Noun
ejecta pl (plural only)
(geology) Material which has been ejected, especially from a volcano or an impact crater.
A notable basin is the 400 km wide, multi-ring Tolstoj Basin that has an ejecta blanket extending up to 500 km from its rim and a floor that has been filled by smooth plains materials. Source: Internet
As ejecta escapes from the growing crater, it forms an expanding curtain in the shape of an inverted cone; the trajectory of individual particles within the curtain is thought to be largely ballistic. Source: Internet
As such there is a discontinuity in the definition of the VEI between indices 1 and 2. The lower border of the volume of ejecta jumps by a factor of 100 from convert while the factor is 10 between all higher indices. Source: Internet
Around 2001, the expanding (>7000 km/s) supernova ejecta collided with the inner ring. Source: Internet
Although the energy that disrupts each type of supernovae is delivered promptly, the light curves are mostly dominated by subsequent radioactive heating of the rapidly expanding ejecta. Source: Internet
Beethoven Basin has a similar-sized ejecta blanket and a 625 km diameter rim. Source: Internet
