What is the answer of...Air particles pressing down on a surface?
Wiki User
∙ 14y ago
Air pressure.
At sea level it is approximately 760 mmHg.
I say approximately because air pressure naturally changes between high pressure areas(anticyclones) and low pressure areas (depressions/cyclones/hurricanes/typhoons).
NB 760 mmHg means that the air pressure will support a column of Mercury(Hg - hydragyrum) of approximate height 760 mm (millimetres) ( 0.76 metres).
Sometimes air pressure is measured in 'pounds per square inches' or 'pascals'.

What causes rocks to become round and smooth?
Weathering and erosion. Weathering causes rock to break into smaller particles. When these particles are transported by wind, water, or ice, the jagged edges from fracture are gradually worn down from abrasion with other particles, making the outer surface appear relatively smooth. Sometimes the mere abrasive effects of windblown particles on a rock will smooth the exposed surface, leaving the remainder of the rock jagged.
Does the pressure in the atmosphere increase or decrease?
Going farther up into air, pressure decreases. Going down, pressure increases. When you think about it, more air is pressing down on you when you are standing on earth because more is on top of you. When you are up in the air, there isn't as much air pressing on you which shows that there isn't as much pressure. The same concept applies when under water; The farther you go under, more water is pressing on you than when you are more towards the surface which=more pressure (underwater).
Why is air pressure greatest at the Earth's surface?
Because as you get closer to the surface of the earth, the more air that is on top of you. At the top of the atmosphere, there is no air, and everything is a vacuum, where you have no weight. When you get close to the earth, the weight of the air builds until it when you're at the very lowest point of the earths surface, all the air in the atmosphere above you is pressing down.
How does soil evolve?
Soil forms as rock is broken down by weathering and mixes with other materials on the surface. Soil is a mixture of rock particles, minerals, decayed organic material, air, and water.
When region of earth's surface sink down?
when regions of earth surface sink down
Why would the pressure decrease from the core to the crust of Earth?
There is less weight pressing down from above as the distance toward the surface decreases.
Could decreasing the surface area increase the rate of a reaction?
Not really... it surely would slow it down as there is less surface area for particles to collide with.
Do you experience more pressure when you swim on the surface?
No. You experience greater and greater pressure as you swim farther and farther below the surface of the water. This is because there is a greater height of water pressing down on you from above.
How do particles move in a surface wave?
Surface Waves can propagate only along the boundary of solid.Two types are:Rayliegh Waves propagate along boundary between two dissimilar solid media, in a plane perpendicular to the surface and containing the direction of propagation.Love Waves are polarized shear wave with an associated oscillatory particle motion parallel to the free space and perpendicular to the direction wave motion.
What is a barometer used to measure?
the weight of the air pressing down on the earths surface is known as air pressure.this pressure is measured using a barometer
What is the air pressure of the moon?
I would imagine it drops, because there is less gravity.
What is molecules closer to the surface that are more densely packed than those higher in the atmosphere because of gases pressing down from higher in the atmosphere?
Atmospheric pressure
Can Ultrasound produce coagulation in liquid?
It may do in certain materials at appropriate frequencies but usually it breaks particles or surface-films down.
Why does an object moving through the air slow down?
=normally objects slow down because of the friction. this means that the surface area is in contact with the air particles so that will slow the object down.==or they put the breaks on .=
What is the transpiration process?
Transpiration is the evaporation of water from the surface of the plant__mainly from leaves. Water particles evaporate from the surface of the leaves, and more water particles move up within the plant to take their place. This process continues down though the plant with particles continually moving up from the roots.The loss of water in plants to the air though the stomata of plant leaves.

How does the mechanical digestin change the surface area of food?
Breaking down of large macromolecules to monomers is known as catabolism. More the substance is broken down, larger its surface area gets. A particle with more surface area can be easily be metabolized by our body. Enzymes can act with full tendency on particles that have larger surface area and then an be easily digested and absorbed by out boy.
