Wind
Yes, winds are examples of convection currents. The uneven heating of Earth's surface by the sun creates temperature variations that cause air to rise and fall, creating convection currents that result in winds.
The sun is major source of energy that power surface currents because the sun causes wind to blow and winds cause surface currents to form
Global winds do not directly cause deep currents. Deep ocean currents are primarily driven by differences in water density, which are influenced by temperature and salinity. While global winds can indirectly affect the distribution and movement of deep currents through their impact on surface currents and mixing processes, they are not the primary driving force.
The three factors which control surface currents are the following:Global windsContinental deflection and temperatureThe Coriolis effect

3/4 of Earth is ocean
winds
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.

surface current
Winds and ocean currents move water parallel to Earth's surface. Winds can create surface currents through friction with the ocean's surface, while ocean currents are driven by a combination of factors such as wind, temperature, salinity, and the Earth's rotation.
