how is deccan plateau formed

1. What is the Deccan Plateau?

The Deccan Plateau is a large elevated region located in central and southern India. It covers an area of approximately 1.9 million square kilometers and is one of the oldest and most stable landforms on Earth.

2. How was the Deccan Plateau formed?

The Deccan Plateau was formed by volcanic activity millions of years ago. The plateau is primarily made up of thick layers of solidified basaltic lava flows, which were extruded from the earth’s mantle through cracks in the continental crust.

3. What are the main features of the Deccan Plateau?

The main features of the Deccan Plateau include its extensive lava plateaus, rugged terrain, dissected plateaus, and numerous hills and mountains. It is also known for its vast basalt rock formations, such as the famous columnar joints found at places like the Rajmachi Fort and Devil’s Kitchen.

4. How old is the Deccan Plateau?

The volcanic activity that formed the Deccan Plateau started around 66 million years ago during the late Cretaceous period. The lava flows continued for several million years, finally ceasing around 63 million years ago.

5. What factors contributed to the formation of the Deccan Plateau?

The formation of the Deccan Plateau can be attributed to the eruption of the massive Deccan Traps, a large igneous province. The eruption was triggered by the upwelling of molten rock or magma from the mantle beneath the Indian continental crust.

6. How did the Deccan Traps eruptions occur?

The Deccan Traps eruptions were mostly of the flood basalt type, characterized by the outpouring of huge volumes of basaltic lava over a relatively short period. These eruptions were likely caused by hotspot activity or plume-induced crustal deformation.

7. What is the geological significance of the Deccan Plateau?

The Deccan Plateau holds great geological significance as it provides valuable insights into the Earth’s history, past volcanic activity, and the environmental changes that occurred during the formation of the Indian subcontinent. The rocks found on the plateau preserve a record of the ancient eruptions and subsequent weathering processes.

14. How has the Deccan Plateau influenced tourism?

The Deccan Plateau’s unique geological formations, scenic landscapes, and historical sites have made it a popular tourist destination. It offers opportunities for nature tourism, trekking, wildlife safaris, exploring ancient caves and cave temples, and experiencing the rich cultural heritage of the region.

15. What are the major national parks and wildlife sanctuaries on the Deccan Plateau?

The Deccan Plateau is home to several national parks and wildlife sanctuaries, including Bandipur National Park, Nagarhole National Park, Tadoba Andhari Tiger Reserve, Pench National Park, and Manyee Wildlife Sanctuary. These protected areas provide habitats for various endangered and endemic species.

16. How has the Deccan Plateau affected regional climate?

The Deccan Plateau’s elevated topography significantly influences the regional climate. It acts as a barrier to the southwest monsoon winds, causing the rainfall to decrease as it moves further inland. This results in a semi-arid to arid climate in certain parts of the plateau.

17. What are the major challenges faced by the Deccan Plateau region?

The Deccan Plateau region faces several challenges, including water scarcity, deforestation, soil erosion, unsustainable land use practices, and loss of biodiversity. Addressing these issues requires sustainable management practices and conservation efforts.

18. How are the people of the Deccan Plateau adapting to changing environmental conditions?

The people of the Deccan Plateau have been adapting to changing environmental conditions by adopting water conservation techniques, organic farming practices, afforestation initiatives, and promoting sustainable tourism. These measures aim to mitigate the impact of climate change and ensure a more sustainable future.

19. Has the Deccan Plateau experienced any recent volcanic activity?

No, the Deccan Plateau has been inactive in terms of volcanic activity for millions of years. However, remnants of its volcanic past can still be observed in the form of volcanic rock formations and geothermal activity in certain areas.

20. Are there any famous landmarks or tourist attractions on the Deccan Plateau?

Yes, the Deccan Plateau is home to several famous landmarks and tourist attractions. Some notable ones include the historical city of Hampi, Golconda Fort, Ajanta and Ellora Caves, Jog Falls, Western Ghats UNESCO World Heritage Site, and the hill stations of Ooty and Mahabaleshwar.
