B. Distinguish between each of the following pairs.
1. Degradation and aggradation
2. Weathering and erosion
3. Granular disintegration and exfoliation
4. Hydration and solution
5. Soil erosion and soil conservation
Answers
Answer:
Aggradation refers to an increase in elevation of land usually in river system due to deposition of sediments.
Degradation occurs due to erosional activities of mainly wind and water. It refers to the lowering of a landform through erosional process.
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion
Granular Disintegration: When the agents of weathering, reduce rocks made up of different minerals to small pieces and fragments, it is called granular disintegration. ... Water then enters into the cracks and the outer layer of the rock peels off. This is called exfoliation
The formation of a solution involves the interaction of solute with solvent molecules. Many different liquids can be used as solvents for liquid solutions, and water is the most commonly used solvent. When water is used as the solvent, the dissolving process is called hydration. The interaction between water molecules and sodium ion is illustrated as one of the diagram below. This is a typical ion-dipole interaction. At the molecular level, the ions interact with water molecules from all directions in a 3-dimensional space. This diagram depicts the concept of interaction only
Soil erosion is the detachment, transportation, and deposition of soil particles. Natural erosion is generally slow, keeping pace with soil formation rates. ... Soil conservation is the practice of minimizing soil loss while maximizing agricultural production.
