What happens to air pressure as the distance from Earths surface increases?
As the distance from Earth's surface increases, the air pressure decreases. This is because there is less air above pushing down on the air below. The decrease in air pressure is why it becomes harder to breathe at higher altitudes.
Is the force of the water on the piers the same at the water surface as it is m below the surface?
No, the force of the water on the piers increases with depth below the surface due to the increasing pressure from the weight of water above. This is described by Pascal's law, which states that pressure in a fluid increases with depth.
What is the relationship between the density of earth materials and depth below the surface of the earth?
The density of Earth materials generally increases with depth below the surface due to the increasing pressure from the overlying layers. As depth increases, the materials experience more compression, leading to higher densities. The variation in density with depth is important for understanding the structure and composition of the Earth's interior.
Is the force of the water on the piers the same at the water surface as it is 30m below the surface?
No, it would be less due to compression by weight of the surface area water. Every so many feet (meters) down, another "atmosphere" of pressure is exerted. Ergo, water at the seabed would exert more pressure on the pier than the water at the surface.
What kind of pressure does a column of air exert on the air or surface below it?
A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
What happens to air pressure as the distance from Earths surface increases?
As the distance from Earth's surface increases, the air pressure decreases. This is because there is less air above pushing down on the air below. The decrease in air pressure is why it becomes harder to breathe at higher altitudes.
What happens to temperature as depth below earth surface increases?
It increases up to a certain point.
Does pressure and temperature increase or decrease with depth below earths surface?
it increases
Where the pressure is greater 10m above the surface of the sea 20m below the surface of the sea?
Pressure increases the deeper you sink beneath the surface of the sea. So 20 metres below the surface has more pressure than 10 metres above the surface.
Where is the pressure greater . in 10 m below the surface of the sea or 20 m below the surface of the sea?
The pressure is greater at 20 m below the surface of the sea. Pressure increases with depth due to the weight of the water above. Each additional meter of depth adds more pressure, so the pressure will be higher at 20 m compared to 10 m below the surface.
Is the force of the water on the piers the same at the water surface as it is m below the surface?
No, the force of the water on the piers increases with depth below the surface due to the increasing pressure from the weight of water above. This is described by Pascal's law, which states that pressure in a fluid increases with depth.
What describes how temperature and pressure change with depth below Earth's surface?
Both temperature and pressure increase with depth.
How does pressure change as the depth below the surface of a fluid increase?
Pressure increases with depth below the surface of a fluid due to the weight of the fluid above pushing down. This relationship is described by the hydrostatic pressure formula P = ρgh, where P is pressure, ρ is density, g is acceleration due to gravity, and h is depth.
What increases the pressure of a gas below?
air
What is the relationship between weight and pressure?
Pressure varies with height as a function of specific weight. p=p0+specific weight*height Where height is the distance below the reference pressure p0 (usually at a free surface).
What is the pressure in atmospheres on the body of a diver if he is 21 ft below the surface when the atmospheric pressure at the surface is 0.94 atm?
The pressure of freshwater increases by 1 atm for each 34 ft of depth. The pressure of seawater increases by 1 atm for each 33 ft of depth. If surface pressure is 0.97 atm, simply add that pressure to the pressure of the water. For seawater, you are exactly 1 atm below the surface... So: 1 atm + 0.97 atm = 1.97 atm For freshwater, divide 33 by 34 to get the fraction of an atmosphere you're adding to your surface pressure: 33/34 * 1 = 0.97 atm Then add that number to the surface pressure: 0.97 + 0.97 = 0.94 atm
What is the pressure at the 500 m below the seawater surface?
Every 10 meters you go down, the pressure increases by about 1 bar. You must also consider the air pressure, which is about 1 bar. You can base your calculations on that.
