选项A“positive and negative charges separate”(正电荷和负电荷分离),这是雷电形成的关键因素之一,在云层中正负电荷分离会导致电荷的积累从而引发雷电,这一表述符合雷电成因;选项B“the clouds are white”(云是白色的),云的颜色与雷电形成无关;选项C“there is only one kind of charge”(只有一种电荷),...
Lightning is a natural electrical discharge of very high voltage and current that occurs during thunderstorms. It is a visible flash of light produced by an electrical discharge, which typically occurs within clouds, between clouds, or between a cloud and the ground. Here are various dimensions to...
Lightning occurs most frequently in cumulonimbus clouds, in which case they are called thunderclouds. It sometimes originates in nimbostratus clouds, and also during volcanic eruptions, tornadoes, and dust storms. The most common lightning discharges are linear; they are among the electrodeless discharge...
Lightning is a sudden high-voltage discharge of electricity that occurs within a cloud, between clouds, or between a cloud and the ground. Globally, there are about 40 to 50 flashes of lightning every second, or nearly 1.4 billion flashes per year. These electrical discharges are powerful and ...

Spider lightning is the long, horizontally traveling flashes often seen on the underside of clouds.NOAA Lightning also sometimes leaves the cloud but stays in the sky, a phenomenon that can take many forms. It might jump to another cloud, or it might simply strike the air around the storm ...
Lightning is usually associated with cumulonimbusclouds(thunderclouds), but it also occurs in stratiform clouds (layered clouds with a large horizontal extent), in snowstorms and dust storms, and sometimes in the dust andgasesemitted by eruptingvolcanoes. During a thunderstorm, lightning can occur with...

Whips of lightning cut a dramatic scene across a storm-darkened sky in Patagonia, Argentina. Most lightning occurs within cumulonimbus clouds like these, but it can also be released from wide, layered formations called stratiform clouds. Photograph by William R. Curstinger ...
