Wwhat caused lightning

Dear Student, Water from the sea evaporates and drifts upward due to the low density of the vapor, and forms clouds. During the upward journey, they acquire electric charge due to friction. These charges are accumulated in such a manner that the positive charges are accumulated on top of the cloud and negative charges are accumulated on the bottom. The air is an insulator of electricity. When two clouds come near, or the potential difference between the cloud and the ground is too high, then the air between the clouds or between the cloud and ground undergoes dielectric breakdown and conducts electricity. This flow of electricity is known as lightning. In other words, When liquid and ice particles above the freezing level collide. This then builds a large electrical field in the clouds, which create electric spark due to friction in layers of charge particles. The temperature of Lightning can reach fifty thousand degrees Fahrenheit, which is hotter than the surface of the sun. The heat is produced in the form of light. Regards
