Explanation:

Weather (wet and dry periods) plus additional natural occurrences-- chip off small bits of minerals from different types of rocks.

These particles are known as “parent material.The dimension and chemical makeup of the parent material establishes the characteristics of the topsoil, such as its types or pH levels.

For soil to be living it must be covered, and this takes place naturally when plants' roots spread throughout the soil and hold it in place. Suitable disturbances, whether natural or manmade, form stronger plants. The strong plants will hold the topsoil in place allowing it to form properly.
