What is the meaning of earth, water, wind and fire in Buddhism?

Water, fire, wind and earth are the four elements. When I die, I feel bad all over. Then I'm incontinent. Then my breathing stops. .It is the disappearance of the wind. Finally, my body temperature drops. When I am cool, the four elements are gone. ． ． ． ． There are also three disasters, that is, at the end of the tribulation, first there is a flood that floods from hell to the first Zen heaven, then there is a fire which also burns from hell to the second Zen heaven, and finally, there is a disastrous wind that blows from hell to the third Zen heaven, and the world is destroyed, then starts again.
