In April 1815, the cataclysmic eruption of Mount Tambora in present-day Indonesia injected massive quantities of sulfur dioxide into the stratosphere, where it reacted to form highly reflective sulfate aerosols. Over the following months, global wind currents dispersed these aerosols, creating a stratospheric veil that blocked incoming solar radiation. The resulting drop in global temperatures triggered the 'Year Without a Summer' in 1816, causing unseasonal frosts and torrential rains that devastated agricultural yields across Europe and North America. Among the hardest-hit crops was oats, the primary source of feed for draft animals. The subsequent feed shortage caused a catastrophic decline in the horse population, leaving communities without their primary mode of transportation and agricultural labor. In urgent need of a mechanical alternative, German inventor Karl Drais designed the 'Laufmaschine'—a steerable, two-wheeled wooden vehicle propelled by human foot power. This device, which laid the foundation for the modern bicycle, stands as a clear example of how a localized geological event can initiate a cascade of cause-and-effect relationships culminating in major technological innovation.
Based on the passage, arrange the following events in the correct order to represent the cause-and-effect chain that led to the invention of the Laufmaschine, starting with the initial cause and ending with the final effect.
- 1Mount Tambora erupts, releasing vast quantities of sulfur dioxide into the stratosphere.
- 2Sulfate aerosols disperse globally and block incoming solar radiation.
- 3Severe agricultural disruption leads to a critical shortage of oats.
- 4A scarcity of feed results in a sharp reduction in horse populations.
