heat loss through air
Conduction and Convection
Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.
convection
It is called Convection.

Via convection.
Conduction and Convection
Heat from Earth's interior via convection currents.
From the surface, it would be via convection currents
The convection zone in a star like the Sun is located just beneath the photosphere. It is the layer where energy generated in the star's core is transported to the surface via convection currents, providing the energy needed for the star to shine.
Statements of convection typically refer to ideas or observations related to the process by which heat is transferred through a fluid (like air or water) via the movement of the fluid itself. For example, "Convection currents form when warm air rises and cool air sinks."
The sun heats the Earth, and then longwave radiation heats the troposphere via convection currents.
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition
Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.
Trans-density migration motion via gravitational field gradient energy transferal.
Our Earth's outer core consists of a liquid iron, which is highly conductive. As this liquid moves via convection (the same way water boiling in a pot moves via convection), electrical fields are generated, which then create a magnetic field -- a farily simple electromagnetic. The EXACT mechanics of this are difficult to work out, but has been done.
Yep, the heat is transferred via convection when fluid flow is involved, which is primarily blood flow. For example, you hands are cold, then warm blood flow helps to warm them up. That's convection. Sure conduction is also involved. When heat must pass solid barrier such as cell walls then the heat is transferred via conduction.
