What is the movement of fluid down a pressure gardient called?
The movement of fluid down a pressure gradient is called flow. It occurs when a fluid moves from an area of high pressure to an area of low pressure in order to equalize the pressure difference.
How does the body establish a pressure gradient for fluid flow?
A pressure gradient exists in the arteries because the heart actively pumps the blood; additionally, the elasticity of the larger arteries helps force the blood along. There is a lower pressure gradient within the veins that is generated by the muscles squeezing the blood along back to the heart (assisted by valves within the veins).
What are the three main driving forces of air motion?
The three main driving forces of air motion are pressure gradient force, Coriolis force, and frictional force. Pressure gradient force is the difference in pressure that causes air to move from high to low pressure areas. Coriolis force is the effect of the Earth's rotation that deflects moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Frictional force slows down the movement of air near the Earth's surface.
The most important forces that affect air motion in the atmosphere are?
The most important forces that affect air motion in the atmosphere are pressure gradient force, Coriolis force, and friction. Pressure gradient force drives air from areas of high pressure to low pressure, Coriolis force deflects air due to the rotation of the Earth, and friction slows down air flow near the Earth's surface.
What factors combine to control wind?
pressure differences, coriolis effect, friction
What always affects the strength and direction of winds?
The primary factors that affect the strength and direction of winds are pressure gradient force, Coriolis effect, friction, and local topography. Pressure gradient force drives air from high to low pressure areas, Coriolis effect influences wind direction due to the Earth's rotation, friction slows down winds near the surface, and local topography can create orographic or valley winds.
What always occurs down a hydrostatic pressure gradient?
Fluid flows from areas of high pressure to areas of low pressure down the hydrostatic pressure gradient. This flow occurs in a continuous manner until pressure equilibrium is reached in the system.
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
How does meandering affect gradient?
Meandering generally results in a decrease in gradient because the river's path lengthens as it winds back and forth. The energy of the flowing water is dissipated as it moves through the meanders, causing the river to slow down and the gradient to decrease.

Why is it more windy at night?
It may seem that winds are stronger at night, but scientifically, days tend to be windier. Nights do seem windy to us because as the world (traffic, people, television, etc) quiets down around us, we begin to hear the wind more. So why are the days windier, then? One thing that causes wind is a pressure gradient, which exists when pressure changes more in one place than in another. This happens mostly in the daytime, when the sun is out and warming different areas differently. After the sun sets, there is less of a chance of such a temperature change. ==In more detail...== In more detailed terms: as a generalization, winds tend to be weakest near dawn and strongest in late afternoon because the colder the ground is, the more of a local inversion you’re likely to have isolating surface winds from the faster winds above (conversely in the late afternoon surface heating allows for more mixing with the faster moving winds above). Winds are not caused by pressure change but by pressure gradient — that is, differences in pressure across space. So heating or cooling can cause winds, but only by changing pressure in one place more than in another, so that a gradient is formed (or strengthened). ==Other causes for wind== There are other wind-causing factors too, however, and these can hit at any time — day or night. For example, winds associated with cyclonic and related frontal circulation are independent of diurnal (daytime/nighttime) factors — you’ll feel those the strongest whenever the associated circulation feature reaches you.
What is unusual pattern occurs during el nino?
The pressure gradient decreases. The trade winds weaken, or even blow backwards.
What is the transport is it when the blood pressure forces some water and solute particles from a blood vessel and into the kidneys?
Filtration is when fluids and solutes flow down their pressure gradient across a membrane such as in the glomerulus of the kidney.
What causes stronger winds to occur?
Stronger winds are typically caused by differences in air pressure. When there is a large contrast in pressure between two areas, air will move from high pressure to low pressure, resulting in strong winds. Other factors like temperature gradients, the Earth's rotation, and topography can also influence wind strength.
What happens to temperature as you go higher in the troposphere?
the temp goes down, the winds go up, and the pressure goes up...
