-
Pedology
-
Edaphology
-
Soil Ecology
-
Agrogeology
Correct Answer
A. EdaphologyExplanation
Edaphology is the branch of soil science that studies the influence of soils on living things. This field explores the dynamic interactions between soil and organisms, emphasizing the impact of soil properties on plant growth, microbial activity, and overall ecosystem health. Understanding the role of soils in supporting life is essential for sustainable land management and biodiversity conservation efforts.Rate this question:

What is soil compaction?
-
Enrichment of soil with nutrients
-
The process of soil erosion
-
Stress causing densification of soil
-
Soil becoming less able to absorb rainfall
Correct Answer
A. Stress causing densification of soilExplanation
Soil compaction is the process in which stress applied to soil causes densification, reducing its ability to absorb rainfall and increasing runoff and erosion. This phenomenon adversely affects soil structure, limiting its porosity and hindering essential processes such as water infiltration, root growth, and nutrient availability for plants, ultimately impacting ecosystem health.Rate this question:

How does soil act as a natural filter for groundwater?
-
Allowing contaminants to pass through to groundwater
-
Absorbing and retaining contaminants
-
Preventing the infiltration of water into the ground
-
Promoting the leaching of pollutants
Correct Answer
A. Absorbing and retaining contaminantsExplanation
Soil acts as a natural filter for groundwater by absorbing and retaining contaminants present in water as it infiltrates into the ground. This filtration process is crucial for maintaining groundwater quality, as soil particles and organic matter trap and immobilize pollutants, preventing them from reaching and contaminating groundwater sources. Understanding soil's role as a natural filter underscores its significance in purifying and safeguarding vital water resources.Rate this question:
