yes they do it has pressure witch does not make water smooth i do not think you would like it if you were a fish
They create currents and micro climates for different sea life.
Directional changes in ocean currents affect marine life because sea creatures often migrate using the currents. When the currents shift, it becomes more difficult for the sea creatures to find their way back. Also, ocean currents carry tiny plankton and other small organisms that sea creatures eat. Ocean currents can either take away these plankton, or bring many more in, depending on which way the current is going.
"Currents affect fish by bringing in rubbish, dirty water, and other stuff"
Lava lamps.
Yes, the thermohaline currents will be affected.
convection currents rush cool air to the sea
it affects everything
they dont
Ocean currents from the South are warm. This makes the cities in the South of Italy have a warm climate. There are hardly any ocean currents affecting the North of Italy because there is no sea.
It's more likely the other way around. Ocean currents affect ocean life. Perhaps in a subtle way, since all life on the planet affects the atmosphere, especially the algae in the oceans releasing oxygen, that ocean life affects the weather, which in turn affects the ocean currents. It's also possible that some "seaweed forests" slow the movement of currents.

It gives us hot and cold temperatures on earth.
