The word ghati means valley. In Marathi, Hindi, Gujarati and Kannada, ghat is a term used to identify a difficult passage over a mountain. One such passage is the Bhor Ghat that connects the towns Khopoli and Khandala, on NH 4 about north of Mumbai. Charmadi Ghat of Karnataka is also notable. In many cases, the term is used to refer to a mountain range itself, as in the Western Ghats and Eastern Ghats. 'Ghattam' in Malayalam also refers to mountain ranges when used with the name of the ranges being addressed, while the passage road would be called a 'churam'. Eastern Ghats on the east coast of India and Western Ghats on the west coast of India are the largest ghats in pensular India. Western Ghats, also known as Sahyadri, is a mountain range covers an area of 140,000 km² in a stretch of 1,600 km parallel to the western coast of the Indian peninsula, traverse the States of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat. It is a UNESCO World Heritage Site and is one of the eight "hottest hot-spots" of biological diversity in the world. It is sometimes called the Great Escarpment of India.. It is a biodiversity hotspot that contains a large proportion of the country's flora and fauna; many of which are only found here and nowhere else in the world. According to UNESCO, Western Ghats are older than Himalayan mountains. It also influences Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty-nine properties including national parks, wildlife sanctuaries and reserve forests were designated as world heritage sites - twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra. Ghati people, literally means the people of hills or ghats , is an exonym used for the marathi people specially those from the villages in Western Ghats, often in pejorative terms. The Eastern Ghats are a discontinuous range of mountains along India's eastern coast. The Eastern Ghats run from the northern Odisha through Andhra Pradesh to Tamil Nadu in the south passing some parts of Karnataka and in the Wayanad region of Kerala. They are eroded and cut through by four major rivers of peninsular India, viz. Godavari, Mahanadi, Krishna, and Kaveri. The mountain ranges run parallel to the Bay of Bengal. The Deccan Plateau lies to the west of the range, between the Eastern Ghats and the Western Ghats. The coastal plains, including the Coromandel Coast region, lie between the Eastern Ghats and the Bay of Bengal. The Eastern Ghats are not as high as the Western Ghats. The Eastern Ghats are older than the Western Ghats, and have a complex geologic history related to the assembly and breakup of the ancient supercontinent of Rodinia and the assembly of the Gondwana supercontinent. The Eastern Ghats are made up of charnockites, granite gneiss, khondalites, metamorphicgneisses and quartziterock formations. The structure of the Eastern Ghats includes thrusts and strike-slip faults all along its range. Limestone, bauxite and iron ore are found in the Eastern Ghats hill ranges.
River ghats
The numerous significant ghats along the Ganges are the Varanasi ghats and generically the "ghats of the Ganges". Most of these were constructed under the patronage of various Maratha rulers such as Ahilyabai Holkar in the 18th century. In Madhya Pradesh in central India there are further significant ghats along the Narmada River. People who live on the steps are also called ghats.
Shmashana - the cremation ghats
Ghats such as these are useful for both mundane purposes and religious rites ; there are also specific "shmashana" or "cremation" ghats where bodies are cremated waterside, allowing ashes to be washed away by rivers; notable ones are Nigambodh Ghat and Raj Ghat in Delhi on the Yamuna, the latter of which was the cremation area for Mohandas Karamchand Gandhi and numerous political leaders after him, and the Manikarnika Ghat at Varanasi on the Ganges.
