Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Fields
A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or a polygenetic volcanic field. Description Alexander von Humboldt observed in 1823 that geologically young volcanoes are not distributed uniformly across the Earth's surface, but tend to be clustered into specific regions. Young volcanoes are rarely found within cratons, but are characteristic of subduction zones, rift zones, or in ocean basins. Intraplate volcanoes are clustered along hotspot traces. Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. Scoria cones are particularly prone to cluster into volcanic fields, which are typically in diameter and consist of several tens ...

Landforms Of The State Of Mexico
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Mountain Ranges 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 ...

Sierra De Ajusco-Chichinauhtzin
The Sierra del Ajusco-Chichinauhtzin, (Ajusco-Chichinautzin Mountain Range) also known as ''Serranía del Ajusco'' or ''Sierra de Chichinauhtzin'', is a Mexican mountain range located between Mexico City and the states of Morelos and Mexico. It makes up the southern part of the mountain necklace that surrounds Mexico City. It is made up of more than one hundred volcanic cones, among which are: Tláloc ( MAMSL), Chichinauhtzin (, Xitle (, Cerro Pelado ( and Cuauhtzin (.

List Of Volcanoes In Mexico
Types of volcanoes There are multiple types of volcanoes in Mexico. Volcanoes can be of different types such as cinder cone volcanoes, composite volcanoes, shield volcanoes, and lava domes. Each of these variations of volcanos forms in its own way. Cinder cone volcanoes are the simplest type of volcano. This volcano forms from particles of solidified lava that ejected from a single vent. When the lava is eruptive and blows into the air, it separates into small fragments that solidify and fall around the central vent to form an oval cone at the top of the volcano. “Composite volcanoes or stratovolcanoes, make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi.” These volcanoes are very steep sided and symmetrical, in a cone shape. They have a conduit system which allows the magma to flow from deep within the Earth’s surface. They have many vents within the volcano which allows the lava to break through the walls, which allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cuicuilco
Cuicuilco is an important archaeological site located on the southern shore of Lake Texcoco in the southeastern Valley of Mexico, in what is today the borough of Tlalpan in Mexico City. Some historians believe this settlement goes back to 1400 BC.PASTRANA, Alejandro and Patricia Fournier''Cuicuilco. In The Oxford Encyclopedia of Mesoamerican Cultures''.The Civilizations of Mexico and Central America. Vol. 1. David Carrasco (ed.), pp. 290–292. New York: Oxford University Press. 2001 Other historians believe the pyramid could be the oldest building in the Americas circa 6,500 BC. Cuicuilco flourished during the Mesoamerican Middle and Late Formative (c. 700 BCE – 150 CE) periods. Today, it is a significant archaeological site that was occupied during the Early Formative until its destruction in the Late Formative. Based on its date of occupation, Cuicuilco may be the oldest city in the Valley of Mexico and was roughly contemporary with, and possibly interacting with, the Olm ...

Ajusco
Ajusco is a lava dome volcano located just south of Mexico City, Mexico, in the Tlalpan borough of the city. It is the highest point in the city. Etymology Ajusco is a Náhuatl word variously translated as "source of waters" or "watered grove", and the Lerma River and Balsas River draw some of their source waters from this area. Also, the flow from all of the remaining strong springs in the area adjacent to the peak are captured to augment Mexico City's water supply. Geology Ajusco is a lava dome complex of Pliocene-Pleistocene age, surrounded by block and ash flow deposits. Ajusco is part of the mountain chain of volcanic origin known as Sierra de Ajusco-Chichinauhtzin, among which Xitle (), Tláloc (), Pelado (), Cuautzin () and Chichinautzin () stand out. This range is part of the Trans-Mexican Volcanic Belt which crosses central Mexico and contains the country's highest peaks. Ecology Parts of this range account for about half of the area of the Mexican Federal District, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
