How does friction contribute to a lightning strike?
Any process that causes separation of positive and negative charges in the atmosphere can cause lightning. Lightning occurring during thunderstorms is thought to be the result of vertical motions causing charge separation. Ice particles typically will hold a positive charge in the upper part of the cloud, while liquid water will hold a negative charge in the lower part of a cumulonimbus cloud. When charge difference gets too great lightning results. This is an oversimplification as there are other more complex processes that occur with severe rotating thunderstorms. To top it of cloud to ground lightning can be either a positive stroke or a negative. Still some mysteries there. I'll stop here so as to not cause any friction.
Does lightning come from the clouds?
The source of lightning in thunderhead clouds is when there is a significant amount of ice in the cloud, most likely hail and there are 2 differing charges in 2 areas. The negative charge is at the bottom of the cloud, while the positive charge is at the top of the cloud. The ground is positively charge until there is an electrical discharge between the negatively charged cloud base and the positively charged ground, then it becomes mostly negative which then can open up the opportunity for a lightning bolt to jump from the top of the cloud, all the way down to the ground in another electrical discharge that is of greater electrical potential (voltage) than the first electrical discharge between the cloud base and the ground. This is because it takes more voltage to have a visible electrical discharge over a longer distance. There has to be 30,000 volts/cm of distance for a visible electrical discharge to occur.
Lightning forms when charges drop to the lower parts of a cloud and charges build up on the ground below?
When clouds become charged due to the separation of positive and negative charges, lightning can occur when the electrical imbalance is released as a bolt of electricity. This discharge can happen within a cloud, between clouds, or from a cloud to the ground.
Does wind shear separate the positive and negative charges in a cloud?
Wind shear will usually blow away the ionized air. A separation of charges in a cloud occurs, and allows the electric potentials to increase to an extent that a neutralizing discharge must occur, which comes in the form of lightning.
How does the phenomenon of lightning, which typically goes from the ground up, occur in the atmosphere?
Lightning occurs when electrical charges build up in the atmosphere, usually during a thunderstorm. The negative charges gather at the bottom of the cloud, while positive charges accumulate on the ground below. When the difference in charge becomes strong enough, a channel of ionized air forms, allowing the electrical discharge of lightning to travel from the cloud to the ground.
How can you have thunderstorms without lightning?
Thunderstorms typically include lightning as a result of electrical discharge between clouds or between a cloud and the ground. However, in some cases, thunderstorms can occur without visible lightning due to certain weather conditions, such as the absence of sufficient charge separation or the lightning occurring within the cloud itself, known as "intra-cloud" lightning.
Why many lightning strikes occur within a cloud rather than between clouds and the ground.?
Many lightning strikes occur within a cloud due to the presence of strong electric fields created by the separation of positive and negative charges within the cloud. This charge separation leads to the buildup of energy that discharges as lightning when the potential difference becomes large enough. The dense concentration of water droplets and ice particles in clouds facilitates this process, allowing for frequent intra-cloud discharges compared to the less common inter-cloud or cloud-to-ground strikes. Additionally, the short distances involved within the cloud make it easier for the discharge to occur.
How does charge separation occur in a system and what impact does it have on the overall functioning of the system?
Charge separation occurs when positive and negative charges are separated within a system, creating an electric field. This can happen through various processes such as friction or chemical reactions. The impact of charge separation on the overall functioning of the system is significant, as it can lead to the generation of electrical energy, which can be harnessed for various purposes such as powering devices or transmitting signals.
What were electrical storms called?
The electric storm is commonly known as thunder.In an electrical storm, the storm clouds are charged like giant capacitors in the sky. The upper portion of the cloud is positive and the lower portion is negative. How the cloud acquires this charge is still not agreed upon within the scientific community. However, it could be explained as follows:When there is a charge separation in a cloud, there is also an electric field that is associated with the separation. Like the cloud, this field is negative in the lower region and positive in the upper region. The strength or intensity of the electric field is directly related to the amount of charge buildup in the cloud. As the collisions and freezing continue to occur and the charges at the top and bottom of the cloud increase, the electric field becomes more and more intense. it is so intense, in fact, that the electrons at the earth's surface are repelled deeper into the earth by the strong negative charge at the lower portion of the cloud. This repulsion of electrons causes the earth's surface to acquire a strong positive charge. The strong electric field, being somewhat self-sufficient creates a conductive path for the negative cloud bottom to contact the positive earth surface.
What 3 ways can lightning occur?
Lightning can occur when positively and negatively charged particles within a cloud separate, creating an electrical imbalance that is discharged as a bolt of lightning. It can also occur between different clouds or between a cloud and the ground when the charge buildup is released. Additionally, lightning can occur during volcanic eruptions when ash particles in the plume become charged and generate lightning.
Why do electric discharges occur?
Electric discharges occur when there is a buildup of electrical charge in a material or between two materials with different electrical potential. When the electrical resistance is overcome, the stored charge is released in the form of a spark or visible discharge.

Where in the atmosphere does lightning occur?
Negative charge accumulates on the bottom of a cumulonimbus cloud and becomes attracted to the positive charge of the ground. When it overcomes air resistance, the charges shoot down. The lightning that you see is when the positive charge shoots back up into the cloud.
Does wind shear separate the positive and negative charges in a cloud?
