Cliffs Of Dover
The White Cliffs of Dover are the region of English coastline facing the Strait of Dover and France. The cliff face, which reaches a height of , owes its striking appearance to its composition of chalk accented by streaks of black flint, deposited during the Late Cretaceous. The cliffs, on both sides of the town of Dover in Kent, stretch for . The White Cliffs of Dover form part of the North Downs. A section of coastline encompassing the cliffs was purchased by the National Trust in 2016. The cliffs are part of the Dover to Kingsdown Cliffs Site of Special Scientific Interest and Special Area of Conservation. The point where Great Britain is closest to continental Europe, on a clear day the cliffs are visible from France, approximately away. A celebrated UK landmark, the cliffs have featured on commemorative postage stamps issued by the Royal Mail, including in their British coastline series in 2002 and UK A-Z series in 2012.

Sea Cliff
A cliffed coast, also called an abrasion coast, is a form of coast where the action of marine waves has formed steep cliffs that may or may not be precipitous. It contrasts with a flat or alluvial coast. Formation In coastal areas in which the land surface dips at a relatively steep angle below the water table, the continuous action of marine waves on the coastline, known as abrasion, may create a steep declivity known as a cliff, the slope angle of which depends on a variety of factors including the jointing, bedding and hardness of the materials making up the cliff as well as the erosional processes themselves.Herbert Louis and Klaus Fischer: ''Allgemeine Geomorphologie'', de Gruyter, 4th ed., Berlin 1979, pp. 532-537 The slope is constantly being eroded. The waves attacking the cliff-foot form a wave-cut notch by constant abrasion action producing an overhang. This overhang grows in size as the cliff is undercut, until it collapses under its own weight. The loose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chalk Group
The Chalk Group (often just called the Chalk) is the lithostratigraphic unit (a certain number of rock strata) which contains the Upper Cretaceous limestone succession in southern and eastern England. The same or similar rock sequences occur across the wider northwest European chalk 'province'. It is characterised by thick deposits of chalk, a soft porous white limestone, deposited in a marine environment. Chalk is a limestone that consists of coccolith biomicrite. A biomicrite is a limestone composed of fossil debris ("bio") and calcium carbonate mud (" micrite"). Most of the fossil debris in chalk consists of the microscopic plates, which are called coccoliths, of microscopic green algae known as coccolithophores. In addition to the coccoliths, the fossil debris includes a variable, but minor, percentage of the fragments of foraminifera, ostracods and mollusks. The coccolithophores lived in the upper part of the water column. When they died, the microscopic calcium carbonat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratigraphy
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of strata or rock layering and the importance of fossil markers for correlating strata; he created the first geo ...

YouTube
YouTube is an American social media and online video sharing platform owned by Google. YouTube was founded on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim who were three former employees of PayPal. Headquartered in San Bruno, California, it is the second-most-visited website in the world, after Google Search. In January 2024, YouTube had more than 2.7billion monthly active users, who collectively watched more than one billion hours of videos every day. , videos were being uploaded to the platform at a rate of more than 500 hours of content per minute, and , there were approximately 14.8billion videos in total. On November 13, 2006, YouTube was purchased by Google for $1.65 billion (equivalent to $ billion in ). Google expanded YouTube's business model of generating revenue from advertisements alone, to offering paid content such as movies and exclusive content produced by and for YouTube.

Coccolith
Coccoliths are individual plates or scales of calcium carbonate formed by coccolithophores (single-celled phytoplankton such as ''Emiliania huxleyi'') and cover the cell surface arranged in the form of a spherical shell, called a '' coccosphere''. Overview Coccoliths, which are about 2-25 micrometres across, enclose coccolithophores, which are spherical cells about 5-100 micrometres across. Coccolithophores are an important group of about 200 marine phytoplankton species which cover themselves with a calcium carbonate shell called a "coccosphere". They are ecologically and biogeochemically important but the reason why they calcify remains elusive. One key function may be that the coccosphere offers protection against microzooplankton predation, which is one of the main causes of phytoplankton death in the ocean.

Van Heyningen And Haward Architects
van Heyningen and Haward is an architectural practice, founded in 1983 by Birkin Haward and Joanna van Heyningen, and now owned and managed by James McCosh and Meryl Townley. The London architects work primarily in education, and have also worked in the heritage, community and health sectors. In 2010 the practice produced a monograph detailing their work to date; ''van Heyningen and Haward – Buildings and Projects''. The book was published by Right Angle Publishing and edited by Ian Latham. As well as giving an overview of the projects undertaken by the practice from inception until publication, it also includes essays by Trevor Garnham and contributions by Ken Powell and Patrick Lynch. The launch party for the book was held at Latymer Upper School, a long-standing client of the practice.

Area Of Outstanding Natural Beauty
An Area of Outstanding Natural Beauty (AONB; , AHNE) is one of 46 areas of countryside in England, Wales, or Northern Ireland that has been designated for conservation due to its significant landscape value. Since 2023, the areas in England and Wales have also adopted the name National Landscape (). Areas are designated in recognition of their national importance by the relevant public body: Natural England, Natural Resources Wales, and the Northern Ireland Environment Agency respectively. On 22 November 2023, following a review, the AONBs in England and Wales adopted the National Landscapes name, and are in the process of rebranding. AONBs in Northern Ireland did not rename. The name "area of outstanding natural beauty" is still the designated legal term. In place of the term AONB, Scotland uses the similar national scenic area (NSA) designation. Areas of Outstanding Natural Beauty enjoy levels of protection from development similar to those of UK national parks, but unli ...

Kent Downs
The Kent Downs is an Area of Outstanding Natural Beauty (AONB) in Kent, England. They are the eastern half of the North Downs and stretch from the London/Surrey borders to the White Cliffs of Dover, including a small section of the London Borough of Bromley. The AONB also includes the Greensand Ridge, a prominent sandstone escarpment which lies south of the chalk escarpment of the North Downs. It was first designated as an AONB in July 1968 and covers 878 square km (326 square miles). The AONB's highest point is Toy's Hill, at 250m above sea level, and its boundaries include three main rivers: the Darent, Medway and Stour. To the west, Surrey Hills AONB adjoins the Kent Downs AONB, and includes a continuation of the North Downs chalk ridge which runs through the Kent Downs, stretching from Farnham to the English Channel and reappearing within the Parc Naturel Régional des Caps et Marais d’Opale in France. High Weald AONB lies to the south east, separated by a distance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
