Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Fields Of Mexico
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Landforms Of The State Of Mexico
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). 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 oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbod ...

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 Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 State of Mexico, Mexico. It makes up the southern part of the Orography, mountain necklace that surrounds Mexico City. It is made up of more than one hundred volcanic cones, among which are: Mount Tlaloc, Tláloc ( Metres above sea level, MAMSL), Chichinauhtzin (, Xitle (, Cerro Pelado, Tlalpan, Cerro Pelado ( and Cuauhtzin (. Its maximum height is at the Cruz del Marqués peak on the Ajusco volcano (). Background The range includes parts of the Municipalities of Mexico City, municipalities of Tlalpan, Xochimilco, Tláhuac, Milpa Alta and Magdalena Contreras on the south of Mexico City; the municipalities of Huitzilac, Tepoztlán and Tlalnepantla in Morelos; and the municipalities of Juchitepec and Tepetlixpa, in the State of Mexico.

List Of Volcanoes In Mexico
Volcanoes in Mexico form a significant part of the country's geological landscape, with numerous active and extinct volcanoes scattered throughout the nation. These volcanoes are primarily located within the Trans-Mexican Volcanic Belt, a major volcanic arc in North America that extends across central-southern Mexico. The diverse array of volcanic features in Mexico includes stratovolcanoes, shield volcanoes, cinder cones, lava domes, and calderas. Many of Mexico's volcanoes are part of the Pacific Ring of Fire, a region characterized by frequent earthquakes and volcanic eruptions. Notable volcanoes in Mexico include Popocatépetl, one of the country's most active and dangerous volcanoes, Pico de Orizaba (Citlaltépetl), the highest peak in Mexico, and Parícutin, a cinder cone volcano that famously emerged from a cornfield in 1943. Mexican volcanoes play a significant role in the country's geography, climate, and culture, influencing local ecosystems, agriculture, and human settl ...

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. Construction of the Cuicuilco pyramid began a few centuries BCE, during the Late Preclassic period of Mesoamerican history.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 The site was occupied until its destruction by the eruption of Xitle, sometime between 245 and 315 CE. 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 Olmecs of Mexico's Gulf Coast region (also known as the Olmec heartland). Importance Based on known facts, it was the first important civic-religious center of the Mexican Hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
