Question
Wind erosion may be carried out in the following ways:
Choose the correct option from the following codes:
- Deflation
- Abrasion
- Attrition
Choose the correct option from the following codes:
Answer: Option C
Answer: (c)
Wind erosion may be carried out through deflation, abrasion and attrition :
Deflation: This involves the lifting and blowing away of loose materials from the ground.
Abrasion: The sand-blasting of rock surfaces by winds when they hurl sand particles against them is called abrasion.
Attrition: When wind-blown particles roll against one another in a collision they wear each other away so that their sizes are generally reduced and grains are rounded into millet seed sand, the process is called attrition.
