A friend of mine once overheard a conversation between a father and his child on a public transit bus on a windy day. Child: "Why does the wind blow?". Father: "Some places are cold and some places are warm. That is not fair. Thus, the wind takes the cold air away and moves it to the warm place so that everybody's happy." - IRO-bot, from Earth Science ...

I know that 'Blowing air is called Wind' but what I don't know is, how is wind formed? And I don't want the answer from Google Search. I want to know more about wind in atomic or molecular level It is not out of a quirk of physicists that even though we have an enormous knowledge of how the microscopic framework of atoms and molecules works, we still ...

When a region heats, and another region somewhere cools it creates a difference in pressure. Hot air rises, and it then goes towards the region of low pressure to equal the pressure at both regions. Now, why does the air rise? I mean, why hot air rises. A simple explanation is: Hot air is less dense and experiences a buoyant force, just like a bubble of ...

Basicaly, atmospheric wind are created from pressure differences from one area respective to another, so air molecule are pushed toward the lower pressure zone. This air molecules movement is called "wind". One application of this simple principle can be described by the so called Venturi effect derived from Berbouilli's equation $$ P*_\text {1} + ...

Lightning conductors on tall buildings are designed to be hit by lightning multiple times, and photographic evidence proves that it does.

I would have thought that actually it is quite the contrary. Some places are far more likely to get hit by lightning than others, and repeatedly. That is why tall buildings have lightning conductors.

There is no scientific law that says that and it's definitely false. There are two reasons why it's unlikely to see lightening strike the same place twice: 1) The earth is really big, and lightening strikes will occur pretty randomly. 2) Lightening (cloud to ground or vice versa) occurs after there's a charge buildup between a point in the sky and a point ...

It is neither physical nor statistical. It is simply not true. On the contrary, lightning can hit more than once during one single thunderstorm, due to the channel that has opened in the first strike. David pointed towards one source.
