Electrostatic forces can play a role in spider dispersal according to a recent study. The correct statement among the options is:
- The positively charged atmosphere attracts negatively charged spider silk.
This phenomenon is based on the principle of electrostatic attraction, where opposite charges attract each other. The spider silk, being negatively charged, is attracted to positively charged particles in the atmosphere, aiding in the dispersal of spiders through a process known as ballooning. Ballooning is a behavior in which spiders release silk threads into the air, and the electrostatic forces generated help lift and carry the spiders over long distances, facilitating their dispersal.
