The huge volcanic plateau that extends through most of southern India is known as the Deccan Plateau. This a triangular shaped plateau that extends in southern India, it has elevation of 100 meters on the north and gets higher and reaches up to 1000 meters on the south. It represents a remnant of an ancient volcano.
The huge volcanic plateau that extends across most of southern india is known as the <u>Deccan plateau</u>.
<h3>Explanation:</h3>
The Deccan Plateau is a broad plateau in India which comprises most of the southern portion of the land. It is among three hill ranges and stretches over eight Indian states; in specific, the lands of Maharashtra, Telangana, Karnataka, Andhra Pradesh, Kerala and Tamil Nadu are on that plateau.
That plateau comprises 422,000 square kilometres (163,000 sq mi), 43% of India's landmass.
As the asthenosphere is a highly viscous layer of the earth and is a mechanically weaker and ductile region and is upper part of the earth and its depth range for 50 to 200 meters that is below the mid-oceanic ridges and its thickness depends on the temperature.
In some regions, the depth can be of 700 km, as the temperature increases at greater depths the rocks get deformed and thus rigid lithosphere begins to float on this layer and causes the movement of a tectonic plate.
