Topography in the context of "Strait"

A coast (also called the coastline, shoreline, or seashore) is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, such as that caused by waves. The geological composition of rock and soil dictates the type of shore that is created. Earth has about 620,000 km (390,000 mi) of coastline.

Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor ecosystems, such as freshwater or estuarine wetlands, that are important for birds and other terrestrial animals. In wave-protected areas, coasts harbor salt marshes, mangroves, and seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic animals. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals (e.g. mussels, starfish, barnacles) and various kinds of seaweeds.

Geopolitics (from Ancient Greek γῆ gê 'earth, land' and πολιτική politikḗ 'politics') is the study of the effects of Earth's geography on politics and international relations. Geopolitics usually refers to countries and relations between them. According to multiple researchers, the term is currently being used to describe a broad spectrum of concepts, in a general sense used as "a synonym for international political relations", but more specifically "to imply the global structure of such relations"; this usage builds on an "early-twentieth-century term for a pseudoscience of political geography" and other pseudoscientific theories of historical and geographic determinism.

At the level of international relations, geopolitics is a method of studying foreign policy to understand, explain, and predict international political behavior through geographical variables. These include area studies, climate, topography, demography, natural resources, and applied science of the region being evaluated.

The Angel of the North is a contemporary sculpture by Antony Gormley, located in Gateshead, Tyne and Wear, England. Completed in 1998, it is seen by an estimated 33 million people every year due to its proximity to the A1 and A167 roads and the East Coast Main Line. The design of the Angel, like many of Gormley's works, is based on Gormley's own body. The COR-TEN weathering steel material gives the sculpture its distinctive rusty, oxidised colour. It stands 20 metres (66 ft) tall with a wingspan of 54 metres (177 ft). The vertical ribs on its body and wings act as an external skeleton which direct oncoming wind to the sculpture's foundations, allowing it to withstand wind speeds of over 100 miles per hour (160 km/h).

The sculpture was commissioned and delivered by Gateshead Council who approached Gormley to be the sculptor. Although initially reluctant, Gormley agreed to undertake the project after visiting and being inspired by the Angel's proposed site, a former colliery overlooking the varied topography of the Tyne and Wear Lowlands National Character Area.

Karst (/kɑːrst/) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions.

Subterranean drainage may limit surface water, with few if any rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground.

A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins.

In topography, prominence (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) is the relative height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the parent peak (if any) is some higher mountain, selected according to various criteria.
