The name of the site is: Hoyo Negr*o
The site is located in the underwater cave of Mexican Yucatan Pennisula. In that site, scientists have found the what they considered as the oldest skeleton in America (which is around 10,000 - 12,000 years old)
In spanish, the site is translated as "the black hole" because it's located in a very scary dark pit.
When you heat air it expands. When air expands it becomes less dense than the air around it, in turn making it rise.
