Which of the following best describes a burial vault?

A burial vault is best described as a heavy container that surrounds the casket in the grave. This container serves multiple important purposes: it protects the casket from the weight of the earth above it, helps to maintain the integrity of the grave site, and prevents the ground from settling over time. Burial vaults are constructed from robust materials like concrete or metal, ensuring durability and stability in the burial process. They play a crucial role in the overall burial procedure and protect the casket and its contents from external elements, contributing to the dignity and preservation of the remains.
