The Yucatan Peninsula was created after the impact of a meteorite 10 kilometers in circumference which hit the Gulf of Mexico 65 million years ago, leaving a 180 km crater called Chicxulub.
Only half of the crater is located within the peninsula, the rest is located on the seabed of the Gulf of Mexico. Within the peninsula buried under 10 km of limestone and bordered by a strange semicircular grouping of 90 km radius with 99 cenotes called the ring of cenotes.
The impact triggered a chain reaction, which among its effects ended the era of the dinosaurs.
As for the Yucatan Peninsula, it emerged from the ocean, due to the sediment from the seabed that was expelled as a result of the impact, and little by little as it went down it accumulated, until it surpassed the surface of sea level, the sun solidified it, creating the karst soil characteristic of the peninsula.
What is karst?
It is a type of landscape dominated by relatively soluble rocks such as limestone.
The limestone rocks of Yucatán are composed mainly of Calcite mineral formed by calcium carbonate (Calcium carbon and oxygen) this is the main component of shells, skeletons of many organisms and egg shells.
It is characterized by depressions on the surface and drainage systems with sinkholes and caves in the subsoil.
