What is the purpose of spreading dry leaves in a shelter made in a rocky forest?

Spreading dry leaves in a shelter constructed in a rocky forest serves the critical function of creating an insulation layer. This layer helps to trap body heat, which is essential for maintaining warmth in cooler temperatures, particularly during the night or in a cold environment. Dry leaves are excellent insulators because they contain air pockets between them, which reduces heat loss and can help make the shelter more comfortable for anyone seeking refuge from harsh weather conditions.

While other options might seem plausible, they do not align with the primary survival needs when constructing a shelter. Maintaining cleanliness or preventing pests are secondary considerations that might be addressed in a different context but are not the main purpose of using dry leaves in this scenario. Enhancing aesthetic appearance is not relevant in survival situations, where warmth and safety are prioritized.
