Static electricity is the buildup of electric charges. Which of the following is an example of a natural discharge of static electricity? A. northern lights B. Earth's magnetic poles C. lightning D. ocean waves

Answer: The correct answers are electricity and discharge.

Explanation:

Van de Graaff generator is an electrostatic generator. It is used for producing high voltage static electricity. It consists of a hollow metal sphere. The charges is accumulated on it from continuous motion of the belt which is made of an insulating material.

Due to polarization, the charges builds up on an object. Van de Graaf generator is an example of static charge.

Static discharge occurs when the built-up charges flow from the object. Lightning is an example of static discharge. Lightning occurs when the clouds having an opposite charges collide each other.

Therefore, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightening is an example of static discharge.

The answer is: C

This is because of clouds in the sky, there may be a positive charged cloud and a negative charged cloud, when both clouds come together they form a neutral cloud so the protons and electrons in both clouds become equal in one bigger cloud and the excess amout of electrons is the lighting.
