Thermal expansion causes the fluid to become less dense. It rises as a result and other fluid sinks to take its place.

Fluids rise and sink in a convection current due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, creating an upward flow. As it cools, it becomes more dense and sinks, creating a downward flow. This continuous cycle of heating and cooling drives the convection current.

Does a jet stream or convection current cause gases and liquids to rise and sink in a circular path?
Convection current
When gases or liquids rise and sink in a circular path?
Convection current
What can carry heat by convection?
Convection is when fluids (yes, air is considered a fluid) mix... Hot (less dense) molecules will rise as opposed to cold (more dense) molecules will sink.
Why does the heat rise in convection?
There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.
What is the similarities and differences between conduction and convection?
Both conduction and convection are types of heat transfer, meaning they move heat from one object to another. The difference is how they transfer the heat. Conduction transfers heat from touching solid to touching solid, while convection transfers heat in fluids (liquid or a gas).Convection transfers heat by having the warm types of fluid rise while the cold sinks. This creates something called a convection current.
What is it called when lighter, warmer fluids rise to the top while denser, cooler fluids sink?

What is Convection Currents?
Convection current is the flow of hot fluid in a circular pattern. A convection current is a form of transfer of energy. It occurs mainly in liquids, but it can also occur in gases. In a convection current, the particles with greater energy (the particles that are hotter) rise because they become less dense. As they rise, particles with less energy (cooler particles) rush in to replace the particles that rose as they are more dense. You can see this happening with sea and land breezes.
Is there warmer air in a convection current?
A convection current in air will have warmer air near to the heat source and this will rise. Then it gradually loses heat to the surroundings and sinks again, so there is warmer air in parts of the current and cooler air in other parts.
Energy is usually transferred in fluids by radiation?
No, the principle method of heat transfer in fluids is convection, as the most energetic molecules rise towards the surface and the least energetic sink. Radiation is most significant for objects which are very hot, even glowing.
What is a example of convection?
hot air ballon because since the air is heated in the hot air balloon it will rise, And water boiling in a pan if you were cooking pasta you can see the pasta rise and fall with the convection current in the boiling water
What chemicals from the periodic table make a hot air balloon rise?
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
