Gravity for two reasons * The water moves from a higher region to a lower one (mostly for rivers) * The moons gravity causes high a low tide, this pull the water up then drop it causing the water to stir around in currents (this is mostly for oceans)
A difference between gyres and currents is that currents are formed by the wind, but gyres are formed by currents.
from winds :)
the ocean .

Sponge bob has nothing to do with it.
From the uneven heating of the earths surface
Cumulonimbus clouds are formed by strong convection currents. These clouds are tall and dense, often associated with thunderstorms and heavy rainfall.
No, tides are caused by the gravitational pull of the Sun and Moon, not by currents.
they are formed by the air currents above the oceans
No
where do warm and cold currents begin?warm from the mid ocean ( equator )cold North and South pole
