The weather changes in relation to the air pressure. Air molecules always travel towards low pressure where there is less force acting on them. This has an effect on the weather. Generally, high pressure means good weather and low pressure means bad weather. Barometers measure the pressure, often in Hectopascals.

Why air pressure is a really useful thing to measure?

I believe air pressure is measured in PSI ( pound per square inch) by using a barometer


How does the pressure at the bottom of a 76 cm column of mercury in a barometer compare with air pressure at the bottom of the atmosphere?

The pressure at the bottom of a 76 cm column of mercury in a barometer would be equal to the atmospheric pressure pushing down on the mercury column. This is because the height of the mercury column in a barometer is directly related to the atmospheric pressure. Thus, the pressure at the bottom of the mercury column would be the same as the air pressure at the bottom of the atmosphere.


How is plate tectonics related to Natural Hazards?

Plate tectonics is related to natural hazards because the movement of tectonic plates can cause earthquakes, volcanic eruptions, and tsunamis. These events can lead to significant damage to infrastructure, loss of life, and environmental impacts. Understanding plate tectonics helps predict and mitigate the risks associated with these natural hazards.


Which instrument does not belong in this group anemometer barometer thermometer and seismograph?

The instrument that does not belong in this group is the seismograph. An anemometer, barometer, and thermometer are all instruments used to measure weather-related phenomena such as wind speed, air pressure, and temperature, respectively. A seismograph, on the other hand, is used to measure and record seismic waves caused by earthquakes.


Why is meterology important?

Meteorology is important because it helps us understand and predict weather patterns, which is crucial for making informed decisions to protect lives and property. It also plays a key role in sectors like agriculture, transportation, and energy by providing valuable information for planning and managing weather-related risks. Additionally, meteorology contributes to scientific research on climate change and its impacts on our planet.

Is an application of technology which enhances human ability to predict weather changes?

Weather forecasting technology, such as supercomputers and satellites, can enhance our ability to predict weather changes by collecting and analyzing large amounts of data in real-time. This technology enables meteorologists to make more accurate and timely weather predictions, helping to warn and prepare people for potential weather-related hazards.


How does a barometer help meteorologist?

In meteorology, the baromatic pressures shown are reduced to sea level, not the surface pressures at the map locations. The distribution of isobars is closely related to the magnitude and direction of the wind field, and can be used to predict future weather patterns.


Are barometers related to math Actually me in class 6 and have a math project on how math is used in daily life i thought a barometer would do. any ideas and is a barometer realted to math?

No! Barometers are not related to maths. They are devices used to measure atmospheric pressure... You may not be able to use barometers for maths project. - Abid


How can physical geography help people adjust to the dangers of the people?

It can help because it can predict ocean rises because of polar melting forestal fires, earthquakes, and huricanes sin it studies climate, geology, and everithing related to our phisical world it can also predict a massive animal migration descompensating the food chain.

Who discovered mercury barometer?

The mercury barometer was invented by Italian scientist Evangelista Torricelli in 1643. Torricelli's innovation allowed for accurate measurement of atmospheric pressure using mercury as the working fluid in a glass tube.
