We deal with it by means of mathematical abstractions which rest on the notions of disorder and energy. Presenting an explanation of these concepts together with a brief account of their origins. 1954 Scientific American, Inc.doi:10.1038/scientificamerican09251909-215aNoneScientific American...

Lightning is caused by electricity building up inside a cloud. When a large amount of warm air and cold air come together high above the earth, it causes a lot of movement in the air. The cold air moves down while the warm air moves up, which creates something like friction (摩擦) ....
What is lightning? Lightning is the bright flash of light or electricity that is caused by a thunderstorm. When protons have built up in the cloud, they attract oppositely charged protons around them. This means that positively charged particles on the ground below will attract the negatively cha...
When you see lightning you usually also hear thunder. The two go hand in hand. Thunder is a really loud noise. It is caused by the cold and hot air meeting and causing it to expand and heats up to temperatures that are more than 54,000 degrees F and is approximately 6 times hotter ...
What is lightning attracted to? What is tear gas made of? What is wind shear in meteorology? What is heat of combustion? What is detonation in an internal combustion engine? What is hypoxia caused by? Wind power generates what kind of pollution?
Lightning Lightning is a naturally occurring phenomenon that releases one gigajoule of energy because of electrostatic discharge. There are three types of lightning: cloud to ground, cloud to air, and cloud to cloud. Answer and Explanation:
when lightning is made the same thing happens, but on a much bigger scale. below, we have listed points sequentially on how or why lightning occurs. lightning can be explained in terms of charges produced due to rubbing. during a thunderstorm, the air currents move upwards and the ...
