Temperature differences
Earth's tilt
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

Voltage causes current to flow in an electric circuit.
An electric current is caused by the movement of electrically charged particles, typically electrons, through a conductor like a metal wire. This movement can be driven by a voltage difference or potential between two points in the circuit, which exerts a force on the charged particles and causes them to flow.

Voltage causes current to flow in an electric circuit.
A electrical from a battery is the flow of elecrons through a circuit in the opposite dirrection to the current flow. This current flow also happens inside the battery between the plates.
The buzzer work with a magnetic coil that attractes the armature thus interrupting the current. This happens repeatedly to cause the buzz. When the current is interrupted the action of the coil produces a voltage that tries to maintain the current, and that causes a spark between the switch contacts.
Electromotive force (potential difference, voltage) between two points of a conductor.
