Vršič Pass
The Vršič Pass (; sl, prelaz Vršič, it, passo della Moistrocca, german: Werschetzpass), with an elevation of , is a high mountain pass across the Julian Alps in northwestern Slovenia. It is the highest pass in Slovenia, as well as the highest in the Eastern Julian Alps. It connects Upper Carniola with the Trenta Valley in the Slovene Littoral. The road across the pass, now known as Russian Road (), was originally built for military purposes in the early 19th century and followed an earlier trade route. The Vršič Pass is considered an excellent starting point for excursions to surrounding peaks. Name The Slovene common noun literally means 'little peak', a diminutive form of the word 'peak'. The name originally referred to Mount Vršič (), located about east of the Vršič Pass. The name was not applied to the pass until 1911. The name of the peak was first attested in written sources as ''Werschez'' in 1763–87. Locally, the pass is known as (first attested in 1763 ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, 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 in the late 19th century, which entered German much earlier ...

A View Of Copacabana Beach And Matt's Sump At The Bottom Of Renejevo Brezno (Renee's Abyss) At Mt
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguis ...

Chevé Cave
Chevé Cave ( ; es, Cueva Chevé, Sistema Chevé) is a deep cave located in the Sierra Juárez mountain range in the southern Mexico state of Oaxaca. As of 2021, its deepest point has been measured at deep, making it the second deepest known cavern in Mexico and the Americas, as well as the world’s 11th deepest cave. The main cave apparently ends in a terminal sump. , the present limit of exploration in Chevé, at 11.77 kilometers from the nearest entrance, represents one of the most remote locations ever attained inside any cave on Earth. The logistics of reaching this point are enormous: more than two kilometers of rope need to be rigged and seven underground camps established. Chevé is the deepest proven freshwater hydrological system in the world. Temperatures in Chevé are moderate, ranging from . It has been most thoroughly explored under the leadership of caver Bill Stone. Exploration history Chevé Cave was discovered in the mid-1980s by Bill Farr and Carol Vesely ...

Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes co ...

Hydrogeology
Hydrogeology (''hydro-'' meaning water, and ''-geology'' meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers). The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably. Hydrogeology is the study of the laws governing the movement of subterranean water, the mechanical, chemical, and thermal interaction of this water with the porous solid, and the transport of energy, chemical constituents, and particulate matter by flow (Domenico and Schwartz, 1998). Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. The main concerns in groundwater engineering include groundwater contamination, conservation of supplies, and water quality.Walton, William C. (November 1990). ''Principles of Groundwater Engin ...

Speleologist
Speleology is the scientific study of caves and other karst features, as well as their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking''. Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont wrote detailed descriptions of some Mendip caves in the 1680s. The term speleology was coined by Émile Rivière in 1890. Prior to the mid-nineteenth century the scientific valu ...
