i know density is the molecules in the heat when the molecules are heated they spread apart and rise then over time they cool down and sink when they are cold they come together like when you're cold you want to bundle up to warm up and when you're hot you don't want anyone near because you want to cool off
i don't know about volume but i'm guessing it's how many molecules are in air if there are a lot of molecules in heated air it rises more because the molecules bounce off of each other when there are many molecules in cold air they heat faster because there are more molecules but I don't know
I hope the density part helps
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.
Destiny does not play a role in the process of convection. Convection is a natural process driven by differences in temperature and density that result in the transfer of heat through fluids like air or water. It is based on physical laws and scientific principles, not destiny or fate.
Convection currents are caused by temperature and density differences. As a fluid is heated, it becomes less dense and rises, creating a flow that transfers heat. Conversely, as a fluid cools, it becomes denser and sinks, completing the convection cycle.
Things with a lower density will float on things with a higher density. If you take a fluid (air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated. Get it? Hope you do!
Yes, convection currents in the Earth's mantle connect the poles to the equator. These currents play a crucial role in the movement of tectonic plates, which in turn influences volcanic activity and earthquakes. The heat from the Earth's core is the driving force behind these 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.

In convection less molecules occupy large volume as in air to reduce the density.
because of differences in pressure and density in a fluid

It just happens because of the differenciation in the air density which allows the so called convection currents to occur/form. Complex I know but is the closest conclusion.
A volume of less-than-average density of a liquid will start to rise in the same manner as a balloon. As it rises, volumes of average density flow in below. the surrounding fluid falls to fill the volume left by the fluid flowing in underneath, and, finally the rising volume pushes fluid up and outward. This generates a circular flow which will slow to a stop once equilibrium is reached. If there is a heat source in the fluid it will continually generate lower density fluid, and the convection flow will become continuous.
The three factors that set convection currents in motion are: the heating and cooling of fluid, change in its density, and the force of gravity combine to set it in motion.
