Tides

Why isn't the mediterranean tidal if some large lakes are?

The tides are caused by the gravitational action of the sun and moon upon the rotating earth. Theoretically all the stars, planets and satellites in the universe produce separate and distinct tides, but their influence, of course, cannot be detected. The moon is nearly two and a quarter times more potent as a tide-producing agent than the sun, because the tide-generating force of a body depends not only on its mass but also on its distance from the earth.Although their effect may not always be appreciable, the tide-producing forces exert themselves on all bodies of water in proportion to their size and depth, even on ponds and pools.It is not true, as sometimes stated, that there are no tides in such bodies as the Mediterranean Sea and the Great Lakes. The same forces produce tides in these bodies, but their area is relatively small and the tides are so slight that they are generally masked by differences in mean level resulting from winds, changes in atmospheric pressure, and the discharge of rivers.
At Chicago the tide in Lake Michigan rises only about two inches. The subject of tides is exceedingly complex because of the motions of the earth and moon and because the actual operation of the tide-producing forces is modified by numerous local factors, particularly the location and configuration of the oceans.

i live in S italy smack bang in the middle of the mediteranian and can assure u that there r tides in the medditeranian but not as large as u may get in the UK. when we go to the seaside (15 minutes away - don't u envy me hehe) the beach gets up to 2 metres longer as the tide goes out that is of course a small tide but still a tide
