How does friction come about using the four forces?
It comes from the electromagnetic interaction of the atoms of the two surfaces rubbing against each other.
I see, but is it because of deformities at the microscopic level or chemical bonds? Essentially what's I'm between. How does the electric force become friction.
When you have a rough surface, it will have many "mountains" and "valleys". Your hand will also have these. When they rub against each other,the electrons of the atoms of your hand's mountains repell the electrons of your rough surface's mountains. This is the force.
Note: I don't mean actual mountains
