What does the slope of a veloctiy time graphy represent?
The slope represents a change in velocity, or acceleration. The acceleration is the gradient (steepness) of the line. A larger gradient means faster acceleration. if the gradient points down and is negative then it represents deceleration.
Why are winds slowing down?
because of global warming and increase of doldrums.
How does friction between the ground and molecules in the air affect winds near earths surface?
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.
Does barometric pressure go up or down in tornadoes?
Barometric pressure goes down in a tornado.
How does gradient affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
What always occurs down a hydrostatic pressure gradient?
Filtration
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
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.
How does gravity affect the oceans?
Gravity will tend to pull the water down the "hill" or pile of water against the pressure gradient.
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 influences the direction in which the wind moves?
Wind flows from areas of higher pressure to areas of lower pressure. The Coriolis effect influences wind direction by deflecting its path to the right in the Northern hemisphere and to the left in the Southern hemisphere.
What happens to temperature as you go higher in the troposphere?
the temp goes down, the winds go up, and the pressure goes up...
What is the meaning of 'down the concentration'?
Do you mean "down the concentration gradient"?
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
What is moving down the concentration gradient in all cells?
All small molecules can move down the concentration gradient as water O2, CO2 etc.
Where do diffusion molecules move?
Down the concentration gradient
