:Category:Wild Caves
Wild caves are caves that have few or no provisions which make it easy for the general public to visit. Visiting such caves, if even possible, should not be attempted without extensive preparation. There are often many dangers in wild caves and knowledge, experience and special caving gear are required to mitigate those dangers. Caving {{CatAutoTOC ...

Show Cave
A show cave—also called tourist cave, public cave, and, in the United States, commercial cave—is a cave which has been made accessible to the public for guided visits. Definition A show cave is a cave that has been made accessible to the public for guided visits, where a cave is defined as a natural occurring void beneath the surface of the earth, per the International Show Caves Association. A show cave may be managed by a government or commercial organization and made accessible to the general public, usually for an entrance fee. Unlike wild caves, they may possess regular opening hours, guided group tours, constructed trails and stairs, color artificial illumination and other lighting, musical/video/laser shows and concerts, elevators, small trains, and boats if they contain underground water features. Some caves (mainly in Asia) open to the public have temples, monasteries and religious statues or monuments. Some caves are visited by millions of tourists annually ...

Fort Contrechoeur
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its ' cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, ...

French And Indian Wars
The French and Indian Wars were a series of conflicts that occurred in North America between 1688 and 1763, some of which indirectly were related to the European dynastic wars. The title ''French and Indian War'' in the singular is used in the United States specifically for the warfare of 1754–63, which composed the North American theatre of the Seven Years' War and the aftermath of which led to the American Revolution. The French and Indian Wars were preceded by the Beaver Wars. In Quebec, the various wars are generally referred to as the Intercolonial Wars. Some conflicts involved Spanish and Dutch forces, but all pitted the Kingdom of Great Britain, British America, its colonies, and their Indigenous peoples of the Americas, Indigenous allies on one side against France, French colonization of the Americas, its colonies, and its Indigenous allies on the other. A driving cause behind the wars was the desire of each country to take control of the interior territories of Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudokarst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, 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. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Illusion
Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual perception, percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo illusion, Ponzo, Poggendorff illusion, Poggendorff, an ...

Gravity Hill
A gravity hill, also known as a magnetic hill, mystery hill, mystery spot, gravity road, or anti-gravity hill, is a place where the layout of the surrounding land produces an optical illusion, making a slight downhill slope appear to be an uphill slope. Thus, a car left out of gear will appear to be rolling uphill against gravity. Hundreds of gravity hills are recognized worldwide. The slope of gravity hills is an optical illusion, although sites are often accompanied by claims that magnetic or supernatural forces are at work. The most important factor contributing to the illusion is a completely or mostly obstructed horizon. Without a horizon, it becomes difficult for a person to judge the slope of a surface, as a reliable reference is missing. Objects which one would normally assume to be more or less perpendicular to the ground, such as trees, may be leaning, offsetting the visual reference. A 2003 study looked into how the absence of a horizon can skew the perspective on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
