Answer :
Convection currents are influenced by the physical characteristics of the air because warmer air rises because it is less dense than cooler air.
What role do the physical characteristics of the air play in convection currents?
Warm, lighter (less dense), and rising matter rises while cool, heavier (more dense), falling matter sinks. Convection currents are the circulation patterns that are produced by this movement in the Earth's atmosphere, water, and mantle. Air in the atmosphere rises as it warms, allowing cooler air to enter from below.
In order to produce temperature differences, convection relies on regions of a liquid or gas heating up or cooling down faster than those around them. Then, as a result of these temperature differences, the areas move as the hotter, less dense areas rise and the cooler, denser, sink.
