? 9~ ? • Where The Water Goes at Low Tide. The natural answer to this question would be to say that at low tide the water goes to the place that is at the same time experiencing a high tide; but if I tell you that you will just as wise as you were before.-. Let me explain therefore. Firstly, of course, the water in the sea is always somewhere! It doesn’t suddenly dry up to make low tide. What has happened is that it has gone to some other part of the earth. You see, the earth spins under the pull of the sun aricl moon, and the water the earth is always being moved about. When we see the tide rising it is simply the water being heaped up in one part of the globe, mainly under the influence of the moon. But if it is heaping up in one place the water must be drawn from somewhere else. At that place the tide is therefore ebbing. This solution of course accounts for the fact that tides rise at various places at different times. It would be impossible for all spots by the sea to experience a high tide at the same time—unless, of course the world started bulging all round! And let’s hope that won’t happen yet awhile.
