A tropical deciduous plant special to the Deccan Plateau is
(a) Teak
(b) Shisam
(c) Sandalwood
(d) Sal
Solution: (c)
Teak, Sal, Sandalwood, Shisham and Mahua are some of the tropical deciduous trees that extend from the Shiwalik ranges in the north to the eastern flanks of the Western Ghats in the peninsular India. Among them, sandalwood is native to the Deccan plateau. The total extent of its distribution is approximately 9000 km2 of which 8200 km2 is located in the states of Karnataka and Tamil Nadu. It grows particularly in Mysore and Coimbatore where it prefers hard rock, ferruginous soil—the conditions that produce a richer scent in the tree.

The Malwa Plateau roughly forms a triangle based on the Vindhyan Hills, bounded by the Aravalli Range in the west and Madhya Bharat Pathar to the north and Bundelkhand to the east. It has two systems of drainage; one towards the Arabian sea (The Narmada, the Tapi and the Mahi), and the other towards the Bay of Bengal (Chambal and Betwa, joining the Yamuna).
