Which weathering product accelerates plant colonization on basalt?

A)Clay mineral formation
B)Oxidized iron accumulation
C)Dissolved calcium precipitate
D)Silica concentration enrichment

💡 Explanation

Clay formation through weathering creates fine-grained material with water-retention, promoting plant rooting via pedogenesis; rather than iron oxides or silica, clay enhances soil structure because the physical and chemical weathering releases minerals necessary for plant life.
