Trap Mountain
Trap Mountain is a summit in Brewster County, Texas, United States. Description Trap Mountain is part of the Chisos Mountains where it is set in the Chihuahuan Desert and Big Bend National Park. The mountain is composed chiefly of Burro Mesa Rhyolite (volcanic rock) which formed 29 million years ago during the Oligocene period. Based on the Köppen climate classification, the mountain is located in a hot arid climate zone with hot summers and mild winters. This climate supports plants on the slopes such as creosote bush, ocotillo, lechuguilla and yucca. Any scant precipitation runoff from the peak's slopes drains to the Rio Grande which is six miles to the southwest. Topographic relief is significant as the summit rises above Ross Maxwell Scenic Drive in one-half mile (0.8 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names, and has been listed in publications since at least 1914.

Fouquieria Splendens
''Fouquieria splendens'', commonly known as ocotillo, is a plant indigenous to the Mojave Desert, Mojave, Sonoran Desert, Sonoran, Chihuahuan Desert, Chihuahuan and Colorado Desert, Colorado deserts in the Southwestern United States (southern California, southern Nevada, Arizona, New Mexico, Texas), and northern Mexico (as far south as Hidalgo (state), Hidalgo and Guerrero). Ocotilos look dessicated on the outside, but they are semi-Succulent plant, succulent; it is more closely related to the tea plant and blueberry, blueberries than to cactuses. It regenerates leaves after rainfall. They can be planted as garden ornamental plant, ornamentals. Names The name ''ocotillo'' comes from the Nahuatl word ''ocotl'' meaning "torch". It is also known as buggywhip, coachwhip, candlewood, slimwood, desert coral, Jacob's staff, Jacob cactus, and vine cactus. Botany It grows in dry, generally rocky desert soils. An ocotillo plant reaches maturity at 60–100 years, it grows to a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Texas
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Geography Of Texas
The geography of Texas is diverse and large. Occupying about 7% of the total water and land area of the U.S., it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico. Texas is in the South Central United States of America, and is considered to form part of the U.S. South and also part of the U.S. Southwest. By residents, the state is generally divided into North Texas, East Texas, Central Texas, South Texas, West Texas and, sometimes, the Panhandle and Upper Gulf Coast, but according to the '' Texas Almanac'', Texas has four major physical regions: Gulf Coastal Plains, Interior Lowlands, Great Plains, and Basin and Range Province. This has been cited as the difference between human geography and physical geography, although the fact that Texas was granted the prerogative to divide into as many as five U.S. states may be a historical motive for Texans definin ...

Igneous Rock
Igneous rock ( ), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top of the Earth's crust by volume. Igneous rock ...

Trap Rock
Trap rock, also known as either trapp or trap, is any dark-colored, fine-grained, non-granitic intrusive or extrusive igneous rock. Types of trap rock include basalt, peridotite, diabase, and gabbro.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, J.A., eds. (2005) ''Glossary of Geology'' (5th ed.) American Geological Institute, Alexandria, Virginia. 779 pp. Trap is also used to refer to flood (plateau) basalts, such as the Deccan Traps and Siberian Traps.Le Maitre, R. W., ed. (2002) ''Igneous Rocks: A Classification and Glossary of Terminology''. Cambridge University Press, New York. 236 pp. The erosion of trap rock created by the stacking of successive lava flows often creates a distinct stairstep landscape from which the term ''trap'' was derived from the Swedish word , which means "stairs". The slow cooling of magma either as a sill or as a thick lava flow sometimes creates systematic vertical fractures within the resulting layer of trap rock. These fractures of ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a Federal government of the United States, federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geography, geographic names throughout the federal government of the United States. History Following the American Civil War, more and more American pioneer, American settlers began moving westward, prompting the Federal government of the United States, U.S. federal government to pursue some sort of consistency for referencing landmarks on maps and in official documents. As such, on January 8, 1890, Thomas Corwin Mendenhall, superintendent of the United States Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography."

Topographic Relief
Terrain (), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drainage characteristics, drainage systems, groundwater systems, water ...
