Table of Contents

A. When Allende entered Earth's atmosphere, it broke into thousands of pieces

called chondrites because they look like glassy, black seeds.

B. The mineral content of chondrules suggests that they were probably formed in

isolated regions of the nebula that remained much hotter than the rest.

C. Chondrules are tiny, millimeter-sized drops of silicate materials that

probably formed when lumps of nebular dust were fused at extremely high

temperatures and then quickly cooled.

D. Irregularly shaped inclusions in Allende are composed of minerals that are

resistant to melting and are believed to be the earlest minerals to have

condensed out of the nebula.

E. The matrix that holds the chondrules and inclusions together in Allende

consists mainly of grains of nebular dust that were trapped inside the

meteor before they could be melted.

F. Except for being depleted in volatile elements, chondritic meteorites are

probably very similar in composition to the matter from which planets were

assembled.
