thanks for updating us and this is little bit info about the ocean events. coasts and other masses, like dams of granite, deflect the
flow of currents. Currents bumping into the continents must change direction
and flow toward the equator or the pole. Only the Antarctic circumpolar current
can flow unimpeded around Earth. 

A pressure gradient is a change of pressure across a horizontal
distance. Water that is piled up in a mound creates a zone of high pressure.
The water responds by flowing down the pressure gradient. The steeper the
gradient is, the faster the flow of water. ccsp dumps The less steep, the less speed
the water or you will have. When the water first starts to flow from high
to low pressure, the coriolis force is weak. But as the flow goes faster,
the Coriolis force becomes strong enough to balance the pressure gradient.
When this happens, the flow goes around the high pressure area. You might ask, " How does water mound up? Isn't the
ocean always flat? " The answer to your second question is, " No!
" If you could walk across the watery surface of the ocean you would
find yourself moving up hills and down into valleys. ccvp dumps Far too small to see
by casual observance, the hills are usually no more than 1 m (3 ft) high over
a space of 100 km (60 miles). The hills might be only 1 meter high measured
from the valley but they have a very important effect on ocean currents.
Now, back to your first question--How does water in the ocean mound up? Read
on, please.
Steady winds blowing on the sea surface produce a thin,
horizontal layer at the sea surface called the his layer may be 10 m, 50 m, or at most 100 m thick. This may
not sound " thin " to you, but when compared to the depths of the
ocean--it is thin. ciw dumps Each layer of the ocean affects the layer beneath it through
its movement. Each successively deeper layer moves at a slower speed than
the layer above and moves, in the northern hemisphere, slightly to the right
of the layer above. The change in direction is created by the coriolis effect
and is known
