The Chota Nagpur Plateau marks the eastern limit.
Which rivers drain the Central Highlands?
This region is drained by rivers that are tributaries of the Ganga and the Yamuna.

How does the Deccan Plateau slope?
The Deccan Plateau slopes gently towards the east.
What is the elevation range of the Deccan Plateau?
The elevation ranges from 300 m to 900 m.
What natural feature is formed as rivers plunge from the edge of the plateaus?
A number of waterfalls are formed, e.g., Jog Falls.
What marks the eastern border of the Deccan Plateau?
The eastern border is marked by the Eastern Ghats.
How do the Eastern Ghats differ from the Western Ghats?
The Eastern Ghats are low hills isolated from one another, unlike the continuous Western Ghats.
What is the elevation of the Eastern Ghats?
The elevation of these hills does not normally exceed 1,000 m.
Where do the Eastern and Western Ghats meet?
They meet in the Nilgiri Hills, popularly called the Blue Mountains.
What is the Deccan Trap Region?

What type of soil covers the Deccan Plateau?
The volcanic rocks have been severely eroded to form fertile black soil.
