# sand (material)

small pieces of matter that together form a surface in a place

- Computed level: L10 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [size](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-size.measurement), [piece](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-piece.portion), [small](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-small.size), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [surface](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surface.exterior), [form](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-form.shape)

**Through:** small pieces of matter, each with limited extent, arrange together in space to form a continuous surface with a shape not present in any individual piece.

**Novel properties:**
- collective surface formation
- emergent shape
- granular continuity

## Examples
- The Sahara Desert spans 9.2 million square kilometers, its surface shaped by wind-driven quartz grains under persistent erosion. *(geography)*
- The 1941 construction of the Mulholland Dam used 600,000 tons of concrete mixed with beach sand from the nearby Santa Clara River. *(engineering)*
- Children at Tokyo's Haneda Airport playground mold volcanic sand from Mount Fuji into shapes that collapse under their own weight. *(everyday life)*
