What are the types of degradation?

Introduction

• Types of soil degradation. Soil degradation can be classified into four main types of degradation: water erosion, wind erosion, chemical deterioration and physical deterioration.
• Water erosion.
• Wind erosion.
• Chemical deterioration.
• Physical deterioration.
• Human causes of erosion.
• Control of erosion.
• Conclusion.

What are the causes of degradation in India and Brazil?

Overgrazing, soil degradation, land clearance, climatic changes, excess pollution, depletion of “soil nutrients” through “poor farming practices”, excessive cutting of trees, infrastructure development are the main causes of forest degradation in India.

What causes polymer degradation?

In general, the effects of heat, light, air and water are the most significant factors in the degradation of plastic polymers. The major chemical changes are oxidation and chain scission, leading to a reduction in the molecular weight and degree of polymerization of the polymer.

What are the main causes of land degradation in India Class 10?

Nine Main Causes of Land Degradation are as follows:

• Deforestation: Forests play an important role in maintaining fertility of soil by shedding their leaves which contain many nutrients.
• Excessive Use of Fertilizers and Pesticides:
• Overgrazing:
• Salination:
• Water-logging:
• Desertification:
• Soil erosion:
• Wasteland:

What are major causes of degradation of forest in India?

What is engineering degradation?

In engineering, degradation is defined as a loss of the relevant properties of materials which proceeds gradually due to exposure to in-service conditions. Human body can also be considered as one of the in-service environments for engineering components.

What are the four main ways to degrade material?

Degradation Mechanisms

• microstructural and compositional changes,
• time-dependent deformation and resultant damage accumulation,
• environmental attack and the accelerating effects of elevated temperature, and.
• synergistic effects among the above.
