What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
What is the change in pressure measured across a given distance called?
Pressure gradient A+LS
Where on a weather map wind speeds are related to?
On a weather map, the lines of equal pressure (isobars) also illustrate the pressure gradient or change of pressure per distance. The higher the pressure gradient, the higher the winds speed. Thus, when the isobars are close together, the gradient is high, and winds are higher than where the isobars are further apart. Wind can also be affected by local considerations, hills, valleys, and buildings can modify the gradient wind's direction and speed.
How will the pressure of an object change if its area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
How does atmospheric pressure change as you move away from the surface of earth?
Air pressure decreases as you move away from Earth's surface.
What do you call the rate at which air pressure changes between high and low pressure areas?
The pressure gradient, which would be expressed as some unit of pressure change (usually millibars but sometimes inches of mercury) per some unit of distance (usually kilometer).The pressure gradient is roughly proportional to wind speed, so sharper pressure gradients mean stronger winds.

It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.

What are Isobars and what does it mean when they are close together?
It means that there is a steep gradient, or pressure change, and strong winds.
What is the temperature gradient formula?
Gradient= Change in field value/Distance
How does pressure change as you go from the surface toward the center if the earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
