Material thrown out from a volcano, meteor impact, or other source; rock and ash ejected explosively from a source.
From Latin 'ejectus,' the past participle of 'eicere' (to throw out), with the neuter plural form '-a' used as a mass noun in scientific terminology.
When a meteor hit Earth 66 million years ago, the ejecta from that impact blocked the sun and killed the dinosaurs—this scientific word describes the most consequential thrown objects in Earth's history!
