Which term is associated with the preservation of remains using natural processes?

The term that is associated with the preservation of remains using natural processes is mummification. This process can occur under specific environmental conditions, such as arid climates, where the natural drying of the body inhibits decay and preserves it for extended periods. Mummification can happen without any artificial substances being introduced, relying instead on the natural elements to prevent decomposition.

In contrast, embalming involves the introduction of chemicals to delay decomposition and preserve the body artificially. Decomposition refers to the natural breakdown of organic matter, which is the opposite of preservation. Autolysis is a process where the body begins to self-digest due to enzymatic activity after death, leading to decomposition rather than preservation. Each of these terms describes different processes related to the handling of remains following death, but mummification specifically highlights the preservation achieved through natural means.
