Tides and their Causes
- TIDES AND THEIR CAUSES
- Tide is the periodical rise and fall of sea water.
- The interval between two tides is 12 hrs and 26 minutes.
- Through both sun and moon exert gravitational force on earth, resulting in the production of tides, the moon, by nature of its closeness to the earth, has greater control over the timings of the tidal rises and falls.
- Causes: (1) The moon’s attraction (2) The centrifugal force. Tide is caused by the difference in these two forces.
- Spring tide
- When the rise and fall of the water are the highest. It is known as the spring tide. It si caused when the sun and the moon are in a strength line. It takes place on new moon and full moon days.
- Neap tide
- When the rise and all of the water are the lowest. It takes as the spring tide. It is caused when the sun and the moon are in a strength line. It takes place on new moon and full moon days.
