Geography of India
Bodies of water
Major gulfs include the Gulf of Cambay, Gulf of Kutch and the Gulf of Mannar. Straits include the Palk Strait which separates India from Sri Lanka and the Ten Degree Channel, separating the Andamans from the Nicobar Islands and the Eight Degree Channel separating the Laccadive and Amindivi Islands from Minicoy Island towards the south. Important capes include the Cape Comorin, the southern tip of mainland India, Indira Point, the southernmost location of India, Rama’s Bridge and Point Calimere.
Smaller seas include the Laccadive Sea and the Andaman Sea. There are four coral reefs in India and are located in; the Andaman and Nicobar Islands, Gulf of Mannar, Lakshadweep and Gulf of Kutch.
Important lakes include Chilka Lake, the country’s largest salt-water lake in Orissa; Kolleru Lake in Andhra Pradesh; Loktak Lake in Manipur, Dal Lake in Kashmir, Sambhar Lake in Rajasthan, and the Sasthamkotta Lake in Kerala.
Wetlands
India’s wetland ecosystem is widely distributed from the cold and arid; from ones in the Ladakh region in the state of Jammu and Kashmir to the ones in the wet and humid climate of peninsula India. Most of the wetlands are directly or indirectly linked to India’s river networks. The Indian government has identified a total of 22 wetlands for conservation. Among the protected wetlands are the tropical mangrove forests in peninsular India and the salt mudflats in western India.
Mangrove forests occur all along the Indian coastline, in sheltered estuaries, creeks, backwaters, salt marshes and mud flats. The mangrove area covers a total of 6,740 km² (2,600 mile²) which comprises 7 percent of the world’s total mangrove cover. The Andaman and Nicobar Islands; the Sundarbans; Gulf of Kutch; deltas of the Mahanadi, Godavari and Krishna; and parts of Maharashtra, Karnataka and Kerala have large mangrove covers.
Most of the identified wetlands adjoin or are parts of sanctuaries, national parks and are thus protected.
The Sundarbans
The Sundarbans delta is the largest mangrove forest in the world. It lies at the mouth of the Ganges and is spread across areas of Bangladesh and West Bengal, India. The Bangladeshi and Indian portions of the jungle are listed in the UNESCO world heritage list separately as the Sundarbans and Sundarbans National Park respectively, though they are parts of the same forest. The Sundarbans are intersected by a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests, and presents an excellent example of ongoing ecological processes.
The area is known for its wide range of fauna. The most famous among these is the Bengal Tiger, but numerous species of birds, spotted deer, crocodiles and snakes also inhabit it. It is estimated that there are now 400 Bengal tigers and about 30,000 spotted deer in the area.
Rann of Kutch
The Rann of Kutch is a marshy region located in the Gujarat state of India, which borders the Sindh region of Pakistan. The name Rann comes from the Hindi word ran meaning “salt marsh.” It occupies a total area of 27,900 km² (10,800 mile²)[5].
The region was originally a part of the Arabian Sea. Geologic forces, most likely by earthquakes, resulted in the damming up of the region, turning it into a large salt-water lagoon. This area gradually filled with silt thus turning it into a seasonal salt marsh. During the monsoons, the area turns into a shallow marsh, often flooding to knee-depth height. After the monsoons, the region turns dry and becomes parched.
Climate
India’s climate is strongly influenced by the Himalayas and the Thar Desert. The Himalayas, along with the Hindu Kush mountains in Pakistan, provide a barrier to the cold winds from central Asia. This keeps most of the Indian subcontinent warmer than most locations in similar latitudes. The Thar Desert is responsible for attracting the moisture laden monsoon winds that provide most of India’s rainfall.
It is difficult to generalise India’s climate. India’s huge size sees climatic conditions in Kashmir having little relation to that in the extreme south. In addition to this, the varied topography of the land sees many regions having their own microclimates. Climate in India ranges from tropical in the south to a temperate climate in the north. Parts of India in the Himalayas have a polar climate.
Meteorologists divide the year into four main seasons for most of the country: monsoon, summer, winter and withdrawal of the monsoons. Parts of India that lie in the Himalayan region see five seasons: spring, summer, monsoons, autumn and winter. Sustained snowfalls occur only in the elevated sections.
Summer lasts between March and June in most parts of India. Temperatures exceed 40 °C (104 °F) during the day. The coastal regions exceed 30 °C (86 °F) coupled with high levels of humidity. In the Thar desert area temperatures can exceed 45 °C (113 °F).
