Mud cracks.

Transient mud cracks can promote plant survivorship by trapping seeds, and enhance germination and growth by increasing water infiltration in the soil, thus facilitating the formation of a persistent salt marsh landscape. Cracks can help the salt marsh withstand more intense droughts, leading to postponed collapse and faster recovery. Well-preserved mud cracks, sole marks, and raindrop impressions can be used to determine up direction. Other useful geopetal structures include: Vugs: Small voids in the rock that usually become filled during diagenesis. Drywall mud, also called joint compound, is a gypsum-based paste used to finish drywall joints and corners in new drywall installations. It's also handy for repairing cracks and holes in existing drywall and plaster surfaces. Drywall mud comes in a few basic types, and each has its advantages and disadvantages.
