Atl Fault
The Atl Fault is a right lateral-moving transform fault located on the seafloor of the southern Gulf of California. It links the Farallon Basin to the north with the Pescadero Basin to the south. All these features are part of the Gulf of California Rift Zone, the northern extension of the East Pacific Rise. The name derives from the Nahuatl Nahuatl (; ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about Nahua peoples, most of whom live mainly in Central Mexico and have smaller ... word meaning "water".

Transform Fault
A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. A transform fault is a special case of a ''strike-slip fault'' that also forms a plate boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. Nomenclature Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth's surface. Background Geophysicist ...

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

Farallon Basin
The Farallon Basin is a submarine depression located on the seabed at the southern end of the Gulf of California. The basin results from the activity of one of the several spreading centers in the Gulf. The basin is linked to the Atl Fault to the south, and the Farallon Fault in the north. The Farallon Basin has a spreading axis at its center, so the seafloor here is oceanic crust, transitioning into thin, rifted continental crust at the basin's edges. Spreading centers in the Gulf, like this one in Farallon, are different from more well known spreading axes like the Mid-Atlantic Ridge and East Pacific Rise, since they form as deep rift valleys rather than bathymetric highs. One familiar source of terrigenous input to the Gulf is the Colorado River, which empties into the northern Gulf (though no longer consistently, as a result of overuse for irrigation). Further south, especially in the eastern Gulf, the Sierra Madre Occidental The Sierra Madre Occidental is a major mount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pescadero Basin
The Pescadero Basin is a submarine depression located on the seabed at the southern end of the Gulf of California off the coast of the Mexican state of Sinaloa. The basin results from the activity of one of the several spreading centers in the Gulf. The basin is linked to the Pescadero Fault to the south, and the Atl Fault in the north, two of the transform faults of the Gulf of California Rift Zone, i. e. the northern extension of the eastern Pacific Ridge. Studies released around 2015 have revealed that the Pescadero Basin is a hydrothermal field rich in particular in carbonate chimneys, the only ones so far discovered in the Pacific Ocean, and thus in the typical living species that inhabit these environments.Dave Clague & Dave CaressMBARI researchers discover deepest known high-temperature hydrothermal vents in Pacific Ocean MBARI (Monterey Bay Aquarium Research Institute The Monterey Bay Aquarium Research Institute (MBARI) is a private, non-profit oceanographic resear ...

Gulf Of California Rift Zone
The Gulf of California Rift Zone (GCRZ) is the northernmost extension of the East Pacific Rise which extends some from the mouth of the Gulf of California to the southern terminus of the San Andreas Fault at the Salton Sink. The GCRZ is an incipient rift zone akin to the Red Sea Rift. In the GCRZ continental crust originally associated with the North American Plate has been pulled apart by tectonic forces and is being replaced by newly formed oceanic crust and seafloor spreading. The rifting has resulted in the transfer of the Baja California Peninsula to the Pacific Plate. List of GCRZ transform faults From north to south: * Imperial Fault Zone * Cerro Prieto Fault * Ballenas Fault * Partida Fault * San Lorenzo Fault * Guaymas Fault * Carmen Fault * Farallon Fault * Atl Fault * Pescadero Fault * Tamayo Fault List of GCRZ rift basins From north to south: * Brawley Seismic Zone * Cerro Prieto * Wagner Basin * Consag Basin * Adair-Tepoca Basin * Tiburon Basin ...

East Pacific Rise
The East Pacific Rise is a mid-ocean rise (termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate. It runs south from the Gulf of California in the Salton Sea basin in Southern California to a point near 55° S, 130° W, where it joins the Pacific-Antarctic Ridge trending west-southwest towards Antarctica, near New Zealand (though in some uses the PAR is regarded as the southern section of the EPR). Much of the rise lies about 3200 km (2000 mi) off the South American coast and rises about 1,800–2,700 m (6,000–9,000 ft) above the surrounding seafloor.

Nahuatl
Nahuatl (; ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about Nahua peoples, most of whom live mainly in Central Mexico and have smaller populations in the United States. Nahuatl has been spoken in central Mexico since at least the seventh century CE. It was the language of the Aztec/ Mexica, who dominated what is now central Mexico during the Late Postclassic period of Mesoamerican history. During the centuries preceding the Spanish and Tlaxcalan conquest of the Aztec Empire, the Aztecs had expanded to incorporate a large part of central Mexico. Their influence caused the variety of Nahuatl spoken by the residents of Tenochtitlan to become a prestige language in Mesoamerica. After the conquest, when Spanish colonists and missionaries introduced the Latin alphabet, Nahuatl also became a literary language. Many chronicles, grammars, works of poetry, administrative docu ...

Geology Of Mexico
The geography of Mexico describes the geographic features of Mexico, a country in the Americas. Mexico is located at about 23° N and 102° W in the southern portion of North America. From its farthest land points, Mexico is a little over in length. Mexico is bounded to the north by the United States (specifically, from west to east, by California, Arizona, New Mexico, and Texas), to the west and south by the Pacific Ocean, to the east by the Gulf of Mexico, and to the southeast by Belize, Guatemala, and the Caribbean Sea. The northernmost constituent of Latin America, it is the most populous Spanish-speaking country in the world. Mexico is the world's 13th largest country, three times the size of Texas. Almost all of Mexico is on the North American Plate, with small parts of the Baja California Peninsula in the northwest on the Pacific and Cocos Plates. Some geographers include the portion east of the Isthmus of Tehuantepec including the Yucatán Peninsula within North Amer ...
