Mycology : Fungi :: Pedology : ? — Identify the scientific field’s object of study.

Introduction / Context:
Discipline-to-object analogies map a field of study to what it examines. “Mycology : Fungi” specifies the study of fungi. Pedology is likewise a formal scientific field; we must select its subject matter.

Given Data / Assumptions:

• Mycology → fungi.
• Pedology is commonly defined in earth/soil sciences (context disambiguates from child psychology usage in rare contexts).

Concept / Approach:
In general science/GK contexts, “pedology” denotes the study of soils (their formation, classification, mapping). Hence the correct mapping is “pedology : soil.”

Step-by-Step Solution:
Maintain mapping: field → primary object of study.Select “Soil.”

Verification / Alternative check:
Earth science curricula: pedology focuses on soil genesis, morphology, classification.

Why Other Options Are Wrong:

• Moon/Kidney/Child/Plant: Astronomy, anatomy, developmental psychology, and botany—different fields.

Common Pitfalls:
Confusing “pedology” with “pediatrics” or child-related terms due to similar prefixes; note “pedo-” from Greek “pedon” (soil).

Final Answer:
Soil
