## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [area](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-area.spatial), [form](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-form.shape), [surface](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surface.exterior)

**Through:** matter together with a boundary creates an area of surface

**Novel properties:**
- bounded extent
- surface configuration
- spatial enclosure

## Examples
- The Ganges River delta grows 50 square kilometers per year as sediment meets the Bay of Bengal's edge. *(geography)*
- Mount Everest's surface rose 0.8 meters between 1995 and 2020 due to tectonic uplift and ice accumulation. *(geophysics)*
- The Netherlands' coastline extends 7 kilometers westward since 1850 through dikes enclosing seabed. *(engineering)*
