The weight of the air
The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.
Pressure is caused by collisions of gas molecules with surfaces or other gas molecules.
the collision of molecules (apex)
I have a science test this week and was wondering what causes air pressure differences on our planet?
Earthquakes. Pressure in the Earth's core.
Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.
Driving on low tire pressure flexes the tire, causes overheating and can make the tire come off the rim on corners.
Sometimes inflammation putting pressure on nerves will do this or pressure may be put on the nerves as they pass between the vertebrae in the neck.
causes of abnormal pressure
The force that causes turgor pressure is osmosis.
the force with which what the contract causes blood pressure
It causes blood pressure to increase.
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
heat causes pressure, pressure causes friction, friction causes spark, spark causes KABOOM! all in a split second
Modern lifestyle is full of stress. It causes so because of the pressure. Pressure in lifestyle, Pressure at workplace.
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Low pressure.
Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.
It causes the Bourdon tube to straighten.
