## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [structure](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-structure.arrangement), [portion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-portion.share), [form](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-form.shape), [above](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-above.spatial), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [rise](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-rise.movement), [surrounded](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-surrounded.enclosed)

**Through:** change alters a portion of matter’s form, shaping it into a structure that rises above adjacent space

**Novel properties:**
- elevated elevation
- localized prominence
- gradual slope

## Examples
- Mauna Kea rises 10,210 meters from the Pacific seafloor, formed by volcanic activity over millennia. *(geology)*
- The chalk hills of the South Downs in southern England were shaped by glacial meltwater erosion during the last ice age. *(geography)*
- Signal Hill in St. John's, Newfoundland, played a key role in the 1901 transatlantic radio transmission by Marconi. *(technology)*
