Deccan Trap is associated with which natural process?
Answer and explanation
Correct answer: Volcanic lava flow
The correct answer is A, volcanic lava flow. The Deccan Trap is a vast basaltic formation produced by repeated outpourings of fluid lava through fissures during ancient volcanic activity. As successive lava sheets cooled and solidified, they created step-like layers; the word trap comes from a term associated with stairs. Later weathering of this basalt contributed to the formation of black cotton soil in much of the Deccan region. Glacial erosion produces features such as U-shaped valleys, sea-wave deposition affects coastal areas, and desert dust forms aeolian deposits. None of those processes explains the layered basalt of the Deccan Trap.
