Explanation:

Convection currents occur due to temperature differences. When a fluid (liquid or gas) is heated, it expands, becomes less dense, and rises. The cooler, denser fluid then sinks to replace it. This continuous cycle of rising and sinking forms convection currents. The greater the temperature difference, the more vigorous the convection currents.

Answer:

Convection currents are driven by temperature differences. A temperature difference causes a density difference in a fluid. The warmer, less - dense fluid rises, and the cooler, denser fluid sinks, creating a continuous flow (convection current). Larger temperature differences lead to stronger convection currents.
