WebChondrules are spheroidal. They were formed by melting porous clumps of dust in the solar nebula. The spheroidal shapes (like those of water droplets) are the result of surface tension. Mean chondrule sizes range from 0.3 to 1.0 mm. Within each chondrite group they constitute ~50% to 90% of the mass of individual meteorites. WebThe exact process of chondrule formation is still unknown, but there are several leading theories; One theory is that chondrules were formed through rapid heating and cooling … twr09-1a
