Which of the following processes contributes to the mineral content of soils?
A
Weathering of rocks
B
Condensation of water vapor
C
Evaporation of water
D
Photosynthesis in plants
Verified step by step guidance1
Understand the concept of weathering: Weathering is the process by which rocks are broken down into smaller particles, which can contribute to the mineral content of soils. This process can be physical, chemical, or biological.
Consider the role of condensation: Condensation is the process by which water vapor in the air is changed into liquid water. This process does not directly contribute to the mineral content of soils.
Evaluate the effect of evaporation: Evaporation is the process by which water changes from a liquid to a gas or vapor. While it affects the water content in soil, it does not add minerals to the soil.
Analyze the process of photosynthesis: Photosynthesis is the process by which plants use sunlight to synthesize foods with the help of chlorophyll. It primarily involves the conversion of carbon dioxide and water into glucose and oxygen, and does not contribute minerals to the soil.
Conclude that weathering of rocks is the process that contributes to the mineral content of soils, as it breaks down rocks into mineral-rich particles that become part of the soil.
