What does cremation involve?

Cremation involves the reduction of the body through fire. This process typically occurs in a cremation chamber, where the body is exposed to high temperatures, leading to the combustion of organic materials and the evaporation of moisture. The result is the transformation of the body into ashes, which are collected afterward. This method is an alternative to traditional burial practices and is chosen for various reasons, including environmental concerns, cost, or personal preference.

The other options represent different methods of body disposition. Burial of a casket refers to the interment of a deceased individual in the ground, which is a traditional method. Natural decomposition in the earth refers to the process by which a body breaks down naturally over time when buried, while preservation of the body with chemicals typically involves embalming, which is done for viewing prior to burial or cremation. These alternatives contrast with the process of cremation, further emphasizing the unique characteristics that define it.
