Deccan Deccan Flag of Zambia Category="Geography of India"Category="Plateaus"The Deccan Plateau is a vast plateau in India, encompassing most of Central and Southern India. The name Deccan is anglicised form of the Prakrit dakkhin, itself derived from the Sanskrit dakṣiṇa, meaning south. It comprises the whole of peninsular India south of the Vindhya range and has an elevation which ranges from 1,500 to 2,500 feet (450 to 750 m). It is bounded in the west by the Western Ghats and in the east by the Eastern Ghats. These two formations form one of the vertex of a triangle which encompasses the plateau with the Vindhya range forming the third side. This region is one of the most stable land masses of the world.

Geography

It lies south of the Indo-Gangetic plain. It is bounded by the Western Ghats in the west, the Eastern Ghats to the east, the Nilgiris in the south and the Satpura and Vindhya ranges in the north. The plateau elevation is about 500 m on average. It is composed of black volcanic Basalt soil. The chief crop is Cotton, however Sugarcane, Rice and other crops also common. Several Indian states cover parts of the Deccan: Maharashtra covers most of the northern plateau, and Chhattisgarh the northeast corner. Andhra Pradesh covers the east-central portion of the Deccan, and Karnataka the west-central and most of the southern portion of the plateau, with the southernmost portion in Tamil Nadu. The largest city in the Deccan is Hyderabad, south central India. Other major cities include Bangalore, the capital of Karnataka, and Nagpur, Pune, and Sholapur in Maharashtra.

The Godavari River and its tributaries, including the Indravati, drain most of the northern portion of the plateau, rising in the Western Ghats and draining east towards the Bay of Bengal. The Tungabhadra, Krishna River and its tributaries, including the Bhima River, which also run from west to east, drain the central portion of the plateau. The southernmost portion of the plateau is drained by the Kaveri River, which rises in the Western Ghats of Karnataka and bends south to break through the Nilgiri hills into Tamil Nadu, emptying into the Bay of Bengal.

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. Some paleontologists speculate that this eruption may have caused the extinction of the dinosaurs. During a period lasting many hundred of years there was a lot of volcanic activity in the region. The molten lava that erupted out of the volcanoes solidified into a hard rocky layer. Layer after layer was formed by the volcanic activity that lasted many hundreds of years, and when the volcanoes became extinct, they left a region of highlands with typically vast stretches of flat areas on top like a table. Hence it is also known as Table Top.

Typically the Deccan Plateau is made up of basalt. This is an extrusive igneous rock. Also in certain sections of the region, we can find granite, which is an intrusive igneous rock. The difference between these two rock types are basalt rock forms on eruption of lava, that is, outside a volcano, while granite forms inside a volcano, that is, when the volcano becomes extinct the lava solidifies inside the volcano itself.

The Deccan is rich in minerals. Primary mineral ores found in this region are mica and Iron ore in the Chhota Nagpur region, and diamonds, Gold and other metals in the Golconda region.

People

The Deccan is home to many languages and peoples. Bhil and Gond peoples live in the hills along the northern and northeastern edges of the plateau, and speak various languages that belong to both the Indo-European and Dravidian families of languages. Marathi, an Indo-Aryan language, is the main language of the north-western portion of the Deccan plateau. Urdu, Telugu, and Kannada, are the predominant languages of Andhra Pradesh and Karnataka respectively, they occupy the plateau. Tamil is the main language of the country to the south of the plateau, and Malayalam that of the hills and coast to the south-west. Moreover, the city of Hyderabad is an important centre of Urdu language in the Deccan; its surrounding areas also host a notable population of Urdu speakers.
