Understanding Word Relationships: Pedology and Soil

The question asks us to identify the option that shares the same relationship as the given pair of words: Pedology : Soil.

Let's first understand the relationship between Pedology and Soil.

• Pedology is a scientific discipline that studies soil in its natural setting. It focuses on the origin, evolution, description, and mapping of soil.
• Therefore, the relationship between Pedology and Soil is that Pedology is the study of Soil.

Analysing the Options for Study of Relationships

Now we need to examine each option to see which pair exhibits the same 'study of' relationship.

Option 1: Seismology : Pressure

• Seismology is the scientific study of earthquakes and seismic waves that move through and around the Earth.
• Pressure is a measure of the force applied perpendicular to the surface of an object per unit area.
• Seismology is not the study of pressure. The relationship here is incorrect based on the given pair.

Option 2: Pomology : Fruits

• Pomology is a branch of botany that studies fruits and their cultivation. It includes the study of fruit structure, development, storage, and processing.
• Fruits are the sweet and fleshy products of a tree or other plant that contain seed and can be eaten.
• Pomology is the study of Fruits. This relationship matches the relationship between Pedology and Soil.

Option 3: Cytology : Metabolism

• Cytology is the study of cells, including their structure, function, and life cycle.
• Metabolism is the set of life-sustaining chemical transformations within the cells of living organisms.
• Cytology is not the study of metabolism. While metabolism happens within cells, cytology studies the cells themselves. The relationship is incorrect.

Option 4: Hepatology : Blood

• Hepatology is the branch of medicine that deals with the study, prevention, diagnosis, and management of diseases that affect the liver, gallbladder, biliary tree, and pancreas.
• Blood is a bodily fluid that transports necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
• Hepatology is not the study of blood. It focuses on the liver and associated organs. The relationship is incorrect.

Comparing Relationships and Finding the Match

Let's summarise the relationships:

Option 2, Pomology : Fruits, is the only pair that exhibits the same 'study of' relationship as Pedology : Soil.

Additional Information: Branches of Science

Many scientific fields are named with a suffix indicating 'study of'. Understanding these names helps in various analogy questions.

• '-logy' is a common suffix meaning 'study of' or 'science of'. Examples include Biology (study of life), Geology (study of the Earth), Zoology (study of animals), Botany (study of plants), etc.
• Understanding what specific '-logy' fields study is key to solving such analogy questions based on scientific disciplines.
• Other related terms might use different suffixes, but the principle of identifying what is being studied remains the same.
