How can primary succession cause soil formation?

Hint: Soil is that thin layer of fabric covering the surface and is made from the weathering of rocks. It's made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. Therefore, most living things ashore depend upon soil for his or her existence.

Complete answer:
Soil formation may be a stage in primary succession. After the bare land has been created or newly exposed, hardly organisms called pioneer species are blown or transported in how or another onto the bare land. These species can survive without soil. Pioneer species typically have light seeds that disperse easily through wind. Grasses, mosses, lichens, and other plants are pioneer species.

As these pioneer plants live, attract consumers, and die, soil is either formed or improved to the purpose where other plants will begin to grow. The surface of the bare land can also be eroded by wind, water, and other processes simultaneously, which also contributes to the formation of substrate. this might happen before the pioneer species arrive and it's going to still happen after their arrival if enough surface is exposed.

Note: Primary succession results in conditions nearer optimum for tracheophyte growth; pedogenesis or the formation of soil, and therefore the increased amount of shade are the foremost important processes.
