Factors that affect the formation of tides in the Ocean are1. Alignmen...
Justification: Statement 1 and 2: The strong gravitational pull exerted by
the sun and the moon on the earth’s surface causes the tides.
The water of the earth closer to the moon gets pulled under the influence of
the moon’s gravitational force and causes high tide.
• During the full moon and new moon days, the sun, the moon and the
earth are in the same line and the tides are highest. These tides are
called spring tides.
• But when the moon is in its first and last quarter, the ocean waters
get drawn in diagonally opposite directions by the gravitational pull
of sun and earth resulting in low tides. These tides are called neap
tides.
Statement 3: The shape of bays and estuaries also can magnify the
intensity of tides. Funnel-shaped bays in particular can dramatically alter
tidal magnitude.
• The Bay of Fundy in Nova Scotia is the classic example of this effect,
and has the highest tides in the world - over 15 meters.
• Narrow inlets and shallow water also tend to dissipate incoming
tides.
• In estuaries with strong tidal rivers, such as the Delaware River and
Columbia River, powerful seasonal river flows in the spring can
severely alter or mask the incoming tide.
Statement 4: Strong offshore winds can move water away from coastlines,
exaggerating low tide exposures.
• Onshore winds may act to pile up water onto the shoreline, virtually
eliminating low tide exposures.
• High-pressure systems can depress sea levels, leading to clear sunny
days with exceptionally low tides.
• Conversely, low-pressure systems that contribute to cloudy, rainy
conditions typically are associated with tides than are much higher
than predicted.
