Temperature differences Earth's tilt
Global convection currents are caused by the unequal heating of Earth's surface by the Sun. As the Sun's rays strike the equator more directly, the air at the equator becomes warmer and rises, creating a low-pressure area. This warm air then moves towards the poles and cools, sinking at around 30 degrees latitude, creating high-pressure areas that flow back towards the equator, completing the convection loop.
The main causes of convection in the asthenosphere are heat generated from the Earth's core, radioactive decay of elements within the Earth, and the movement of tectonic plates. As the material in the asthenosphere is heated unevenly, it becomes less dense and rises, while cooler, denser material sinks, creating a convection current.
Actually, there are many ways for a convection current to form. So, if you asked this question, here is one way:A convection current forms when Hot air and Cold air form a cycle and mix. . .That's one way!ToodlesByee
The thermal convection that drives plate motion is caused by the movement of molten rock in the mantle. Heat from Earth's core causes the mantle to circulate in a convection current, which in turn drags the overlying tectonic plates along with it, driving plate motion.
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

convection
Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides). When the oceans are deep, convection within the layers can also affect the flow of currents. * While wind currents are greatly affected by uneven heating of the Earth's surface, there is no corresponding heating of the ocean bottom by the Sun. So currents do not form spontaneously at depth.

Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
