Kerala - Geography

Geography

The state is wedged between the Lakshadweep Sea and the Western Ghats. Lying between north latitudes 8°18' and 12°48' and east longitudes 74°52' and 77°22', Kerala experiences the humid equatorial tropic climate. The state has a coast of 590 km (370 mi) and the width of the state varies between 11 and 121 km (22–75 miles). Geographically, Kerala can be divided into three climatically distinct regions: the eastern highlands; rugged and cool mountainous terrain, the central midlands; rolling hills, and the western lowlands; coastal plains. The state is located at the extreme southern tip of the Indian subcontinent and lies near the centre of the Indian tectonic plate; hence, it is subject to comparatively low seismic and volcanic activity. Pre-Cambrian and Pleistocene geological formations compose the bulk of Kerala’s terrain. A catastrophic flood in Kerala in 1341 CE drastically modified its terrain and consequently affected its history; it also created a natural harbor for spice transport.

The eastern region of Kerala consists of high mountains, gorges and deep-cut valleys immediately west of the Western Ghats' rain shadow. Forty-one of Kerala’s west-flowing rivers, and three of its east-flowing ones originate in this region. The Western Ghats form a wall of mountains interrupted only near Palakkad; hence also known Palghat, where the Palakkad Gap breaks through to provide access to the rest of India. The Western Ghats rise on average to 1,500 m (4920 ft) above sea level, while the highest peaks reach around 2,500 m (8200 ft). Anamudi, the highest peak in south India, is at an elevation of 2,695 metres (8,842 ft). The elevations of the eastern portions of the Nilgiri Hills and Palni Hills range from 250 and 1,000 m (820 and 3300 ft).

Kerala’s western coastal belt is relatively flat to the eastern region, and is criss-crossed by a network of interconnected brackish canals, lakes, estuaries, and rivers known as the Kerala Backwaters. The state's largest lake Vembanad, dominates the Backwaters; it lies between Alappuzha and Kochi and is more than 200 km2 (77 sq mi) in area. Around 8% of India's waterways are found in Kerala. Kerala’s forty-four rivers include the Periyar; 244 km, Bharathapuzha; 209 km, Pamba; 176 km, Chaliyar; 169 km, Kadalundipuzha; 130 km, Valapattanam; 129 km and the Achankovil River; 128 km. The average length of the rivers is 64 km. Many of the rivers are small and entirely fed by monsoon rain. As Kerala's rivers are small and lacking in delta, they are more prone to environmental effects. The rivers face problems such as sand mining and pollution. The state experiences several natural hazards like landslides, floods, lightning and droughts; the state was also affected by the 2004 Indian Ocean Tsunami.

Famous quotes containing the word geography:

    The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.
    Willard Van Orman Quine (b. 1908)

    Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.
    Henry David Thoreau (1817–1862)

    Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.
    Ralph Waldo Emerson (1803–1882)
