significance of decan trap in India ( 5 Mark)
Answers
Answer:
The Deccan Traps, one of the Earth's largest igneous provinces, cover over 500,000 km2 of west-central India. Erupted about 66 million years during the extinction of the dinosaurs, these flood basalts, in cooperation with the sea, rains and rivers, have shaped the landscape of west-central India.

Answer:
The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth. They consist of multiple layers of solidified flood basalt that together are more than 2,000 m (6,600 ft) thick, cover an area of c. 500,000 km2 (200,000 sq mi),[1] and have a volume of c. 1,000,000 km3 (200,000 cu mi).[2] Originally, the Deccan Traps may have covered c. 1,500,000 km2 (600,000 sq mi),[3] with a correspondingly larger original volume.
Explanation:
The Deccan Traps began forming 66.25 million years ago,[3] at the end of the Cretaceous period. The bulk of the volcanic eruption occurred at the Western Ghats some 66 million years ago. This series of eruptions may have lasted fewer than 30,000 years.[5]
The original area covered by the lava flows is estimated to have been as large as 1.5 million km2 (0.58 million sq mi), approximately half the size of modern India. The Deccan Traps region was reduced to its current size by erosion and plate tectonics; the present area of directly observable lava flows is around 500,000 km2 (200,000 sq mi).
