Yucatan peninsula



The Yucatán Peninsula (Spanish: Península de Yucatán), in southeastern Mexico, separates the Caribbean Sea from the Gulf of Mexico, with the northern coastline on the Yucatán Channel. The peninsula lies east of the Isthmus of Tehuantepec, a northwestern geographic partition separating the region of Central America from the rest of North America.

The peninsula comprises the Mexican states of Yucatán, Campeche, and Quintana Roo; the northern part of the nation of Belize; and Guatemala's northern El Petén Department.

Etymology

The proper derivation of the word Yucatán is widely debated. Hernan Cortes, in the first of his letters to Charles V, the Holy Roman Emperor, claimed that the name Yucatán comes from a misunderstanding. In this telling, the first Spanish explorers asked what the area was called, and the response they received, "Yucatan," was a Yucatec Maya word meaning "I don't understand what you're saying." [1][2] Others claim that the source of the name is the Nahuatl (Aztec) word Yokatlān, "place of richness."

People

The Yucatán Peninsula comprises a significant proportion of the ancient Maya Lowlands (although the Maya culture extended south of the Yucatán Peninsula, through present Guatemala and into Honduras and highland Chiapas). There are many Maya archaeological sites throughout the peninsula; some of the better-known are Chichen Itza, Tulum and Uxmal.[3] Indigenous Maya and Mestizos of partial Maya descent make up a sizable portion of the region's population, and Mayan languages are widely spoken there.

Economy

In the late historic and early modern eras, the Yucatán Peninsula was largely a cattle ranching, logging, chicle and henequen production area. Since the 1970s (and the fall of the world henequen and chicle markets due to the advent of synthetic substitutes), the Yucatán Peninsula has reoriented its economy towards tourism, especially in the Mexican state of Quintana Roo. Once a small fishing village, Cancún in the northeast of the peninsula has grown into a thriving city. The Riviera Maya, which stretches along the east coast of the peninsula between Cancún and Tulum, houses over 50,000 beds and is visited by millions of tourists every year. The best-known locations are the former fishing town of Playa del Carmen, the ecological parks Xcaret and Xel-Há and the Maya ruins of Tulum and Coba.

"During the past 150 years, the economy of the Yucatán peninsula has been largely shaped by three factors: the Caste War, henequen production, and tourism. The Caste War of 1847 was an indigenous Maya rebellion against the social organization imposed by the Spanish. This rebellion defined the geography of the regional economy. After the Caste War the Maya controlled the southeastern part of the peninsula and the people of Spanish descent controlled the rest. Market-oriented activities were predominantly carried out in the northwestern region, while a traditional milpa system was the principal economic activity in the central and southern areas."[1]

Geology

The peninsula is the exposed portion of the larger Yucatán Platform, all of which is composed of [2]

According to the Alvarez hypothesis, the mass extinction of the dinosaurs at the transition from the Cretaceous to the Paleogene Period, the Cretaceous–Paleogene boundary (K–T boundary), 65 million years ago was caused by an asteroid impact somewhere in the greater Caribbean Basin. The deeply buried Chicxulub Crater is centered off the north coast of the peninsula near the town of Chicxulub. The now-famous "Ring of Cenotes" (visible in NASA imagery) outlines one of the shock-waves from this impact event in the rock of ~65 millions years of age, which lies more than 1 km below the modern ground surface near the centre, with the rock above the impact strata all being younger in age. The presence of the crater has been determined first on the surface from the Ring of Cenotes, but also by geophysical methods, and direct drilling with recovery of the drill cores.

Water resources

Due to the extreme karst nature of the whole peninsula, the northern half is devoid of rivers. Where lakes and swamps are present, the water is marshy and not palatable for drinking water. Due to its coastal situation, the whole of the peninsula is underlain by an extensive contiguous density stratified coastal aquifer, where a fresh water lens formed from meteoric water floats on top of intruding saline water from the coastal margins. The thousands of sinkholes known as cenotes throughout the region provide access to the groundwater system. The cenotes have long been relied on by ancient and contemporary Maya people.[4]

Vegetation

Short and tall tropical jungles are the predominant natural vegetation types of the Yucatan Peninsula. The boundaries between northern Guatemala ([3]

Climate

Like much of the Caribbean, the peninsula lies within the Atlantic Hurricane Belt, and with its almost uniformly flat terrain it is vulnerable to these large storms coming from the east. The 2005 Atlantic Hurricane Season was a particularly bad season for Mexico's tourism industry, with two forceful category 5 storms hitting, Hurricane Emily and Hurricane Wilma. The 2006 Atlantic Hurricane Season was a typical year which left the Yucatán untouched, but in the 2007 Atlantic Hurricane season Yucatán was hit by Hurricane Dean (also a category 5 storm), nevertheless Dean left little damage on the peninsula despite heavy localized flooding.

Strong storms called nortes can quickly descend on the Yucatán Peninsula any time of year. Although these storms pummel the area with heavy rains and high winds, they tend to be short-lived, clearing after about an hour. The average percentage of days with rain per month ranges from a monthly low of 7% in April to a high of 25% in October. Breezes can have a cooling effect, [4]
