An insulating plate, such as plastic, tends to be positively charged when rubbed with cloth due to the piezoelectric effect. This phenomenon involves certain materials to generate charged particles as a response to mechanical stress applied to it. In this case, the mechanical stress was due to the rubbing motion.
The practice of forming step-like fields on steep slope is called : Terracing
Terracing was created to enhance the farming activities in the area that would increased the farming activity as whole, such as irrigation system, soil structure, etc
