The transition altitude in the United States is typically 18,000 feet above mean sea level. This is the altitude at which aircraft transition from using the altimeter setting in inches of mercury to a standard setting of 29.92 inches of mercury.
A not-commonly-used measurement is 'atmosphere'. One atmosphere is the average pressure at sea-level: 101.325 kPa, 1013.25 mbar, 29.921 inches of mercury (inHg) or 760 millimeters of mercury (mmHg).
When a thermometer bulb containing mercury is placed in hot water, the mercury inside expands, causing the level of mercury to rise. This expansion of mercury is used to measure the increase in temperature accurately.
Barometric pressure at ground level refers to the atmospheric pressure at the Earth's surface. It is commonly measured in units of millibars or inches of mercury and can vary due to weather conditions, altitude, and geographic location. Changes in barometric pressure can indicate approaching weather systems and have effects on human health and behavior.
It is called altitude. It is typically expressed as ASL (above mean sea level, or MSL). However, it can also be specified as AGL (Above the local Ground Level).
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.

The mercury level rises in a thermometer when the temperature increases because heat causes the mercury to expand, pushing it up the tube. Conversely, the mercury level falls when the temperature decreases because the cooler temperature causes the mercury to contract, moving it down the tube.
The diference is simple, the transition altitude is the altitude above sea level at wich the aircraft change from the use of altitude to the use of flight level. When operating above the transition altitude, the aircraft altimeters pressure seting is normally adjusted to the standard pressure setting wich is 1013 millibars in europe, or 29.92 inches of mercury in US, or Canada. There the aircraft altitude will be expressed as a flight level.
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
Altitude describes an object's position relative to sea level. An object in a position higher than sea level would have a positive altitude, sea level would have an altitude of zero, and any object below sea level would have a negative altitude.

their red blood cell count...high altitude=low o2 level
Yes, the level of acid rain can increase. As acid rain falls on objects that have already been hit with acid rain, the acid builds up and becomes stronger.
