Model Questions & Answers (Q41–60)
Q41. Explain the geological structure of the Peninsular Plateau.
Answer: The Peninsular Plateau is composed of ancient crystalline igneous and metamorphic rocks of the Precambrian era. It is part of the Gondwana landmass and is tectonically stable.

Q43. Explain the formation of the Deccan Trap.
Answer: The Deccan Trap was formed by extensive volcanic eruptions during the late Cretaceous period, resulting in layered basaltic lava flows.

Q45. Differentiate between Western Ghats and Eastern Ghats.
Answer: Western Ghats are continuous, higher, and form a steep escarpment; Eastern Ghats are discontinuous, lower, and dissected by rivers.
Answer: Western Ghats are continuous, higher, and form a steep escarpment; Eastern Ghats are discontinuous, lower, and dissected by rivers.
Q46. Explain the drainage pattern of Peninsular rivers.
Answer: Peninsular rivers follow a dendritic pattern and flow eastward (Godavari, Krishna, Cauvery) due to slope, while Narmada and Tapi flow westward in rift valleys.
Answer: Peninsular rivers follow a dendritic pattern and flow eastward (Godavari, Krishna, Cauvery) due to slope, while Narmada and Tapi flow westward in rift valleys.
Q47. Discuss rift valley formation in Peninsular India.
Answer: Narmada and Tapi rivers flow through rift valleys formed due to faulting and block movements.
Answer: Narmada and Tapi rivers flow through rift valleys formed due to faulting and block movements.
Q48. Explain black soil formation in Deccan Plateau.
Answer: Black soil (Regur) is formed from weathering of basaltic rocks. It is rich in iron, magnesium and suitable for cotton cultivation.
