The plateau is primarily composed of Deccan Traps—one of Earth's largest volcanic features—formed by massive flood basalt eruptions ~66 million years ago (end-Cretaceous). This created the plateau's characteristic flat-topped hills and rich black cotton soil (regur).
It hosts critical ecosystems: dry deciduous forests sheltering tigers, elephants, leopards, and endemic species. Major peninsular rivers—Godavari, Krishna, Kaveri—originate here, supporting agriculture and millions of people.
Fertile soils and reliable rainfall make it a grain, cotton, and pulse basket. It anchors India's tech boom: Hyderabad, Bangalore, Chennai, Pune are major IT, manufacturing, and education hubs driving national growth.
