What is the you aided movement of a gas or liquid caused by a pressure difference due to a difference in density within the gas or liquid?
This is known as convection. Convection is the transfer of heat through a fluid (liquid or gas) caused by density differences resulting from temperature variances. Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circular motion that facilitates heat transfer.

What do changes in density cause air movement?
Changes in density cause air movement because air tends to move from areas of higher density to areas of lower density. This movement occurs to equalize the pressure differences caused by the density variations, leading to the flow of air molecules. This process is known as convection.
The movement of material due to differences in density that are caused by differences in temperature is called what?
The movement of material due to differences in density caused by differences in temperature is called convection.
How does density affect doldrums?
Density affects the formation of doldrums by influencing the movement of air masses. In the doldrums, warm, less dense air rises, creating an area of low pressure. This low pressure zone is characterized by calm winds and slow air currents due to the lack of horizontal pressure gradients caused by differences in air density.
Which is caused by density difference?
Buoyancy is primarily caused by density differences. When an object is immersed in a fluid, the upward force it experiences, known as buoyant force, is a result of the density difference between the object and the fluid. Objects with a lower density than the surrounding fluid will float, while those with a higher density will sink.
The movement of material due to differences in density that are caused by differences in temperature is called?
Convection. This process involves the transfer of heat through the movement of a fluid (liquid or gas) driven by variations in temperature and density.
What is the movement of air caused by difference in air pressure is called?
It is called wind.

Local winds can be caused by heating of the Earth's surface?
Yes, local winds are caused by the unequal heating of Earth's surface, which creates variations in air pressure and temperature. This temperature difference leads to the movement of air from areas of high pressure to areas of low pressure, generating local wind patterns.
What is the movement of air caused by differences in air pressure called?
It is called wind.
What is the measurable movement in a vein or artery caused by pressure from heart beat?
N
Where is the movement of air called?
The movement of air is called wind. Wind is caused by the uneven heating of the Earth's surface, leading to variations in air pressure and the subsequent movement of air from high pressure to low pressure areas.
The movement of material due to differences in density that are caused by differences in temperature is called?
Convection. This process involves the transfer of heat through the movement of a fluid (liquid or gas) driven by variations in temperature and density.
Is the buoyant force caused by the increase in density in depth fluid?
Buoyancy is proportional to fluid density but the question seems to imply density increasing with depth. Gases such as the atmosphere behave in that way. Liquids do not because they are to all intents and purposes incompressible. A cubic metre of water in Lake Baikal would still have a mass of 1Tonne whether at the surface or down at the bottom.
