. Where was the Indian plate located millions of years ago? A. South of the equator B. East of the equator C. North of the equator D. West of the equator Explanation: Millions of years ago, the Indian plate was located to the south of the equator. 19 / 2019.
