What is Altitude gauge?

An altitude gauge is an instrument that measures the vertical distance above a reference point, usually in relation to sea level. It is commonly used in aircraft to provide pilots with information about the altitude of the aircraft in flight.


What instrument measures the height of a mountain?

A barometer or a GPS device is commonly used to measure the height of a mountain. Barometric pressure changes with altitude, so by measuring the pressure at the base and summit of a mountain, you can calculate its height. GPS devices can also provide accurate elevation readings.


What instrument measures the altitude of the sun?

An instrument that measures the altitude of the sun is called a sun altitude indicator or a sun sensor. These instruments typically use a combination of sensors, such as inclinometers and light sensors, to determine the angle of the sun relative to the horizon. This information is crucial for various applications, including navigation, astronomy, and solar energy systems.

What is measured by an altimeter?

An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to determine your height above ground.


Is the height of a mountain like Mt Everest always measured from sea level?

The height of a mountain is normally calculated from mean sea level. The height of a mountain above its base is known as its topographical prominence, and the recognized height of Mount Everest was based on this height rather than its height above mean sea level until recently.


What is an instrument for measuring altitude?

A tape measure.


What instrument measures altitude?

An Altimeter---Traditionally, an Altimeter, which works by measuring air pressure. Air pressure decreases as you get higher in a nice reliable linear fashion, so you can use air-pressure to measure altitude. You'll get errors with weather changes, like when that nice low pressure storm front rolls in, your mountain suddenly measures a few meters higher, but its good enough for general use.And to be much more fashionable, you can use a GPS receiver. The Global Positioning System will tell you not only your latitude and longitude, but also your altitude. And its way more accurate than a traditional altimeter.an altimeter


Is the altitude greater at the top of a mountain?

A mountain top is higher (greater) in altitude. That is the definition of altitude : height above a surface, or above sea level.


What instrument is used to measures mass?

This instrument is a balance.


What do we call an instrument which measures heat and cold?

An instrument that measures heat and cold is called a thermometer.


What does the altitude of a mountain mean?

It's the height of the mountain. Or how high up the mountain something/someone is. The peak of Mt Everest is at an altitude of 8 848 meter or so, the altitude of the base camp is around 4000 meters or so.
