THE THIRTEEN ORIGINAL STATES, WITH THE ACCESSIONS OF TERRITORY GRANTED BY THE TREATY OF 1783 WITH GREAT BRITAIN. TIDES. Tides are caused by the gravitational attraction or pull of the sun and moon upon the water and upon the earth itself. The close relation which the tides of high water bear to the times of the moon's meridian passage shows that the moon's influence in rising tides is much greater than that of the sun; it has been estimated that it is two and one-half times as great. The result of this attraction of the moon is to draw or heap up the water, in the parts of the earth nearest it, successively towards it. The surface of the earta rises and falls twice in a lunar day of about 24 hours and 52 minutes. The tides do not always rise to the same height, but every fortnight, after the new and full moon, they become much higher than they were in the alternate weeks. These high tides are called spring tides, and the low ones neap tides. |
