Geography
Tamil Nadu covers an area of 130,058 km2 (50,216 sq mi), and is the eleventh largest state in India. The bordering states are Kerala to the west, Karnataka to the north west and Andhra Pradesh to the north. To the east is the Bay of Bengal and the union territory of Puducherry. The southernmost tip of the Indian Peninsula is located in Tamil Nadu. At this point is the town of Kanyakumari which is the meeting point of the Arabian Sea, the Bay of Bengal, and the Indian Ocean. The south boundary of India is Kanyakumari, Tamil Nadu.
The western, southern and the north western parts are hilly and rich in vegetation. The Western Ghats and the Eastern Ghats meet at the Nilgiri hills. The Western Ghats dominate the entire western border with Kerala, effectively blocking much of the rain bearing clouds of the south west monsoon from entering the state. The eastern parts are fertile coastal plains and the northern parts are a mix of hills and plains. The central and the south central regions are arid plains and receive less rainfall than the other regions.
Tamil Nadu has a coastline of about 910 km (570 mi) which is the country's third longest coastline. Tamil Nadu's coastline bore the brunt of the 2004 Indian Ocean Tsunami when it hit India, which caused 7,793 direct deaths in the state. Tamil Nadu falls mostly in a region of low seismic hazard with the exception of the western border areas that lie in a low to moderate hazard zone; as per the 2002 Bureau of Indian Standards (BIS) map, Tamil Nadu falls in Zones II & III. Historically, parts of this region have experienced seismic activity in the M5.0 range.

The Gymnosperm diversity of the country is 64 species of which Tamil Nadu has four indigenous species and about 60 introduced species. The Pteridophytes diversity of India includes 1022 species of which Tamil Nadu has about 184 species. Vast numbers of bryophytes, lichen, fungi, algae and bacteria are among the wild plant diversity of Tamil Nadu.
Common plant species include the state tree: Palmyra Palm, Eucalyptus, Rubber, Cinchona, Clumping Bamboos (Bambusa Arundinacea), Common teak, Anogeissus latifolia, Indian Laurel, Grewia, and blooming trees like Indian labumusum, Ardisia, and Solanaceae.

Climate
A semi-arid wasteland near Tirunelveli. Monsoon clouds pour torrents of rain on windward-facing Kerala, but are prevented from reaching Tirunelveli by the Agasthyamalai Range of the Western Ghats (background).
Tamil Nadu is mostly dependent on monsoon rains, and thereby is prone to droughts when the monsoons fail. The climate of the state ranges from dry sub-humid to semi-arid. The state has three distinct periods of rainfall:
advancing monsoon period, south west monsoon from June to September, with strong southwest winds;
North east monsoon from October to December, with dominant north east winds;
dry season from January to May.
The annual rainfall of the state is about 945 mm (37.2 in) of which 48 per cent is through the north east monsoon, and 32 per cent through the south west monsoon. Since the state is entirely dependent on rains for recharging its water resources, monsoon failures lead to acute water scarcity and severe drought.
Tamil Nadu is divided into seven agro-climatic zones: north east, north west, west, southern, high rainfall, high altitude hilly, and Cauvery Delta (the most fertile agricultural zone). The table below shows the maximum and minimum temperatures that the state experiences in the plains and hills.

Scheduled castes and Scheduled tribes comprise 19 per cent and 1 per cent of the population respectively. Though an overwhelming percentage of SC/ST population identify themselves as Hindu, the SC/STs are enumerated separately in the census and not as a subgroup of Hinduism. An anti-conversion law came into force in 2002. However, the law was repealed in June 2004 after the defeat of the Bharatiya Janata Party led coalition in the 2004 elections.
