Answer 2

Lightning:

• It is a electrostatic discharge.

• It is a spontaneous release of energy which is values around one Gigajoule.

Causes of lightning:

• Clouds are accumulation of water vapour. Water molecules are rubbed with each other and charged due to friction.
• Top of clouds are positively charged and bottom of clouds are negatively charged.
• So, the bottom of the cloud have negative charge and lands/roof of building have positive charges (less electrons). When these to come closer, the negative charges moves towards positive charges.
• This causes a flash which is lightning.
