This is known as convection.
no
convection current
conduction because it heats everything
Such force is called viscosity..the force produces in liquid and opposes the motion of fluid and also the motion of the objects in fluid..it is also called the internal friction..
Motion of the fluid in pipe is often due to viscosity. When the force action a body moving through the fluid it may be called viscous drag, or just drag.
Convection
The circular motion is called convection current.

The rising and sinking motion is called convection current.
the body motion in fluid is called hydrodynamic drive.
In each of your ears, you have three half-circular tubes with a fluid called endolymph in them. They also contain little hairs (cilia) that can detect the motion of this fluid. Using these, the semicircular canals detect the motion of the head, to help with coordination and balance. When your head moves, the endolymph moves to different sections of the canals, hitting the cilia and sending the signal to the brain. The three canals are oriented in different directions, so the brain can tell which direction you're moving.
When water (or any fluid) is stirred in a circular motion it will form a vortex or vortices. A vortex is a region in which the fluid flows in a circular motion around a vertical axis. Common examples are smoke rings, whirlpools - including those seen behind the oars of boats or hot drinks that have been stirred, water going down a plughole. Often the fluid forms more than one vortex - these are multiple vortices.
