Florida has alot of air pockets underneath the ground. I've watched a documentary on the weather channel before. Air pockets below the ground slowly erode and eventually open up at the top layer of the ground, causing the earth to open up.
The times of moonrise and moonset are based on ideal situations. The time of moonrise is calculated based on the fact, when the top part of the moon is above the horizon. The moonset time is considered as the time when the moon is just about to go below the horizon. I hope the answer helps you.
Explanation:
The physical environment of forests is determined by edaphic (soil) factors and micro-climate (precipitation, light, temperature, and wind). Gas-exchange within forest canopies depends upon the microclimatic condition within the forest, as well as, edaphic factors and water availability.
