What happens to a body in a casket buried?

When a body is buried in a casket, it undergoes a natural decomposition process over time. Initially, the body may be preserved for a period due to the airtight seal of the casket, which limits exposure to air and moisture. Eventually, bacteria and microorganisms break down the tissues, leading to the release of gases, and the body will decompose into organic matter. Depending on environmental conditions and the materials of the casket, this process can take several years to decades.
