What causes the electrons to move and form static electricity?
moist air
dry air
friction

Answers

Answer:

friction

Explanation:

The rubbing of certain materials against one another can transfer negative charges, or electrons.

The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.

What is static electricity ?

Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.

These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.

The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.
