StraitA strait is a water body connecting two seas or water basins. The surface water is, for the most part, at the same elevation on both sides and can flow through the strait in either direction, although the topography generally constricts the flow somewhat. In some straits, there is a dominant directional current. Most commonly, the strait is a narrow channel that lies between two land masses.
River deltaA river delta is a landform, typically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the river mouth, where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river.
Body of waterA body of water is a significant accumulation of water on the surface of the earth. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where accumulated water moves from one place to another are also considered bodies of water.
ErosionErosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.
RiverA river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth.CanalThe Alter Strom, in the sea resort of Warnemünde, GermanyThe Royal Canal in IrelandSmall boat canals such as the Basingstoke Canal fuelled the Industrial Revolution in much of Europe and the United States.Bridge on the Naviglio Grande, in the town of Cassinetta di Lugagnano, in ItalyCanal in Broek in Waterland, NetherlandsCanal in VeniceCanals or artificial waterways are waterways or engineeredchannels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transportvehicles (e.g. water taxi).
NavigabilityA body of water, such as a canal, lake, reservoirs, or river, is navigable if it is calm, deep, and wide enough for a watercraft (e.g. boats) to pass safely. Navigability is also referred to in the broader context of a body of water having sufficient under keel clearance for a vessel. Such a navigable water is called a waterway, and is preferably with few obstructions against direct traverse that need avoiding, such as rocks, reefs or trees.
PortA port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals.
LandformA 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.
Physical geographyPhysical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere.
HydrologyHydrology (from Ancient Greek (húdōr)'water' and (-logía)'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and drainage basin sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography.CognateIn historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate.*As an Amazon Associate I earn from qualifying purchases.
