How does the landscape of Himalaya differ from that of the Deccan Plateau ?

Answer 1

One is a mountain range!(Himalayas)
Another is a plateau!(Deccan Plateau)

Also Deccan Plateau is one of the oldest Landforms on the earth ageing about 4 billion years!!
The vast volcanic basalt beds of the Deccan were laid down in the massive Deccan Traps eruption, which occurred at the end of the Cretaceous period, 65 million years ago.
It makes up large areas of Maharashtra, Karnataka and parts of Andhra Pradesh south of the Vindhya range and has an elevation which ranges from 100 metres in the north to 1000 metres in the south. It is bounded in the west by the Western Ghats and in the east by the Eastern Ghats.



Himalayas are about 70-50 millin years old mountain formed due to tectonic plate collision.
The Himalaya range runs for about 2,400 km, from Nanga Parbat in the west to Namche Barwa in the east. The width varies between 250-300 km. The Himalayan range comprises three parallel ranges, arranged by elevation and geological age.

Answer 2

The Deccan Plateau is an elevated area making up the whole of the southern India tableland and extenting over eight states.[1] It is a vast plateau lying east of the Western Ghats.
In laymans terms it is not exactually a mountainious area but an elevated land area covering thousands of square miles.
In geology and earth science, a plateau, also called a high plateau or tableland, is an area of highland, usually consisting of relatively flat open country.




The Himalayas \), also Himalaya are a mountain range in Asia, separating the Indian subcontinent from the Tibetan
