how does lightning form
Most lightning occurs within the … Evaporation is the process by which a liquid absorbs heat and changes to a vapor. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground. Thunderstorms have very turbulent environments. Lightning forms when the electrons in the bottom of a cloud are attracted to the protons in the ground. When the attraction of these electrical charges is greater than the surrounding air's resistance to electrical flow, the electrons are able to stream down to the protons. The main bolt or stroke will go back up to the cloud. It will make a flash of lightning. When air continues to rise, the cloud gets bigger and bigger. As the air rises, water vapour cools and forms a cloud. At this point, lightning forms, heating the air around it and causing the air to expand. Lightning is an electric current. Or, a leader stroke can go from the cloud to another cloud. Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy. Lightning causes thunder, a sou… Strong updrafts and downdrafts occur with regularity and within close proximity to each other. This lightning bolt of energy that is let out is called a leader stroke. When the ground is hot, it heats the air above it. This discharge may produce a wide range of electromagnetic radiation, from very hot plasma created by the rapid movement of electrons to brilliant flashes of visible light in the form of black-body radiation.
To make this electric current, first you need a cloud.
It can go from the cloud to the ground.
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves.
To fully understand how the water cycle works, we must first understand the principles of evaporation and condensation. Lightning begins with a process that's less mysterious: the water cycle. No one is sure why lightning bolts follow a zigzag path as they move. This warm air rises. The accumulation of electric charges has to be great enough to overcome the insulating properties of air. Wh… The updrafts transport small liquid water droplets from the lower regions of the storm to heights between 35,000 and 70,000 feet, miles above the freezing level.Meanwhile, downdrafts transport hail and ice from the frozen upper regions of the storm.
