"strait lies between two land masses and connects two larger bodies of water, an isthmus lies between two bodies of water and connects two larger land masses. Some straits have the potential to generate significant tidal power using tidal stream turbines. Tides are more predictable than wave power or wind power. The Pentland Firth (a strait) may be capable of generating 10 GW. Cook Strait in New Zealand may be capable of generating 5.6 GW even though the total energy available in the flow is 15 GW. Straits used for international navigation through the territorial sea between one part of"
"Isthmus An isthmus ( or ; plural: isthmuses; from ) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Canals are often built across isthmuses, where they may be a particularly advantageous shortcut for marine transport. For example, the Panama Canal crosses the Isthmus of Panama, connecting the North Atlantic and Pacific Oceans; the Suez Canal connects the Mediterranean Sea and the Red Sea, cutting across"
"Strip is the name given to a small, twelve-mile-wide strip of land bordering North Carolina, South Carolina, and Georgia in what is currently Transylvania County, North Carolina. This piece of land was given the name because none of its bordering states accepted to govern it, and for a period of time it was considered no-man's land. South Carolina initially governed the land, but it was ceded to the federal government after the American Revolution, in 1787. In turn, the federal government gave the land to the Cherokee of the area, who gave it back to the federal government in 1798."
"land masses and the bridges connecting them. In modern terms, one replaces each land mass with an abstract ""vertex"" or node, and each bridge with an abstract connection, an ""edge"", which only serves to record which pair of vertices (land masses) is connected by that bridge. The resulting mathematical structure is called a graph. Since only the connection information is relevant, the shape of pictorial representations of a graph may be distorted in any way, without changing the graph itself. Only the existence (or absence) of an edge between each pair of nodes is significant. For example, it does not"
"Gap (landform) A gap is a land form that is a low point or opening between hills or mountains or in a ridge or mountain range. It may be called a col, notch, pass, saddle, water gap, or wind gap, and geomorphologically are most often carved by water erosion from a freshet, stream or a river. Gaps created by freshets are often, if not normally, devoid of water through much of the year, their streams being dependent upon the meltwaters of a snow pack. Gaps sourced by small springs will generally have a small stream excepting perhaps during the most"
"is usually used in biogeology to describe land connections that used to exist between continents at various times and were important for migration of people, and various species of animals and plants, e.g. Bering Land Bridge. An isthmus is a land connection between two bigger landmasses, while a peninsula is rather a land protrusion which is connected to a bigger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g. the Panama Canal), and thus resemble two peninsulas; however, canals are artificial features distinguished from"
"Strait A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. Most commonly it is a channel of water that lies between two land masses. Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago. The terms ""channel"", ""pass"" or ""passage"", can be synonymous and used interchangeably with ""strait"", although each is sometimes differentiated with varying senses. In Scotland ""firth"" or ""kyle"" are also sometimes used as synonyms for strait. Many straits are economically important. Straits can be important shipping routes and wars"

The boundaries are mostly unmarked, although where several strips have been amalgamated a deep furrow is sometimes used to divide them. The ancient village game of Haxey Hood is played in this open landscape. A similar system to open fields survives in the United Kingdom as ""allotment gardens"". In many towns and cities there are areas of land of one or two acres (up to about one hectare) interspersed between the buildings. These areas are usually owned by local authorities, or by allotment associations. Small patches"
"the heart of the settlement was extended on the other side of the river or stream, the strips of land belonging to the farms would face one another on either side of the village street. If the elongated arable fields behind a single- or two-row village had a width of less than about 10 metres (which often used to happen as a result of inheritance division), they are known in the Upper German language area as ""Streifenparzellen"" (""strip plots"") or ""Riemenparzellen"" (""belt plots""). Through combining plots and land amelioration more economically viable plots of land could be formed. Relatively elongated"
"Rural–urban fringe The rural–urban fringe, also known as the outskirts, rurban, peri-urban or the urban hinterland, can be described as the ""landscape interface between town and country"", or also as the transition zone where urban and rural uses mix and often clash. Alternatively, it can be viewed as a landscape type in its own right, one forged from an interaction of urban and rural land uses. Its definition shifts depending on the global location, but typically in Europe, where urban areas are intensively managed to prevent urban sprawl and protect agricultural land, the urban fringe will be characterised by certain"
"Land bridge A land bridge, in biogeography, is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonise new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age. In the 19th century a number of scientists noted puzzling geological and zoological similarities between widely separated areas. To solve these problems, ""whenever"

"Riparian zone A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the fifteen terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions the terms riparian woodland, riparian"

Generalized tracks suggest the pre-existence of ancestral biotas, which subsequently become fragmented by tectonic and/or climate change. The area where two or more generalized tracks intersect is called ""node"". It means that different ancestral biotic and geological fragments interrelate in space/time, as a consequence of terrain collision, docking, or suturing, thus constituting a composite area. A concentration of numerical, genetical or morphological diversity within a taxon in a given area constitutes a ""main massing"". Over the"

"Valley A valley is a low area between hills or mountains often with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, at least with respect to the cross section of the slopes or hillsides. A valley in its broadest geographic sense is also known as a ""dale"". Other terms used for valleys are: Similar geological structures,"

The area of land that separates the two bodies of water by only a few miles became known as ""Between the Rivers"" since at least the 1830s or 1840s. After the Cumberland River was impounded in the 1960s and a canal was constructed between the two lakes, Land Between the Lakes became the largest inland peninsula in the United States. Downstream from this area, the courses of the two rivers diverge again, with the mouth of the Cumberland"

Usually ""escarpment"" is used interchangeably with scarp. Some sources differentiate the two terms, however, where ""escarpment"" refers to the margin between two landforms, while ""scarp"" is synonymous with a cliff or steep slope. The surface of the steep slope is called a scarp face. This (escarpment) is a ridge which has a gentle (dip) slope on one side and a steep (scarp) slope on the other side.

They are often occupied and shaped by a subsequent stream. The term is frequently used if a mountain range also has prominent transverse valleys, where rivers cut through the mountain chains in so-called water gaps. Many longitudinal valleys follow the strike of the rock strata or significant geological fault lines. These are formed in conjunction with the tectonic movements during the mountain building, which in turn are"

Hedges used to separate a road from adjoining fields or one field from another, and of sufficient age to incorporate larger trees, are known as hedgerows. Often they serve as windbreaks to improve conditions for the adjacent crops, as in bocage country. When clipped and maintained, hedges are also a simple form of topiary. The development of hedges over the centuries is preserved in their"

"Isthmus of Corinth The Isthmus of Corinth is the narrow land bridge which connects the Peloponnese peninsula with the rest of the mainland of Greece, near the city of Corinth. The word ""isthmus"" comes from the Ancient Greek word for ""neck"" and refers to the narrowness of the land. The Isthmus was known in the ancient world as the landmark separating the Peloponnese from mainland Greece. In the first century AD the geographer Strabo noted a stele on the Isthmus of Corinth, which bore two inscriptions. One towards the East, i.e. towards Megara, reading: """"Here is not Peloponnesus, but Ionia"""""
