arterial pressure
An area of high pressure where the air moves apart and sinks is an anticyclone.
As air sinks, it experiences higher pressure due to the increasing weight of the air column above it. This is because air pressure increases with depth in the atmosphere.
I consider them average.
it is because air sinks at the poles
Air rises in a low pressure area and sinks in a high pressure area.
Pressure plays a role in determining whether an object floats or sinks by affecting the buoyant force acting on the object. If the pressure on an object is greater than the buoyant force, the object will sink. Conversely, if the pressure is less than the buoyant force, the object will float.
The source region in the pressure flow explanation of phloem transport is typically the sugar-producing tissues like leaves where sugar is actively loaded into the phloem. This creates a high concentration of sugars in the phloem sap, generating a pressure gradient that drives the flow of sap towards sinks such as growing regions or storage tissues.
it builds up air pressure and sucking
The air in a high pressure area sinks due to the increased weight of the atmosphere pressing down on it. This sinking motion creates stable weather conditions with generally clear skies.
No. When air sinks in a high pressure system it is compressed and warms up. This tends to cause clouds to evaporate and inhibits convection, thus making rain less likely.
Phloem ~ Pressure Flow Theory The phloem tissue moves products of photosynthesis by active transport. The flow of materials in phloem is an active process that requires energy. The mechanism of flow is driven by an osmotic pressure gradient, generated by difference in sugar and water concentrations. Just remember photosynthesis= water + sugar water= osmosis sugar=gradient
The cold and dense air at the poles sinks towards the surface. This creates a high-pressure system that can lead to cold and stable weather conditions.
