What is tides
  • 1 answers

Yogita Ingle 4 years, 8 months ago

  • The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide.
  • Movement of water caused by meteorological effects (winds and atmospheric pressure changes) are called surges.
  • Surges are not regular like tides.
  • The ‘tide-generating’ force is the difference between these two forces; i.e. the gravitational attraction of the moon and the centrifugal force.
  • On the surface of the earth, the horizontal tide generating forces are more important than the vertical forces in generating the tidal bulges.
  • The tidal bulges on wide continental shelves, have greater height. When tidal bulges hit the mid- oceanic islands they become low.
  • The shape of bays and estuaries along a coastline can also magnify the intensity of tides. Funnel-shaped bays greatly change tidal magnitudes. When the tide is channeled between islands or into bays and estuaries they are called tidal currents.
