This resurge also entrains and deposits ejecta on the crater floor (e.
Multiple lines of evidence show water was present in both the high angle vapour plume and the ejecta curtain created by the LCROSS Centaur impact.
The high-resolution images from the Sim-8 clearly show the cloud of ejecta thrown backwards on impact and also demonstrates that even though the projectile disintegrates on impact, the fragments maintain the original projectile shape ahead of the main fragment cloud.
Wernstedt and Spencer (1967) estimated that nearly 25% of the total land cover in the Philippines was developed from volcanic ejecta such as andesite, basalt, and volcanic ash.

They have also suggested that the thermal energy radiated from re-entering ejecta from K/T impact is likely to have caused global wild fires, leading to the formation of soot.
The sandy ejecta deposit under study has a transitional position between the coarse-grained, mainly carbonate breccia layer and debris-rich carbonate layers of the post-impact cover (Ainsaar et al.
General topics include instrumentation and data analysis, molecular clouds, star formation, solar system and extrasolar planets, circumstellar matter and ejecta, interstellar medium, stars, extragalactic and cosmology.
They based the programme around four environmental effects: thermal radiation, seismic shaking, ejecta (debris gouged from the earth) deposition and air blast.
The program is based on thermal radiation, seismic shaking, ejecta deposition and air blast and was developed by scientists at the University of Arizona.
It will tell if you can expect to burst into flames and be buried under a mountain of ejecta while the ground cracks and trees and buildings for miles around are flattened.
