Kneading
Pressing
Tamping
Vibration
Answer is Right!
Answer is Wrong!
The correct answer is: A. Kneading
Sheep foot rolling is a type of soil compaction that uses a sheep foot roller to compact the soil. The sheep foot roller is a heavy, cylindrical roller with a series of projections that resemble sheep’s feet. The projections are designed to penetrate the soil and compact it.
The basic action involved in sheep foot rolling is kneading. Kneading is a process of applying pressure to the soil and then moving the soil in a circular motion. This action helps to break down the soil aggregates and create a more uniform soil structure.
The other options are incorrect because they do not describe the basic action involved in sheep foot rolling.
- Pressing is a process of applying pressure to the soil without moving it. This action does not help to break down the soil aggregates or create a more uniform soil structure.
- Tamping is a process of applying pressure to the soil with a tool such as a tamper. This action helps to compact the soil, but it does not break down the soil aggregates.
- Vibration is a process of applying a shaking motion to the soil. This action can help to break down the soil aggregates, but it is not the basic action involved in sheep foot rolling.
