Maya civilizationThe Maya civilization (ˈmaɪə) was a Mesoamerican civilization that existed from antiquity to the early modern period. It is known by its ancient temples and glyphs (script). The Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. The civilization is also noted for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador.
Chicxulub craterThe Chicxulub crater (tʃikʃuˈlub) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore near the community of Chicxulub, after which it is named. It was formed slightly over 66 million years ago when a large asteroid, about in diameter, struck Earth. The crater is estimated to be in diameter and in depth. It is the second largest confirmed impact structure on Earth, and the only one whose peak ring is intact and directly accessible for scientific research.
Yucatán PeninsulaThe Yucatán Peninsula (ˌjuːkəˈtɑːn, also UKˌjʊk-, US-ˈtæn,_ˌjuːkɑːˈtɑːn; Península de Yucatán jukaˈtan) is a large peninsula in southeast Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north and west of the peninsula from the Caribbean Sea to the east. The Yucatán Channel, between the northeastern corner of the peninsula and Cuba, connects the two bodies of water. The peninsula is approximately in area.
Chichen ItzaChichén Itzá (often spelled Chichen Itza in English and traditional Yucatec Maya) was a large pre-Columbian city built by the Maya people of the Terminal Classic period. The archeological site is located in Tinúm Municipality, Yucatán State, Mexico. Chichén Itzá was a major focal point in the Northern Maya Lowlands from the Late Classic (c. AD 600–900) through the Terminal Classic (c. AD 800–900) and into the early portion of the Postclassic period (c. AD 900–1200).
MesoamericaMesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to most of Central America, thus comprising the lands of central Mexico, Belize, and Guatemala, El Salvador, Honduras, and Nicaragua, and northern Costa Rica. In the pre-Columbian era, many societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas begun at Hispaniola island in 1493.
SinkholeA sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as vrtače and shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. A cenote is a type of sinkhole that exposes groundwater underneath. Sink and stream sink are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock.
CobaCoba (Cobá) is an ancient Maya city on the Yucatán Peninsula, located in the Mexican state of Quintana Roo. The site is the nexus of the largest network of stone causeways of the ancient Maya world, and it contains many engraved and sculpted stelae that document ceremonial life and important events of the Late Classic Period (AD 600–900) of Mesoamerican civilization. The adjacent modern village bearing the same name, reported a population of 1,278 inhabitants in the 2010 Mexican federal census.
YucatánYucatán (ˌjuːkəˈtɑːn, also UKˌjʊk-, US-ˈtæn,_ˌjuːkɑːˈtɑːn, ɟʝukaˈtan; Yúukatan ˈjúːkatan), officially the Free and Sovereign State of Yucatán, is one of the 31 states which comprise the federal entities of Mexico. It comprises 106 separate municipalities, and its capital city is Mérida. It is located on the northern part of the Yucatán Peninsula. It is bordered by the states of Campeche to the southwest and Quintana Roo to the southeast, with the Gulf of Mexico off its northern coast.
CaveA cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called exogene caves. Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment.
Quintana RooQuintana Roo (kɪnˌtɑːnə_ˈroʊ(oʊ) , kinˈtana ˈro), officially the Free and Sovereign State of Quintana Roo (Estado Libre y Soberano de Quintana Roo), is one of the 31 states which, with Mexico City, constitute the 32 federal entities of Mexico. It is divided into 11 municipalities, and its capital city is Chetumal. Quintana Roo is located on the eastern part of the Yucatán Peninsula and is bordered by the states of Campeche to the west and Yucatán to the northwest, and by the Orange Walk and Corozal districts of Belize, along with an offshore borderline with Belize District to the south.
