The mountain range is home to the White Tank Mountain Regional Park The White Tank Mountain Regional Park is a large regional park located in west-central Maricopa County, Arizona. Encompassing of desert and mountain landscape, it is the largest regional park in the county. The bulk of the White Tank Mountain ... and is a regional recreation hub. The range, often referred to simply as the White Tanks, is a moderate-sized mountain range whose peaks rise to an elevation around . The range consists of a series of numerous ridges and canyons, and as such, lacks a single, prominent peak. The highest point in the range, at an elevation of , is Barry Goldwater Peak. The mountain range was formed through tectonic activities as part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arizona
Arizona ( ; nv, Hoozdo Hahoodzo ; ood, Alĭ ṣonak ) is a state in the Southwestern United States. It is the 6th largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest. Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase. Southern Arizona is known for its desert cl ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenix Metropolitan Area
The Phoenix Metropolitan Area – also the Valley of the Sun, the Salt River Valley, or Metro Phoenix (known by most locals simply as “the Valley”) – is the largest metropolitan area in the Southwestern United States, centered on the city of Phoenix, that includes much of the central part of Arizona. The United States Office of Management and Budget designates the area as the Phoenix-Mesa-Chandler Metropolitan Statistical Area (MSA), defining it as Maricopa and Pinal counties. As of the 2020 census, Metro Phoenix had 4,845,832 residents, making it the 11th largest metropolitan area in the nation by population. It anchors the Arizona Sun Corridor megaregion along with the second most populous metropolitan area in the state, the Tucson metropolitan area. The gross domestic product of the Phoenix Metropolitan Area was $255 billion in 2018, 16th largest amongst metro areas in the United States.

Buckeye, Arizona
Buckeye is a city in Maricopa County, Arizona, United States, and is the westernmost suburb in the Phoenix metropolitan area. As of the 2020 census the population was 91,502, up from 50,876 in 2010 and 6,537 in 2000. It was the fastest-growing city in the United States for both 2017 and 2018. History In 1877, Thomas Newt Clanton led a group of six men, three women, and ten children from Creston, Iowa, to Arizona, where they settled in the Buckeye area. Early settler Malie M. Jackson developed of the Buckeye Canal from 1884 to 1886, which he named after his home state of Ohio's moniker, "The Buckeye State". The town was founded in 1888 and originally named " Sidney", after Jackson's hometown in Ohio. However, because of the significance of the canal, the town became known as Buckeye. The name was legally changed to Buckeye in 1910. The town was incorporated in 1929, at which time it included . The town's first mayor was Hugh M. Watson (1956–1958), who founded the Buckeye V ...

Surprise, Arizona
Surprise is a city in Maricopa County, in the U.S. state of Arizona. The population was 143,148 at the 2020 census, up from 117,517 in 2010 and just 30,848 in 2000. The city has a Aquatics Center and Maricopa County's northwest regional library, a $5.5 million, library, along with a 100.3 cost of living index. History The city was founded in 1938 by Flora Mae Statler, who named it Surprise as she "would be surprised if the town ever amounted to much." Surprise officials previously thought the city was founded by Statler's husband, real estate developer and state legislator Homer C. Ludden, but in 2010 property records were discovered which listed Statler owning the land before she met Ludden. When Surprise was subdivided to build inexpensive houses for agricultural workers, there were only a few houses and a gas station on the one-square-mile (1.6 km) parcel of land. Since then, the town has experienced tremendous growth. It incorporated as a city in 1960. The townsite ... [...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 ...

Detachment Fault
A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics. Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic footwalls that are called metamorphic core complexes. They are thought to have formed as either initially low-angle structures or by the rotation of initially high-angle normal faults modified also by the isostatic effects of tectonic denudation. They may also be called denudation faults. Examples of detachment faulting include: *The Snake Range detachment system of the Basin and Range Province of western North America which was active during the Miocene *The Nordfjord-Sogn detachment of western Norway active during the Devonian Period *The Whipple detachment in southeastern California Detachment faults have been found on the sea floor close to divergent plate boundaries characterised by a limited supply of upwelling magma, su ...

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...
