It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
Conduction, convection, and radiation describe methods of heat transfer. Conduction is heat transfer through direct contact, convection is heat transfer through the movement of fluids or gases, and radiation is heat transfer through electromagnetic waves.
Convection is the process whereby heat is transferred by the mass movement of molecules from one place to another.
In a natural convection process, hot air rises at a speed of about 1-3 feet per second.
Convection is the transfer of heat through the movement of fluids (liquids or gases). This occurs as hot fluids rise and cold fluids sink, creating a continuous flow of heat transfer. Convection is an important process in the Earth's atmosphere, oceans, and interior.
Steaming is not the same as convection. Steaming is the process of cooking food with hot steam, while convection is a method of heat transfer in which heat is transferred through the movement of a fluid, such as air.
no.
Lake freezes first at the surface is convection involved

You don't transfer convection. Rather, convection is a process whereby heat energy is transferred.
In convection less molecules occupy large volume as in air to reduce the density.
The process of heat transfer involved in boiling water is primarily convection, where hot water rises and cooler water sinks, creating a circulation that evenly distributes heat. In heating your house, both convection and radiation are at play; convection circulates warm air throughout the space, while radiation transfers heat from radiators or heating elements directly to objects and surfaces in the room. Both processes work together to maintain a comfortable temperature.

All of them.
convection
The process is called convection. Convection is the transfer of heat through the movement of fluids, such as wind or water, from one place to another.
In this process, heat is transferred by the bodily movement of particles of the medium due to difference in densities of different parts of the medium. convection process is also slow.
