Convection
Convection is where warm air rises and cold air sinks!
Convection
What it does and how it works
Conduction, convection, and radiation
Convection
Convection is the name for a means of heat transfer, as distinguished from conduction and radiation. It is also a term that describes processes affecting the atmosphere, waters, and solid earth. In the atmosphere, hot air rises on convection currents, circulating and creating clouds and winds. Likewise, convection in the hydrosphere circulates water, keeping the temperature gradients of the oceans stable. The term convection generally refers to the movement of fluids, meaning liquids and gases, but in the earth sciences, convection also can be used to describe processes that occur in the solid earth. This geologic convection, as it is known, drives the plate movement that is one of the key aspects of plate tectonics.
Radiation
Everyone is aware of our environment. We are aware of our physical surroundings, buildings, vehicles, streets, sky, weather. Our five senses are well adapted to our basic needs. Sight, smell, taste, sound, feeling are all senses that can help us adapt to and even alter our environment. We feel hot, we turn on the air conditioning.
Conduction
Well, heat is transferred in several different ways: conduction, convection, and radiation. Regardless of the method of transfer, only heat can be transferred because cold is the absence of heat. Conduction is the transfer of heat from one molecule to another through a substance. Not all substances conduct heat at the same speed.
