Lightning also causes thunder, a sound from the shock wave which develops as heated gases in the vicinity of the discharge experience a sudden increase in pressure. The most common occurrence of a lightning event is known as a thunderstorm, though they can also commonly occur in other types of energetic weather systems, such as volcanic eruptions.

The more of the animal's body that is submerged while swimming, the less energy it uses. Swimming on the surface requires two to three times more energy than when completely submerged. This is because of the bow wave that is formed at the front when the animal is pushing the surface of the water when swimming, creating extra drag. [34]
Undulatory locomotion is the type of motion characterized by wave-like movement patterns that act to propel an animal forward. Examples of this type of gait include crawling in snakes, or swimming in the lamprey. Although this is typically the type of gait utilized by limbless animals, some creatures with limbs, such as the salamander, forgo ...
The movement of aircraft through clouds can even cause lightning strikes. [3] A single lightning event is a "flash", which is a complex, multistage process, some parts of which are not fully understood. Most CG flashes only "strike" one physical location, referred to as a "termination".
Sheet lightning is cloud-to-cloud lightning that exhibits a diffuse brightening of the surface of a cloud, caused by the actual discharge path being hidden or too far away. The lightning itself cannot be seen by the spectator, so it appears as only a flash, or a sheet of light. The lightning may be too far away to discern individual flashes.
A storm that pummeled dozens of Midwest states with snow during the weekend also brought another weather phenomena, at least to Missouri: Thunder and lightning.. The phenomenon, known as ...
(Water is a polar molecule that can carry a charge, so it is capable of creating the charge separation needed to produce lightning). [108] These electrical discharges can be up to a thousand times more powerful than lightning on the Earth. [109] The water clouds can form thunderstorms driven by the heat rising from the interior.
