Carlsbad Caverns
Carlsbad Caverns National Park is an American national park in the Guadalupe Mountains of southeastern New Mexico. The primary attraction of the park is the show cave Carlsbad Cavern. Visitors to the cave can hike in on their own via the natural entrance or take an elevator from the visitor center. The park entrance is located on US Highway 62/180, approximately southwest of Carlsbad, New Mexico. Carlsbad Caverns National Park participates in the Junior Ranger Program. The park has two entries on the National Register of Historic Places: The Caverns Historic District and the Rattlesnake Springs Historic District. Approximately two-thirds of the park has been set aside as a wilderness area, helping to ensure no future changes will be made to the habitat. Carlsbad Cavern includes a large limestone chamber, named simply the Big Room, which is almost long, wide, and high at its highest point. The Big Room is the largest chamber in North America and the 31st largest in the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eddy County, New Mexico
Eddy County is a county located in the U.S. state of New Mexico. As of the 2010 census, the population was 53,829. Its county seat and largest city is Carlsbad. The county was created in 1891 and later organized in 1892. It is north of the Texas state line. Eddy County comprises the Carlsbad- Artesia, NM Micropolitan Statistical Area. Carlsbad Caverns National Park is located in this county. Eddy County is the location of the Waste Isolation Pilot Plant. History In 1866, Charles Goodnight and Oliver Loving drove vast herds of cattle along the Pecos and set up "cow camps" in Seven Rivers and what is now Carlsbad. John Chisum soon joined them and brought an estimated 100,000 head of cattle of his own through the Pecos Valley. In 1881, Charles B. Eddy came to the area, and with his brother, John, and partner Amos Bissell, developed the Eddy-Bissell Cattle Company. In 1884, the Eddy brothers and Bissell broke ground on the Halagueno Ranch which encompassed an area from Seven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diorama At The Carlsbad Cavern Visitor's Center
A diorama is a replica of a scene, typically a three-dimensional full-size or miniature model, sometimes enclosed in a glass showcase for a museum. Dioramas are often built by hobbyists as part of related hobbies such as military vehicle modeling, miniature figure modeling, or aircraft modeling. In the United States around 1950 and onward, natural history dioramas in museums became less fashionable, leading to many being removed, dismantled or destroyed. Etymology The word "diorama" originated in 1823 as a type of picture-viewing device, from the French in 1822. The word literally means "through that which is seen", from the Greek di- "through" + orama "that which is seen, a sight". The diorama was invented by Louis Daguerre and Charles Marie Bouton, first exhibited in Paris in July 1822 and at The Diorama, Regent's Park on September 29, 1823. The meaning "small-scale replica of a scene, etc." is from 1902. Daguerre's and Bouton's diorama consisted of a piece of materi ...

Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid ( Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula . It is a colorless, odorless and viscous liquid that is miscible with water. Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid, but to the contrary dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus the reverse procedure of adding water to the acid should not be performed since the heat released may boi ...

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...

Mid-Continent Oil Field
The Mid-continent oil field is a broad area containing hundreds of oil fields in Arkansas, Kansas, Louisiana, New Mexico, Oklahoma and Texas. The area, which consists of various geological strata and diverse trap types, was discovered and exploited during the first half of the 20th century. Most of the crude oil found in the onshore Mid-continent oil field is considered to be of the mixed base or intermediate type (a mix of paraffin base and asphalt base crude oil types). History The first commercially successful oil well drilled in the area was the Norman No. 1 near Neodesha, Kansas, on November 28, 1892. The successes that followed of the Nellie Johnstone No. 1 at Bartlesville, Oklahoma in 1897, Spindletop at Beaumont, Texas in 1901, and the Ida Glenn No. 1 at Glenn Pool, Oklahoma in 1905, demonstrated the existence of a large oil field in the central and southwestern United States. It became known as the Mid-continent oil field. Continued drilling found many other oil field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Fossils In Carlsbad Cavern
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tectonic
Tectonics (; ) are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles is essential to geomorphologists to explain erosion patterns and other Earth surface features. Main types of tectonic regime Extensional tectonics Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere. This type of tectonics is found ...

Evaporite
An evaporite () is a water-soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments. Formation of evaporite rocks Although all water bodies on the surface and in aquifers contain dissolved salts, the water must evaporate into the atmosphere for the minerals to precipitate. For this to happen, the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small basin fed by a limited input of water. When evaporation occurs, the remaining water is enriched in salts, and they precipitate when the water becomes supersaturated. Evaporite depositi ...
