One topic, as StudyPath teaches it.
The topic focuses on what soil is, how it is defined scientifically, and the main ideas used to describe soil as a natural body that supports plant growth and performs many environmental functions. For the exam, you must clearly distinguish soil from loose rock or dirt, understand the factors that give soil its identity, and explain why soil is both a medium for plant growth and a dynamic part of the earth system.
