Are caves hotter or colder?
The temperature in caves tends to stay the same year-round, because they’re underground and not affected by surface weather patterns. The temperature of a cave is usually close to the average annual temperature for the region where it’s located. For example, caves in Texas can be as warm as 70º F.

How hot is the deepest cave?
In extreme cases, wind speeds can hit 70 mph. Perhaps one of the most bizarre cave climates on Earth is found in the Cueva de los Cristales (Cave of Crystals) in Mexico. In this deep cave 980 feet below the surface, air temperatures can hit 136 degrees and humidity can top 90 percent.
What do caves smell like?
The high levels of sulfur that create the gas in Colorado’s Sulphur Cave come from deep within the earth. The cave is formed in travertine, a type of stone formed by deposits from streams and mineral springs. Hydrogen sulfide gas, which gives the cave its rotten-egg smell, can be deadly at high concentrations.
Can you suffocate in a cave?
For decades, speleologists have trained inside CJ-3, a 164-foot-deep cave in Cañon del Río Lobos Natural Park in the Soria province. But in 2014, visitors to the cave experienced something new at the bottom: they nearly suffocated, and one person fainted. The oxygen levels had suddenly, and inexplicably, dropped.
How did early humans make fire?
If early humans controlled it, how did they start a fire? We do not have firm answers, but they may have used pieces of flint stones banged together to created sparks. They may have rubbed two sticks together generating enough heat to start a blaze. Conditions of these sticks had to be ideal for a fire.

Can caves run out of oxygen?
Would they not run out of oxygen by the time they can get out? Most cave systems are relatively permeable. Even if you can’t see a route out, there are likely to be paths for air movement. The immediate threat is the accumulation of carbon dioxide rather than a deficit of oxygen.
