Convection in gases occurs because when a gas is heated, its molecules gain energy and move faster, becoming less dense and rising. This creates a convective current as cooler, denser air is pulled in to replace the rising warm air. This process of heat transfer helps circulate the air and distribute heat evenly in a space.
A convection current, however, this can also occur with gases.

Convection heat transfer occurs in fluids and gases when warmer particles rise and cooler particles sink, creating a circular motion that transfers heat. This process is driven by differences in density caused by temperature variations within the fluid or gas.
Convection only occurs in fluids. Fluids are gases or liquids.
A pot of boiling water is a good analogy for convection. As the water at the bottom heats up, it becomes less dense and rises to the top. Cooler water then replaces it at the bottom, creating a continuous circulation pattern. This is similar to how convection currents work in fluids and gases.
A convection current, however, this can also occur with gases.
In liquids by convection and by radiation in gases
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.

The temperature of gases in the convection zone increases as they rise towards the top. This is due to the process of convective heat transfer, where hotter gases move upwards and cooler gases move downwards, creating a cycle that leads to temperature increase towards the top of the convection zone.
