Re: World's noise





Well, there are several ideas in there; let's take them separately.

A1) If we take the word "while" literally, then the answer is that the
world does make a big noise !while! rotating, and we most certainly can
hear it. I can hear waves crashing on the seashore. I can hear wind
whistling through the trees. I can hear animal activity and human
activity. Et cetera. All this goes on !while! the world is rotating.


Yes, :-) . My student meant did the earth create noise just because of
its rotation, as you guessed in A2. It was a cause-effect relation.
Cause: The earth rotates, effect: noise? He actually was looking for if
there was such a cause and effect relation. Do you think that all the
sounds (except the ones created by human activities such as speaking,
concerts etc.) like the crashing waves on the earth has a symetrical
relation with the rotation?
