A destructive plate boundary.
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.
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.
That is the current theory of plate tectonics.
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
In geography, a convection current refers to the movement of air or water in the atmosphere or oceans caused by the uneven heating of the Earth's surface. This movement helps distribute heat energy around the globe, influencing weather patterns and climate. Convection currents play a key role in the Earth's energy balance and the circulation of heat.

When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.

I learned what convection means in science class.
Sea floor spreading is caused by convection currents in the mantle to cause a divergent boundary underwater. When the divergent boundary spreads, it caues a mid-ocean ridge. This is sea-floor spreading. Hope I helped!
That is the current theory of plate tectonics.
The circular motion is called convection current.
The core of the earth contains radioactive material and this causes a convection current in the mantle.
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.
