Why is airpressure greater near the surface?
Air pressure is greater near the surface because air has mass, which means that the mass of the Earth causes the force of gravity to pull the air towards the surface. This causes the air molecules to compress, which increases air pressure. At the same time, the air molecules want to depressurize, because they are a gas, causing them to physically push on each other. This causes the air pressure closest to the surface to be highest, because the depth of the air above those closest to the surface is greatest. As altitude increases, air pressure decreases for the same reason - there is less mass pushing from above.
How much is 1kN in tonnes?
Kilonewtons measure force, tonnes measure mass so strictly speaking they cannot be compared. However we can say that 1 kN is the force the between the Earth (at its surface) and a mass of 0.102 tonnes.
Is weight a measure of earth's pull of gravity?
Weight is what we call the amount of the gravitational force between the Earth and an object on the surface of the Earth. It works both ways. Your weight on the Earth is also the Earth's weight on you.
1Newton in kgs?
A Newton (or a Kilonewton) is a measure of FORCE, not of weight. On Earth's surface, a mass of 1 kg exerts a force of approximately 9.8 N [down]
How do you measure mass of objects?
mass = weight ÷ gravity Since the gravitational pull is relatively constant near the surface of the earth, you can weigh the object, then divide the weight by the gravitational acceleration (9.8 m/sec2 near the earth's surface).
What is the measure of the force with which air molecules are pushing on the Earth's surface?
Air Pressure
What is the measure of the force with which air molecules are pushing on the earth surface?
Air Pressure
The measure of the force with which air molecules are pushing on the Earth's surface?
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
The force with which air pushes on the earth's surface is called?
The measure of force with which air molecules are pushing on earths surface is called air pressure. At sea level, at what we call standard atmospheric pressure, the pressure is about 14.696 PSI, or about 29.92 inHg, or about 760 mmHg. This is 101.324
Why is atmospheric pressure greatest at the surface of earth?
Atmospheric pressure is greatest at the surface of the Earth because there is more air above pushing down. As you move higher in the atmosphere, there is less air above, resulting in lower atmospheric pressure. Gravity also plays a role in compressing the air molecules closer to the Earth's surface, increasing the pressure.
How can stone mountain change the Earth's surface?
it changes the earths surface by...pushing in to the earth!falling down and crumbling the earth!and being the largest rock in the world it creates attraction!
Does the surface wave magnitude or M's measure the movement of seismic waves underneath the Earth's surface?
No, P-waves and S-waves are used to measure seismic events under the Earth's surface.
Why does pressure decrease but temperature varies as altitude increases?
there is less oxygen and the molecules are more spread out
A measure of height above earth's surface is called?
altitude
How does friction between the ground and molecules in the air affects winds near the earth surface?
upper earth (atmosphere)For computer answer A+ air near the earth's surface blows more slowly.
What happens in high pressure?
air molecules are close together and pressure on Earth's surface
Where do fossil rocks are most form?
Under the earth surface when dirt is compacted and it is pushing against something hard...
