The hotter part of the fluid becomes less dense and rises to the top. Where as the colder part of the fluid will be more dense and will sink to the bottom.
When the density of a fluid gets hotter, it usually decreases. This is because as the fluid gets hotter, its molecules gain energy and move farther apart, causing the fluid to expand. This expansion leads to a decrease in density.
As a fluid gets hotter, its density generally decreases. This is because heat causes the fluid molecules to move faster and spread out, leading to decreased packing and therefore lower density. This relationship is known as thermal expansion.
The density of a fluid goes down (becomes less dense) when heat is applied.
When the density of a fluid increases due to heating, the molecules within the fluid move faster and spread further apart, causing the fluid to expand. This expansion leads to a decrease in density, as the same mass now occupies a larger volume.

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.
When the mantle gets hotter, it becomes more fluid and less viscous, causing it to flow more easily. This increased flow can lead to the movement of tectonic plates and the creation of volcanic activity as magma rises to the surface. Additionally, higher temperatures in the mantle can affect the density of the material and impact convection currents within the Earth's interior.
An object will float in a fluid if its density is less than the fluid's density. If the object's density is greater than the fluid's density, the object will sink. If the object's density is equal to the fluid's density, it will be suspended at a specific depth.
Differences in density create variations in buoyancy in a fluid, which drives the process of convection. When a fluid is heated, it expands and becomes less dense, causing it to rise. Conversely, when a fluid is cooled, it contracts and becomes denser, causing it to sink. This continuous cycle of rising and sinking due to density differences creates the convection currents that lead to heat transfer in fluids.
