Levelsand is a fictional material used in worldbuilding, video games, and speculative geology to describe a stratified, multi-layer substrate. It is characterized by stacked layers that collectively form a single surface but display distinct internal properties.
Structure and properties: Each layer has its own grain size distribution, density, cohesion, and friction. Porosity,
Etymology: The name levelsand is a portmanteau of levels and sand, signaling the idea of layered, granular
Applications in fiction and games: In interactive media, levelsand enables multi-layer terrain where players traverse laterally
Educational and research use: As a simplified model, levelsand helps illustrate phenomena related to layered granular
