*Ordinarily means:* A sequence of events where one event triggers the next.

A single cause sets a parameter beyond a wall, which enables another cause to act where it could not before, and so on.

## Emergence
**Emerges from:** [cause](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-cause.reason), [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [interaction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interaction.process), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless)

**Through:** interaction.process

**Novel properties:**
- chain reaction
- stacked dependency

## Examples
- In the 2008 financial crisis, the collapse of Lehman Brothers triggered a cascade of credit freezes across global banks. *(economics)*
- The Chernobyl reactor's power surge caused a steam explosion that ruptured containment, exposing the core and releasing radiation. *(engineering)*
- Prion misfolding in mad cow disease propagates as each distorted protein induces errors in neighboring healthy proteins. *(biology)*
