Thunder results from the rapid expansion of air along a lightning strike.

A thunder storm is one in which a large amount of thunder is heard. Thunder is caused by lightning; it would be more correct to say that a thunderstorm only occurs with lightning strikes.
count time in seconds from lightning flash to first peal of thunder. each second is roughly 1000 feet. Use actual speed of sound, a stopwatch, and calculator for more exact answer.
Scientific law - the lightning 'spark' produces a sound wave when it discharges - which is what we hear as thunder.
If you mean hearing thunder right after a lightning, it is because sound travels slower than light, and thus, you would hear the thunder a bit later than seeing a lightning strike.
Typically, thunder can be heard up to 10 miles away from a lightning strike. Sound travels much slower than light, so there is a delay between seeing the lightning and hearing the thunder.

No. Thunder is the noise that lightning makes.
If it is a thunderstorm, you check how long it takes to hear the thunder after you see a lightning strike. For every five seconds, the lightning strike is about one mile away. The lightning causes the thunder, and the sound travels at a speed of about one mile per five seconds.
you are probably hearing the thunder from a different lightning strike.
Lightning can strike and kill you, or start fires. Thunder can't hurt anyone.

It's popularly known as "heat lightning," but meteorologists will tell you that there is really no such thing as a type of lightning that produces no thunder and is distinct from lightning that produces audible thunder. All lightning produces thunder, but it can only be heard for a distance of at most 15-20 miles under normal conditions. At night in certain conditions, lightning can be visible 125 miles away. You may not be able to hear the thunder because you are too far from the storm, but others within that 15 mile radius can hear thunder following the lightning strike.
Light is virtually instantaneous over any distance you'd be aware of a thunderstorm going on. Sound, however, takes five seconds to travel through air for each mile. If the thunder and the lightning are simultaneous, the lightning strike is very close to you. If the thunder is five seconds after the lightning, the lightning was one mile away. If the thunder is ten seconds after the lightning, the lightning was 2 miles away, and so on.
