Tidal Power Tides arise from the rotational motion of the earth
{"Image DocumentName": "Tidal Power Tides arise from the rotational motion of the earth", "Image ImageDescription": "> differential gravitational field set up by the Earth, Moon, and Sun. Several different tidal cycles:- a semi-diurnal cycle - period 12 hrs 25 mins. a semi-monthly cycle - (i.e. Spring - Neap Tides) corresponding with the position of the moon. Sun, Earth and Moon in approximate alignment >> Spring Tides, a semi-annual cycle - period about 178 days which is associated with the inclination of the Moon s orbit. Causes highest Spring Tides to occur in March and September. Other long term cycles - eg a nineteen year cycle of the Moon. Spring Tides have a range about twice that of neap tides, while the other cycles can cause further variations of up to 15%", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
