Impacts into porous asteroids
Witryna27 mar 2024 · Fine-grained matrix regions are highly porous, especially when compared with non-porous or low-porosity chondrules, and during impacts, the pore spaces collapse, creating temperature and pressure excursions (Bland et al., 2014; Davison et al., 2016), which allow for grain realignment and deformation in response to the … WitrynaEffects: If the asteroid hits on land, there would be a huge amount of dust thrown up into the atmosphere. If it hits in water, then there would be an increase in water vapor …
