supports: An oak is a tree or shrub in the genus Quercus (Latin "oak tree") of the beech family, Fagaceae. There are approximately 600 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably "Lithocarpus" (stone oaks), as well as in those of unrelated species such as "Grevillea robusta" (silky oaks) and the Casuarinaceae (she-oaks). The genus "Quercus" is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species. Sussex (abbreviated Sx), from the Old English "Sþsaxe" (South Saxons), is a historic county in South East England corresponding roughly in area to the ancient Kingdom of Sussex. It is bounded to the west by Hampshire, north by Surrey, north-east by Kent, south by the English Channel, and divided for local government into West Sussex and East Sussex and the city of Brighton and Hove. Brighton and Hove was created as a unitary authority in 1997, and granted City status in 2000. Until then, Chichester was Sussex's only city. The home counties are the counties of England that surround London (although several of them do not border it). The counties generally included in the list are Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, and Sussex. Other counties more distant from Londonsuch as Bedfordshire, Cambridgeshire, Hampshire and Oxfordshireare also sometimes regarded as home counties due to their proximity to London and their connection to the London regional economy. Dover is a town and major ferry port in the home county of Kent, in South East England. It faces France across the strait of Dover, the narrowest part of the English Channel, and lies south-east of Canterbury; east of Kent's county town Maidstone; and north-east along the coastline from Dungeness and Hastings. The town is the administrative centre of the Dover District and home of the Dover Calais ferry through the Port of Dover. The surrounding chalk cliffs are known as the White Cliffs of Dover. Swanley is a town and civil parish in the Sevenoaks District of Kent, England. It is located approximately southeast of central London, adjacent to the Greater London boundary and within the M25 motorway. The population at the 2011 census was 16,226. The local council is Swanley Town Council. Sevenoaks is a town and civil parish with a population of 29,506 situated in western Kent, England, south-east of London. The population of the civil parish had reduced to 20,409 at the 2011 Census. It is served by a commuter main line railway and is south-east of London Charing Cross. The town gives its name to the Sevenoaks district, of which it is the principal town, followed by Swanley and Edenbridge. Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert unique to chalk) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceous organisms as water is expelled upwards during compaction. Flint is often deposited around larger fossils such as Echinoidea which may be silicified (i.e. replaced molecule by molecule by flint). South East England is the most populous of the nine official regions of England at the first level of NUTS for statistical purposes. It consists of Berkshire, Buckinghamshire, East Sussex, Hampshire, the Isle of Wight, Kent, Oxfordshire, Surrey and West Sussex. As with the other regions of England, apart from Greater London, the south east has no elected government. Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. The White Cliffs of Dover are cliffs that form part of the English coastline facing the Strait of Dover and France. The cliffs are part of the North Downs formation. The cliff face, which reaches up to , owes its striking appearance to its composition of chalk accentuated by streaks of black flint. The cliffs stretch along the coastline for eight miles (13 km), spreading east and west from the town of Dover in the county of Kent, an ancient and still important English port. Greensand or Green sand is either a sand or sandstone, which has a greenish color. This term is specifically applied to shallow marine sediment, that contains noticeable quantities of rounded greenish grains. These grains are called "glauconies" and consist of a mixture of mixed-layer clay minerals, such as smectite and glauconite mica. Greensand is also loosely applied to any glauconitic sediment. Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color with very low weathering resistance and very friable. England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea be deposited by sedimentation and if buried this may eventually become sandstone and siltstone, (sedimentary rocks). A County town is usually the location of administrative or judicial functions within the county, or it has been established over time as the "de facto" main town of a county. The concept of a county town eventually became detached from its original meaning of where the county administration or county hall is based. In fact, many county towns are no longer part of the administrative county. For example, Nottingham is administered by a unitary authority entirely separate from the rest of Nottinghamshire. Many county towns are classified as cities, but all are referred to as county towns regardless of whether city status is held or not. East Sussex is a county in South East England. It is bordered by the counties of Kent to the north and east, Surrey to the north west and West Sussex to the west, and to the south by the English Channel. Bromley is a large suburban town, the administrative headquarters of the London Borough of Bromley in Greater London, England, United Kingdom. It was historically a market town chartered since 1158 and an ancient parish in the county of Kent. Its location on a coaching route and the opening of a railway station in 1858 were key to its development, and the economic history of Bromley is underpinned by a shift from an agrarian village to commerce and retail. As part of the suburban growth of London in the 20th century, Bromley significantly increased in population and was incorporated as a municipal borough in 1903. It has developed into one of a handful of regionally significant commercial and retail districts outside central London and has formed part of Greater London since 1965. Most of Bromley including the town centre falls under the BR1 postcode district, whereas areas to the west towards Shortlands are part of BR2 instead. Farnham is a town in Surrey, England, within the Borough of Waverley. The town is WSW of London in the extreme west of Surrey, adjacent to the border with Hampshire. By road Guildford is 11 miles (17 km) to the east and Winchester a further 28 miles (45 km) along the same axis as London. Farnham is the largest town in Waverley, and one of the five largest conurbations in Surrey. It is of historic interest, with many old buildings, including a number of Georgian houses. Farnham Castle overlooks the town. A short distance southeast of the town centre are the ruins of Waverley Abbey, Moor Park House and Mother Ludlam's Cave. Farnham is twinned with Andernach in Germany. It is drained by the River Wey (North Branch) which is navigable only to canoes at this point. The North Downs Way National Trail is a long-distance path in southern England, opened in 1978. It runs from Farnham to Dover, past Guildford, Dorking, Merstham, Otford and Rochester, along the Surrey Hills Area of Outstanding Natural Beauty (AONB) and Kent Downs AONB. Maidstone is the county town of Kent, England, south-east of London. The River Medway runs through the centre of the town, linking it with Rochester and the Thames Estuary. Historically, the river was a source and route for much of the town's trade as the centre of the agricultural county of Kent, known as the Garden of England. There is evidence of a settlement in the area dating back to before the Stone Age. London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. Surrey is a county in the south east of England and also one of the home counties bordering Greater London. Surrey shares borders with Kent to the east, East Sussex to the south-east, West Sussex to the south, Hampshire to the west and south-west and Berkshire to the north-west. The county town is Guildford. Surrey County Council sits extraterritorially at Kingston upon Thames, administered as part of Greater London since 1965. With a resident population of 1.1 million, Surrey is the most densely populated and third most populated county in the South East region, after Kent and Hampshire. Seal is a village and civil parish in the Sevenoaks district of Kent , England . The parish is located in the valley between the North Downs and the Greensand ridge to the north - east of the town of Sevenoaks . The village , on the A25 road , although ancient , is fast becoming part of the built - up area of Sevenoaks . In early documents the name of the village is often given as ' Sele ' , ' Sale ' , ' Zela ' or ' La Sela ' . Until recently it was supposed to come from the French word ' salle ' meaning a hall but there is no evidence to support this . The etymology of place names suggests that the name of the village could have come from the Anglo - Saxon word ' sole ' or ' sol ' meaning a ' muddy slough , wallowing place ' or a ' muddy pond that overflows ' . Seal still has a pond at the fork at the bottom of Park Lane which tends to overflow at the present day . Another possibility is Anglo - Saxon sale = `` group of sallow trees '' . ' Seal : The History of a Parish ' by Jean Fox , David Williams and Peter Mountfield , published by Philimores in 2007 , gives comprehensive coverage of the village 's history . Seal 's church , the oldest parts of which date from the 13th Century , is dedicated to St Peter and St Paul and is a grade I listed building . The ecclesiastical parish only became separate from Kemsing in 1874 , although there may well have been a Saxon church on the site of the present building . Visitors to the church , which is normally open during the day , can pick up a free guide leaflet pointing out features of interest . There are more details on the church website , and a page for family historians with some records of burials and baptisms at the church ( not complete ) and information about where to find others . Seal was recorded in the Domesday Book in 1086 The Thames Estuary is the estuary in which the River Thames meets the waters of the North Sea, in the south-east of Great Britain.
