Ocean Currents surface current factors: wind belts, rotation, and location of continents Coriolus effect causes gyres, clockwise in Northern hemisphere Gulf stream is important climate factor deep currents result from density differences turbidity currents caused by underwater landslides, carry sediments V. Waves wave speed = wavelength / period wind is main source of wave energy large waves tend to grow larger, into swells size factors: wind speed, length of time wind blows, fetch of wave fetch is distance wind can blow across open water breakers move sediments along shores, erode cliffs refraction causes waves to strike shore head-on despite original direction longshore currents cause sand erosion and depositon tsunamis are caused by underwater earthquakes and landslides VI. Tides both sun and moon affect tides, moon is stronger influence high tides caused on both sides of the earth in line with moon spring tides occur when sun and moon in line, neap when at right angles tides affected by nature of ocean basin oscillations may increase tidal effect, as in Bay of Fundy tidal currents known as flood and ebb tides tidal bores can rush up rivers Climate Notes What causes climate?
