Cultural diversity – regions are a way to understand human diversity. [1] Uniform regions and formal regions share a similar definition, with formal regions being “a group of places that have similar conditions". [4] Even in formal regions, it is true that no region is completely homogeneous, as characteristics vary from place to place. [4]
Early examples of what would lead to more formal technical drawing practices included the drawings and geometric calculations used to construct aqueducts, bridges, and fortresses. Technical drawings also figured in the 12th-century design of cathedrals and castles, albeit such drawings were more typically produced by artisans and stonemasons ...
A map graph is a graph formed from a set of finitely many simply-connected interior-disjoint regions in the plane by connecting two regions when they share at least one boundary point. When at most three regions meet at a point, the result is a planar graph, but when four or more regions meet at a point, the result can be nonplanar (for example ...
Physiographic regions are a means of defining Earth's landforms into independently distinct, mutually exclusive areas, independent of political boundaries. It is based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces , and physiographic sections.
They are used at a variety of scales, from large-scale engineering drawings and architectural plans, through topographic maps and bathymetric charts, up to continental-scale maps. "Contour line" is the most common usage in cartography , but isobath for underwater depths on bathymetric maps and isohypse for elevations are also used.
A tourism region is a geographical region that has been designated by a governmental organization or tourism bureau as having common cultural or environmental characteristics. These regions are often named after a geographical, former, or current administrative region or may have a name created for tourism purposes. The names often evoke ...
The newer formations are the drumlins and glacial valleys as a result of the last ice age, and the sinkholes and cave formations in the limestone regions of Clare. [7] [8] Ireland's geological history includes a wide range of elements, from volcanism and tropical seas to the last glacial period. Ireland was formed in two distinct parts, which ...
