Convection is the movement caused within a fluid by "warm currents". The hotter fluid will rise, pushing the cooler fluid down, which then in turn gets heated, creating a continuous cycle.
Convection is transferred by the larger-scale motion of currents in the fluid.
No, it is not true that heat transfer by the movement of currents within a fluid is called density; it is actually called convection. Density is something else entirely, it refers to weight per a given volume. Of course, density is relevant to convection. Heat causes fluids to expand and therefore to become less dense, and therefore to rise.
Convection
true
Not unless the fluid is flowing due to temperature/density differences.
Convection currents.

The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.

If it is a result of temperature differences, it is called convection.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid

As the fluid warms:The currents speed upThen as the temperatures of the fluid equalise (the fluid becomes one temp) the currents slow downWhen the fluid is one temperature the currents stop
