Deccan Peninsula has the highest land coverage in India.

The Deccan Peninsula is a vast region located in southern India, encompassing the states of Maharashtra, Karnataka, Andhra Pradesh, Telangana, and parts of Tamil Nadu and Kerala. It is known for its extensive land coverage, making it the largest biogeographical region in India. Several factors contribute to the high land coverage of the Deccan Peninsula.

1. Geographical Extent:
The Deccan Peninsula covers a significant portion of the Indian subcontinent, extending from the Western Ghats in the west to the Eastern Ghats in the east. It spans approximately 1.8 million square kilometers, accounting for a substantial land area in India.

2. Plateau Region:
The Deccan Peninsula is characterized by the Deccan Plateau, which is a vast elevated landmass. The plateau is formed by multiple layers of volcanic lava flows, resulting in a relatively flat and expansive terrain. This plateau region contributes to the substantial land coverage of the Deccan Peninsula.

3. Rivers and Watersheds:
Several major rivers flow through the Deccan Peninsula, including the Godavari, Krishna, Tungabhadra, and Kaveri. These rivers and their tributaries have formed extensive watersheds, which further add to the land area of the region. The presence of these rivers and watersheds contributes to the high land coverage of the Deccan Peninsula.

4. Biodiversity Hotspot:
The Deccan Peninsula is a hotspot of biodiversity, with a wide range of ecosystems and habitats. It is home to several national parks, wildlife sanctuaries, and reserve forests, which further increase the land coverage. The presence of diverse flora and fauna in the region contributes to its high land coverage.

In conclusion, the Deccan Peninsula has the highest land coverage in India due to its geographical extent, the presence of the Deccan Plateau, rivers and watersheds, and its status as a biodiversity hotspot.
