The proper derivation of the word Yucatán is widely debated. Hernán Cortés , 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." Others claim that the source of the name is the Nahuatl (Aztec) word Yocatlān, "place of richness."

The peninsula comprises the Mexican states of Yucatán ,
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
The peninsula is the exposed portion of the larger Yucatán Platform
, all of which is composed of carbonate and soluble rocks, being
mostly limestone although dolomite and evaporites are also present at
various depths. The whole of the Yucatán
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 ~66 million 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.
The Arrowsmith Bank is a submerged bank located off the northeastern end of the peninsula.
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 generally unpotable. 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.

Short and tall tropical jungles are the predominant natural
vegetation types of the Yucatán Peninsula. The boundaries between
