How would a barometer change if you traveled deep under the earth in a mineshaft?
What changes in air pressure would you expect to see if you carried a barometer down a mine shaft? Explain. The air pressure would go up because as you go down further the pressure goes up.
What happens when barometer goes down?
In general, a falling barometer means worsening weather. When atmospheric pressure drops suddenly, this usually indicates that a storm is on its way. When atmospheric pressure remains steady, there will likely be no immediate change in the weather.
How is the reading of barometer affected when it is taken to a mine?
(a) When a barometer is taken to a mine, it’s reading increases because the atmospheric pressure increases with depth.
What happens to the air pressure if you go down a deep mine?
Geologists calculate that, for every mile you dig beneath the Earth’s surface, the temperature rises 15º F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch.
What would happen to the reading of a barometer if it was brought up a mountain from sea level?
Atmospheric Pressure and Altitude At sea level, a mercury column will rise a distance of 760 mm. If we climb to the top of Mount Everest (the highest mountain in the world at 29,029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).
How does elevation affect barometric pressure?
In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation.
How does barometric pressure affect humans?
Some people may be more sensitive to weather changes experiencing more stiffness, pain, and swelling with a barometric pressure decline. Scientists suggest that a fall in air pressure allows the tissues (including muscles and tendons) to swell or expand.
How is the reading of barometer affected when it is taken to 1 A mine and 2 a hill give reasons?
(i) In a mine, reading of a barometer increases. (ii) On hills, reading of barometer decreases.
How is the reading of a barometer affected when it is taken to a a mine and B a hill explain with reason?
The reading of a barometer decreases, due to a decrease in height of the atmosphere above it. The reading of the barometer would go down as the altitude increases because the higher the altitude the less atmospheric pressure.
What changes in air pressure would you expect if you carried a barometer down a mine shaft?
If you carried a barometer down a mine shaft the air pressure would increase. The amount of air above you would increase as you go downward, thus increasing the “weight”, or pressure, of the air above you.
How Does height affect air pressure?
As altitude rises, air pressure drops. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by “thin air.” Thin air exerts less pressure than air at a lower altitude.
