Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

Topographic prominence
–
It is a measure of the independence of a summit. A peaks key col is a point on this contour line. By convention, the prominence of Mount Everest, the Earths highest mountain, is taken to equal the elevation of its summit above sea level, if the peaks prominence is P metres, to get from the summit to any higher terrain one must descend at least P metres. Together with the convention for Mount Everest, this implies that the prominence of any island or continental highpoint is equal to its elevation above sea level, for every ridge connecting the peak to higher terrain, find the lowest point on the ridge. The key col is defined as the highest of these cols, the prominence is the difference between the elevation of the peak and the elevation of the key col. The following mental exercise may illustrate the meaning of topographic prominence, imagine you are standing at the top of a peak and imagine that an imaginary sea level rises to your feet. Now slowly lower the sea level and an imaginary island appears beneath your feet. Your island will grow and will merge with other islands that emerge, the parent peak may be either close or far from the subject peak. The summit of Mount Everest is the parent peak of Aconcagua at a distance of 17,755 km, the key col may also be close or far from the subject peak. The key col for Aconcagua is the Bering Strait at a distance of 13,655 km, the key col for the South Summit of Mount Everest is about 100 m distant. Prominence is interesting to many mountaineers because it is a measurement that is strongly correlated with the subjective significance of a summit. Peaks with low prominences are either subsidiary tops of some higher summit or relatively insignificant independent summits, peaks with high prominences tend to be the highest points around and are likely to have extraordinary views. Only summits with a sufficient degree of prominence are regarded as independent mountains, for example, the worlds second-highest mountain is K2. While Mount Everests South Summit is taller than K2, it is not considered an independent mountain because it is a subsummit of the main summit, many lists of mountains take topographic prominence as a criterion for inclusion, or cutoff. John and Anne Nuttalls The Mountains of England and Wales uses a cutoff of 15 m, in the contiguous United States, the famous list of fourteeners uses a cutoff of 300 ft /91 m. Also in the U. S.2000 feet of prominence has become a threshold that signifies that a peak has major stature. This generates lists of peaks ranked by prominence, which are different from lists ranked by elevation. Such lists tend to emphasize isolated high peaks, such as range or island high points, one advantage of a prominence-ranked list is that it needs no cutoff, since a peak with high prominence is automatically an independent peak

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Malayalam
–
Malayalam /mʌləˈjɑːləm/ is a language spoken in India, predominantly in the state of Kerala. It is one of the 22 scheduled languages of India and was designated as a Classical Language in India in 2013 and it was developed to the current form mainly by the influence of the poet Thunchaththu Ezhuthachan in the 16th century. Malayalam has official status in the state of Kerala and in the union territories of Lakshadweep. It belongs to the Dravidian family of languages and is spoken by some 38 million people, according to one theory, Malayalam originated from Middle Tamil in the 7th century. However, the current understanding proposes the separation of Malayalam from Proto-Dravidian in the pre-historic era, Malayalam incorporated many elements from Sanskrit through the ages. Before Malayalam came into being, Old Tamil was used in literature and courts of a region called Tamilakam, including present day Kerala state, silappatikaramit was written by Chera prince Ilango Adigal from Chunkaparra, and is considered a classic in Sangam literature. Modern Malayalam still preserves many words from the ancient Tamil vocabulary of Sangam literature, the earliest script used to write Malayalam was the Vatteluttu alphabet, and later the Kolezhuttu, which derived from it. As Malayalam began to borrow words as well as the rules of grammar from Sanskrit. This developed into the modern Malayalam script, many medieval liturgical texts were written in an admixture of Sanskrit and early Malayalam, called Manipravalam. The oldest literary work in Malayalam, distinct from the Tamil tradition, is dated from between the 9th and 11th centuries, the first travelogue in any Indian language is the Malayalam Varthamanappusthakam, written by Paremmakkal Thoma Kathanar in 1785. Due to its lineage deriving from both Tamil and Sanskrit, the Malayalam script has the largest number of letters among the Indian language orthographies, the Malayalam script includes letters capable of representing almost all the sounds of all Indo-Aryan and Dravidian languages. Malayalam serves as a language on the islands including the Mahl-dominated Minicoy Island. The word Malayalam originated from the Sanskrit resp, Malayalam words malai or mala, meaning hill, and elam, meaning region. Malayalam thus translates as hill region and used to refer to the land of the Chera dynasty, the language Malayalam is alternatively called Alealum, Malayalani, Malayali, Malean, Maliyad, and Mallealle. The word Malayalam originally meant only for the name of the region, Malayanma or Malayayma represented the language. With the emergence of modern Malayalam language, the name of the language started to be known by the name of the region, hence now, the word Malayanma is considered by some to represent the olden Malayalam language. The language got the name Malayalam during the mid 19th century, the origin of Malayalam, an independent offshoot of the proto-Dravidian language, has been and continues to be an engaging pursuit among comparative historical linguists. Together with Tamil, Toda, Kannada and Tulu, Malayalam belongs to the group of Dravidian languages

Tamil language
–
Tamil is a Dravidian language predominantly spoken by the Tamil people of India and Sri Lanka, and also by the Tamil diaspora, Sri Lankan Moors, Burghers, Douglas, and Chindians. Tamil is a language of two countries, Singapore and Sri Lanka. It has official status in the Indian state of Tamil Nadu and it is also used as one of the languages of education in Malaysia, along with English, Malay and Mandarin. Tamil is also spoken by significant minorities in the four other South Indian states of Kerala, Karnataka, Andhra Pradesh and Telangana and it is one of the 22 scheduled languages of India. Tamil is one of the classical languages in the world. Tamil-Brahmi inscriptions from 500 BC have been found on Adichanallur and 2 and it has been described as the only language of contemporary India which is recognizably continuous with a classical past. The variety and quality of classical Tamil literature has led to it being described as one of the classical traditions. A recorded Tamil literature has been documented for over 2000 years, the earliest period of Tamil literature, Sangam literature, is dated from ca.300 BC – AD300. It has the oldest extant literature among other Dravidian languages, the earliest epigraphic records found on rock edicts and hero stones date from around the 3rd century BC. More than 55% of the inscriptions found by the Archaeological Survey of India are in the Tamil language. Tamil language inscriptions written in Brahmi script have been discovered in Sri Lanka, the two earliest manuscripts from India, acknowledged and registered by the UNESCO Memory of the World register in 1997 and 2005, were written in Tamil. In 1578, Portuguese Christian missionaries published a Tamil prayer book in old Tamil script named Thambiraan Vanakkam, the Tamil Lexicon, published by the University of Madras, was one of the earliest dictionaries published in the Indian languages. According to a 2001 survey, there were 1,863 newspapers published in Tamil, Tamil belongs to the southern branch of the Dravidian languages, a family of around 26 languages native to the Indian subcontinent. It is also classified as being part of a Tamil language family, the closest major relative of Tamil is Malayalam, the two began diverging around the 9th century CE. According to linguists like Bhadriraju Krishnamurti, Tamil, as a Dravidian language, descends from Proto-Dravidian, linguistic reconstruction suggests that Proto-Dravidian was spoken around the third millennium BC, possibly in the region around the lower Godavari river basin in peninsular India. The material evidence suggests that the speakers of Proto-Dravidian were of the associated with the Neolithic complexes of South India. The next phase in the reconstructed proto-history of Tamil is Proto-South Dravidian, the linguistic evidence suggests that Proto-South Dravidian was spoken around the middle of the second millennium BC, and that proto-Tamil emerged around the 3rd century BC. The earliest epigraphic attestations of Tamil are generally taken to have been shortly thereafter

Kerala
–
Kerala historically known as Keralam, is an Indian state in South India on the Malabar Coast. It was formed on 1 November 1956 following the States Reorganisation Act by combining Malayalam-speaking regions, spread over 38,863 km2, it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33,387,677 inhabitants as per the 2011 Census, Malayalam is the most widely spoken language and is also the official language of the state. The region has been a prominent spice exporter since 3000 BCE, the Chera Dynasty was the first prominent kingdom based in Kerala, though it frequently struggled against attacks by the neighbouring Cholas and Pandyas. In the 15th century, the spice trade attracted Portuguese traders to Kerala, after independence, Travancore and Cochin joined the Republic of India and Travancore-Cochin was given the status of a state in 1949. In 1956, Kerala state was formed by merging Malabar district, Travancore-Cochin, Hinduism is practised by more than half of the population, followed by Islam and Christianity. The culture is a synthesis of Aryan and Dravidian cultures, developed over millennia, under influences from other parts of India, the production of pepper and natural rubber contributes significantly to the total national output. In the agricultural sector, coconut, tea, coffee, cashew, the states coastline extends for 595 kilometres, and around 1.1 million people in the state are dependent on the fishery industry which contributes 3% to the states income. The state has the highest media exposure in India with newspapers publishing in nine languages, mainly English, Kerala is one of the prominent tourist destinations of India, with backwaters, beaches, Ayurvedic tourism and tropical greenery as its major attractions. The name Kerala has an uncertain etymology, One popular theory derives Kerala from Kera and alam is land, thus land of coconuts, this also happens to be a nickname for the state due to abundance of coconut trees and its use by the locals. The word Kerala is first recorded in a 3rd-century BCE rock inscription left by the Maurya emperor Ashoka, the inscription refers to the local ruler as Keralaputra, or son of Chera. This contradicts the theory that Kera is from coconut tree, at that time, one of three states in the region was called Cheralam in Classical Tamil, Chera and Kera are variants of the same word. The word Cheral refers to the oldest known dynasty of Kerala kings and is derived from the Proto-Tamil-Malayalam word for lake, the earliest Sanskrit text to mention Kerala is the Aitareya Aranyaka of the Rigveda. It is also mentioned in the Ramayana and the Mahabharata, the two Hindu epics, the Skanda Purana mentions the ecclesiastical office of the Thachudaya Kaimal who is referred to as Manikkam Keralar, synonymous with the deity of the Koodalmanikyam temple. Keralam may stem from the Classical Tamil cherive-alam or chera alam, the Greco-Roman trade map Periplus Maris Erythraei refers to Keralaputra as Celobotra. According to Hindu mythology, the lands of Kerala were recovered from the sea by the warrior sage Parasurama. Parasurama threw his axe across the sea, and the water receded as far as it reached, according to legend, this new area of land extended from Gokarna to Kanyakumari. The land which rose from sea was filled with salt and unsuitable for habitation, so Parasurama invoked the Snake King Vasuki, out of respect, Vasuki and all snakes were appointed as protectors and guardians of the land
