Odisha lies on the eastern coast of India. It is bounded by West Bengal in northeast, Jharkhand in the north, Madhya Pradesh in the west, 
Andhra Pradesh in the south, and the Bay of Bengal in the east. Orissa can be divided into three broad regions – the coastal plains, the middle mountainous country and the plateaus. The region of the coastal plains is a combination of several deltas formed by the major rivers of Odisha, such as the Subarnarekha, the Budhabalanga, the Baitarani, the Brahmani, the Mahanadi, and the Rushikulya. The middle mountainous region covers about three-fourths of the entire state and comprises the hills and mountains of the Eastern Ghats. The plateaus are mostly eroded tablelands, forming the western slopes of the Eastern Ghats. To sum up, the state offers diverse habitats from lush green and hilly terrain, to coastal plains and rolling river valleys, criss-crossed by rivers that include the Brahmani, the Mahanadi and the Bansadhara.
