Air weight that varies over earths surface is called?
Atmospheric pressure varies over Earth's surface, mainly due to differences in temperature, altitude, and weather conditions. This variation in air pressure creates different weight of air known as atmospheric weight.
Is air pressure weak or strong at earths surface?
weak and strong,it depends
Which direction does the air currents towards the poles or away from the poles?
Away from the poles because the air near Earths surface is warm.
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.

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 causes air to move with the earths surface?
convection
Where is the highest air pressure?
air pressure is the highest near the earths surface
Why is high air pressure near earths surface?
Because there is more air (which has weight) above you if you are around sea level. If you fly up, or climb a mountain, there is less air above you, therefore less air pressure.
About how much is the Moon's gravitational force compares to the earths?
The weight of any object on the surface of the moon is 16.55% of its weight on the surface of the Earth.
What happens to air pressure as you move away from earths surface?
Air pressure decreases as you move away from Earth's surface. This is because the weight of air above you becomes less as you move higher in the atmosphere, resulting in lower air pressure at higher altitudes.
What is horizontal movement of air in realtion to the earths surface?
updraught
What causes air to be denser near earths surface?
Air near Earth's surface is denser due to the weight of the air above it pressing down, creating higher pressure. Additionally, higher temperatures near the surface cause air molecules to move more rapidly, spreading out less and increasing air density.
Why is there so much more pressure exerted on the earths core than the earths surface?
Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
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.
Why is air preassuare greastest at the earths surface?
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
