Dry or waterlogged conditions will generally have what effect on organic artifacts?

Dry or waterlogged conditions will generally result in cracks on organic artifacts.

Waterlogged organic artefacts are unstable when found and sensitive to rapid changes in environmental conditions, which, if not carefully controlled, can

lead to the deterioration of artefacts upon excavation Uncontrolled drying of organic materials and outbreaks of mould on

them can lead to the loss of archaeological evidence
