Convection
It is because the heat is driven out of your hand. That's the simplest I can put it.
Convection is when water warms and expands. As the heated water expands, it rises because when a substance is hotter, it is also less dense. When the hotter and lighter water rises and reaches its maximum height, it is the farthest away from its heat source. It is then cooled and becomes more dense, sinking back down towards it's original location. It is usually related to liquids.
Convection is the mode of heat transfer, referring to the transfer of heat energy due to bulk motion of a fluid."Convection current" is the name of that bulk motion of the fluid, the transfer of MASS. I prefer to call it buoyantly driven flow. It doesn't flow due to convection, convection is due to if flowing. It flows due to buoyancy in the case of free convection.Peyton
Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
There are many different ways to use radiant energy to heat your home including radiant flooring, radiant electric heating, radiant tiles... The site in the related links has tons of information on radiant heating. Technically, "radiant" heating is used to distinguish from "forced air" systems. In a radiant system the radiant elements emit heat and in an forced-air system the furnace heats air, which is then moved to where the heat is needed. A radiant system can be electrical, hyrdonic or steam-driven. For instance, a hydronic boiler heats water to about 180 degrees and uses circulators (forced hot water) to move the heated water to a finned-tube, floor-tubing, wall-tubing, or cast-iron radiator, heating the radiator, radiating heat into the room. The cooled water then flows back to the boiler to be heated again.
The engine that drives atmospheric circulation is the sun - which provides the energy for the circulation.
As thunderstorms are transient atmospheric phenomena, they can occure anywhere in Britain driven by the prevaling atmospheic circulation.
The thermohaline circulation is driven by surface heat (insolaration) and freshwater flows. These change the density of the ocean's water and gravity does the work.

Thermohaline circulation is also called overturning circulation. It is driven by density. The time scale for thermohaine is 1000 years.
Gravity driven circulation
That can be said about basically any process.
