Explanations:The Deccan Plateau is a significant geographical feature in India, covering a large part of the southern and central regions. It is characterized by its volcanic rock formations, which have played a crucial role in the architectural and cultural heritage of the region. The volcanic rocks, primarily basalt, are not only abundant but also durable and suitable for construction purposes.
Andhra Pradesh and Karnataka are two states located on the Deccan Plateau. Historically, the people of these states have utilized the volcanic rocks found in the region to build magnificent temples. The use of these rocks is evident in the construction of numerous temples, including the famous temples of Hampi in Karnataka and the temples of the Vijayanagara Empire. The volcanic rocks provide a strong foundation and aesthetic appeal, making them ideal for the intricate carvings and designs typical of temple architecture in these regions.
The Deccan Plateau's geological history is marked by extensive volcanic activity during the Cretaceous and Deccan Traps periods. This activity resulted in the formation of vast layers of basaltic lava, which cooled and solidified into the volcanic rocks that are now a defining characteristic of the region. The volcanic rocks are not only used in temple construction but also in other forms of architecture and infrastructure.
It is important to distinguish the Deccan Plateau from other geographical features in India. The Indo-Gangetic Plains, for example, are located in the northern part of the country and are characterized by fertile alluvial soil deposited by the rivers of the region. The Thar Desert, located in the western part of India, is primarily composed of sand and gravel and does not have significant volcanic rock formations. Therefore, the Deccan Plateau is the correct physical division where volcanic rocks are used in temple construction in Andhra Pradesh and Karnataka.
