Introduction

• Soil erosion can be defined as the wearing away of land surface by running water, wind, ice or other geological agents including such processes as gravitational creep.
• In other words, it is the process of detachment and movement of soil particles or rocks from one place to another by some agents including human being activities.

Types of soil erosion

1. Geological or normal erosion:

• Refers to erosion of land in its natural environment without the influence of human beings.
• caused by the action of water, wind, temperature variation, gravity and glasciers.
• takes place steadily but so slowly that ages are required for it to make any marked alternation in the major features of the earth’s surface.

2. Accelerated erosion:

• refers to removal of the surface soil from areas denuded of their natural protective covers results of human and animal interference takes place at a much faster rate than that at which it is buildup by the soil forming process.
