To cause a barometer to rise, high pressure and sinking air must dominate the atmosphere. High pressure occurs when air is sinking and compressing, leading to clear skies and generally fair weather conditions. This sinking air prevents the formation of clouds and causes the barometric pressure to rise.
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
The rise and fall is the tides.
rise
Convection currents cause the air to rise when heated. This causes the air pressure to become lower on the surface, which then pulls in air from nearby regions, which is felt as wind.
It sinks
It would rise
Fuel pumps can produce a pressure drop and rise as variables of voltage and temperature change a dampener absorbs this rise and fall of pressure and keeps the pressure closer to a constant flow for better injector operation.
No. On the moon they just fall. (But it sure would expand !)
the head pressure will rise
It does not rise or fall. It is an imaginary line.
Fall is the height of a slanted or diagonal straight surface. Gradient is the result of rise divided by fall (rise/fall) (rise over fall)

Rain fall tends to occur mostly on hot days because the hot air tends to evaporate and rise. When the water vapor increases, it cool and condenses to form clouds and soon rain.
the tides rise or fall occur every 6hours and 13 minutes because because of the gravitational and rotational force,all particles of the earth ,moon,and the sun attract one another
