It spreads from Satpuda, Mahadev and Maikal ranges in north up to the southern tip of the peninsular India. It is one of the parts of Peninsular Plateau.
The north-western parts of the plateau are composed of lava deposits.
The Western Ghats from the western boundary of Deccan Plateau, while the Eastern Ghats from its eastern boundary.
The Western Ghats run north-south along the Arabian Sea Coast. It has several local names.
Western Ghats is known as ‘Sahyadri’ in Maharashtra and Karnataka. It is known as ‘Nilgiri’ in Tamil Nadu.
On the border of Kerala and Tamil Nadu, it is known as Annamalai and in further south, it is known as Cardamum Hills.
The southern portion of Weatem Ghats is loftier.
The average height of Deccan Plateau range between $900$ to $1000$ metres. At few places the height is even more.
A few isolate hills having more than $900$ metres of height forms the eastern boundary of this plateau. These hills together are called ‘Eastern Ghats’.
Except rivers Narmada and Tapi which flow westwards and meet Arabian Sea, most of the rivers of Deccan Plateau flow eastwards and meet Bay of Bengal.
From this, it is evident that Eastern Ghats have a gentle slope towards south-east.
