Which Statement Accurately Describes Why Air Pressure Decreases As Altitude Increases??

Which statement accurately describes why air pressure decreases as altitude increases? As you increase altitude the temperature difference between the layers of the atmosphere causes extreme winds and the air pressure in turn decreases.

Why does air pressure decrease as altitude increase?

At higher elevations there are fewer air molecules above a given surface than a similar surface at lower levels. … Since most of the atmosphere’s molecules are held close to the earth’s surface by the force of gravity air pressure decreases rapidly at first then more slowly at higher levels.

What happens to air pressure as altitude increases increases or decreases?

As altitude rises air pressure drops. In other words if the indicated altitude is high the air pressure is low. This happens for two reasons. … As altitude increases the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.

Which of the following are two reasons why air pressure decreases as altitude increases?

Explaining Changes in Air Pressure with Altitude

There are two reasons why air pressure decreases as altitude increases: density and depth of the atmosphere. Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity so gas particles are denser near the surface.

What happens to air pressure as altitude decreases quizlet?

Describe what happens to air pressure as you rise upwards in the atmosphere. … As altitude increases air pressure will decrease As altitude increases the gas molecules that make up the air spread further apart. Smaller number of particles pushing down on a given area means lower air pressure.

Why is the decrease of air pressure with increasing altitude more rapid when the air is cold?

If a cold air mass is present heights will be lower since cold air is denser than warm air. Denser air takes up a smaller volume thus heights lower toward the surface. Rising air also decreases heights.

Does air pressure increase or decrease with an increase in altitude is the rate of change constant or variable explain?

Air pressure decreases with increase in altitudes. The rate of change varies because pressure decreases rapidly near Earth’s surface and more gradually at greater heights.

Why does atmospheric pressure decrease as you go higher in altitude on Earth quizlet?

Air pressure is strongest near the surface because more air molecules are above you (and pushing on you). As you move higher there is less air molecules pushing on you and therefore as you go up the air pressure decreases.

Why temp decreases with increase in altitude?

As you increase in elevation there is less air above you thus the pressure decreases. As the pressure decreases air molecules spread out further (i.e. air expands) and the temperature decreases.

How does altitude affect air pressure and density?

Air pressure is higher at lower altitudes. Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level.

What general statement can be made about the relationship between air pressure and altitude?

Explanation: The two have an inverse relationship that is when elevation increases atmospheric pressure decreases. This is due to the amount of air on top of you at your current elevation. At lower elevations you have more air above you and thus more pressure.

How does altitude affect tire pressure?

The level of pressure in a tire is created from the relationship between the air in the environment and the air inside the tire. Climbing higher in altitude means the air offer less resistance which creates a higher level of pressure within the tire itself.

Why does pressure decrease nonlinearly with height in the atmosphere?

As the altitude decreases the amount of air molecules found above a given point will be greater and therefore the weight of the air in that column will be greater. … Instead atmospheric pressure decreases more rapidly near the surface than it does at higher altitudes.

How does the air pressure change when the altitude increases quizlet?

How does air pressure change as altitude increases? Air pressure decreases as altitude increases. As air pressure decreases density decreases. … air is very thin.

Does atmospheric pressure increase or decrease as altitude increases neglect changes in temperature?

Atmospheric pressure decreases as altitude increases.

What generally happens to atmospheric pressure with increasing altitude quizlet?

What generally happens to atmospheric pressure with increasing altitude? Atmospheric pressure decreases because the further away you go from Earth and it’s gravitational pull the fewer gas molecules are present in the atmosphere. … Because the density is higher there are more collisions and therefore higher pressures.

What can occur when air rises in a low pressure system?

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure and the air rises in the atmosphere where they meet. As the air rises the water vapor within it condenses forming clouds and often precipitation. … Winds blow away from high pressure.

How is air pressure affected with increase in wind speed?

Answer: When wind speed increases air particles are moving away from a particular place and hence the air pressure decreases.

How much does pressure decrease with altitude?

As elevation increases there is less overlying atmospheric mass so that atmospheric pressure decreases with increasing elevation.

Does air density increase with altitude?

Air density like air pressure decreases with increasing altitude. It also changes with variation in atmospheric pressure temperature and humidity.

What happens to air pressure as altitude increases in the thermosphere?

Thermosphere: As the altitude increases the air temperature increases. Why does air pressure decrease with an increase in altitude? Pressure with Height: pressure decreases with increasing altitude.

What decreases as you go up in the atmosphere quizlet?

Density of the atmosphere decreases as the altitude increases because as you go up you are getting further from the earth.

What happens to atmospheric pressure in the troposphere with increasing altitude?

The upper layers of air push down on the lower layers so that the air pressure near the surface is greater than the air pressure further from the surface. … Therefore air pressure decreases as elevation increases.

When we go to higher altitude then dash decreases?

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations there are fewer air molecules above a given surface than a similar surface at lower levels.

What happened to air pressure when the temperature gets higher?

When gas molecules are heated the molecules move more quickly and the increased velocity causes more collisions. As a result more force is exerted on each molecule and air pressure increases.

When the altitude increases the temperature decreases True or false?

Explanation: Generally temperatures decrease with increasing height because the atmosphere distributes itself according to gravity: Pressure generally decreases with height because the pressure is determined by the mass of the atmosphere above some point.

Why does air pressure decrease as you climb a mountain?

Atmospheric pressure decreases with elevation for a good reason: It’s dependent on the weight of the air above you. If you move higher there is less air above you and thus pressure declines. … Reach 18 000 feet above sea level and pressure drops to about 500 hPa roughly half the pressure measured at sea level.

How does altitude affect air pressure and density check all that apply air is less dense on a mountaintop than at sea level?

Air is less dense on a mountaintop than at sea level. Air pressure is lower at low altitudes. As you climb a mountain air pressure increases. More force pushes on the air at the bottom of an air column.

How does altitude affect air pressure and density check all that apply quizlet?

How does altitude affect air pressure and density? … Air is less dense on a mountaintop than at sea level. More force pushes on the air at the bottom of an air column. As you descend a mountain air molecules are closer together.

Which statement accurately describes the relationship between air pressure air density or altitude as altitude increases pressure increases?

The correct statement is denser exerts more pressure than less dense air. Explanation: this is because with increase in density of there are more molecules of air that are packed within a particular volume of air.

What general statement can be made about the relationship between air pressure and altitude quizlet?

Pressure unlike temperature always decreases with altitude. In the lower layers of the atmosphere pressure decreases much more rapidly than it does at higher altitudes because density decreases as altitude increases.

Which of the following best describes the relationship between altitude and air pressure?

which of the following statements best describes the relationship between atmospheric pressure and altitude? the atmosphere pressure increases as the altitude increases. Much of the life on earth became possible in part because the oxygen levels on earth stay constant.

Does air pressure in tires increase with altitude?

First atmospheric pressure depends on the altitude you are at. The higher you are the smaller the pressure. If you inflate your tyres at 34 psi at sea level pressure inside the tyre will go up along with the rise in altitude.

Does air pressure increase or decrease with altitude in the stratosphere?

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation.
