what processes happen at the surface of the sea?

Answer 1

Hello,

(ANS) Actually the processes that take place on the sea's surface are alot more complex than you might at first think.

a) evapouration of water into water vapour & into clouds, this evapouration is precisely what drives our wheather systems here on earth.

b) The evapouration of the sea water into water vapour increases the levels of salinity (saltiness) in the oceans. This changes the density of the sea water, more salt in the sea water makes it denser (heavier).

c) increased salinity in the oceans is what drives ocean currents like the gulf stream. The gulf stream is what keeps the west side of the UK a couple of degree's warmer than it would otherwise be, so our wheather is directly affected by the prescence of the gulf stream.

d) Our wheather is affected directly by water evapouration and ocean currents, here in the UK our wheather is direclty affected by the Atlanic ocean. i.e. westerly anti cyclones, depressions & storms.

e) Water evapouration also helps to create wind (wind is caused by the flow of air between high & low pressure systems, again over the oceans).

f) Wind will contribute to wave development and the intensity of those waves, again linked to wheather & storm systems.
