Lightning is an electrical discharge between charged particles in a cloud and charged particles within the ground or in another cloud. This results in the bright streak of light that is seen in the sky that is known as lightning.
When liquid water gains enough energy, the water particles move faster and break away from one another. The water's volume increases. This is how water vapor forms. Water vapor has a lower density than liquid water, so it moves...
Lightning is an electrical discharge between charged particles in a cloud and charged particles within the ground or in another cloud. This results in the bright streak of light that is seen in the sky that is known as lightning.
When liquid water gains enough energy, the water particles move faster and break away from one another. The water's volume increases. This is how water vapor forms. Water vapor has a lower density than liquid water, so it moves upward in the sky. Some water vapor condenses onto dust particles in the air. When there are enough dust particles surrounded by condensation, a cloud forms.
The water droplets that make up clouds are not stationary. Rather, they move around and may bump into one another. This movement may result in the droplets becoming charged. Opposite charges migrate towards opposite sections of a cloud. The positively charged particles move to the top of the cloud, and the negatively charged particles move to the bottom of the cloud. Once the division of opposite charges becomes extreme enough, the opposite charges attract one another at the same time that the "electrical potential" develops between earth and cloud. The result is a an electrical discharge and the spark that we know as lightning.
