What causes the pressure gradient force quizlet
Air moving from low pressure to high pressure areas produces pressure gradient force.
How is the pressure gradient force related to wind speed quizlet
In the absence of other forces, the relationship between the pressure gradient force and wind speed is proportional.
How is pressure gradient force related to wind speed
The speed of the wind is directly proportional to the pressure gradient, meaning that as the change in pressure (i.e., pressure gradient increases), the speed of the wind also increases at that location. Pressure gradient is simply the difference in pressure between high- and low-pressure areas.
What is Intrapulmonary pressure quizlet
The pressure inside the pleural cavity is called intrapulmonary pressure.
What causes the Coriolis force quizlet
In the Northern Hemisphere, moving objects tend to curve to the right of their intended paths; in the Southern Hemisphere, moving objects tend to curve to the left of their intended paths. The Coriolis effect tends to increase or decrease the speed of moving objects. The Coriolis effect is brought on by the rotation of the Earth.
What is the main site of gas exchange quizlet
Within the lower airways, specifically the alveoli, gas exchange takes place.
What is the pressure gradient force PGF quizlet
The closer the isobars, the steeper the gradient, the more pgf, and the faster the air moves from high to low due to the pressure gradient force (more dense air to less dense).
What does the movement of air into the lungs depend on quizlet
Airflow and Pressure Differences: For air to enter the lungs, there must be a pressure difference from the outside of the body to the alveoli.
Which law describes the relationship between the pressure and volume of a gas quizlet
The relationship between P (pressure) and V (volume) for gases is described by Boyles Law.
Which of the following pressures rises and falls with the phases of breathing but eventually equalized with the pressure of air in the environment
Intrapulmonary pressure increases when the thorax volume decreases (during exhalation) and decreases when the thorax volume increases (during inhalation), rising and falling with the phases of breathing but eventually equalizing with atmospheric pressure.
How would wind move if Coriolis and friction forces did not exist
Wind would move directly from regions of high atmospheric pressure to regions of low atmospheric pressure if Coriolis and friction forces were absent.
What drives air from areas of higher barometric pressure to areas of lower barometric pressure
The Pressure Gradient Force, which is caused by air moving erratically from areas of high pressure to areas of low pressure, is what propels winds from areas of higher barometric pressure to areas of lower barometric pressure.
What is a typical depth of the friction layer in the atmosphere
Surface friction is effective in slowing wind up to about 1,500 to 3,000 feet above the ground; above this level, air tends to flow parallel to the isobars. The Friction Layer is the lowest layer of the earths atmosphere, typically up to 3,300 feet.
What is the pressure gradient force quizlet
The force that is created when there is a difference in pressure across a surface is known as the pressure gradient force, which is equal to the difference in pressure divided by the distance.
