The sea breeze and land breeze occur in nature due to which of the following mode of heat transfer?

The land ‘or’ sea heats the air above it by convection. 
The warm air expands and becomes less dense decreasing the pressure over land ‘or’ sea.
The air travels from the region of high pressure to these regions of low pressure creating a land breeze or sea breeze.

Therefore, we can say that the sea breeze and land breeze are created due to convection.
