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.
What else can I help you with?
Is wind resistance greater near the ground or high in the air?
Wind resistance is typically greater near the ground due to surface friction and obstacles that disrupt airflow. As you move higher in the air, wind resistance decreases because the air is less turbulent and obstacles are less frequent, allowing for smoother flow.
Is the force is greater on a smooth surface or on a rough surface?
The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
How is pressure related to the thrust exerted on a surface?
Pressure is the force exerted per unit area of a surface. The greater the pressure applied on a surface, the greater the thrust exerted on that surface. This relationship is described by the equation: Pressure = Force/Area.
Is the field strength greater closer to the ends of the bar magnet or near the center?
The field strength is greater closer to the ends of the bar magnet than near the center.
Where is the pressure greater . in 10 m below the surface of the sea or 20 m below the surface of the sea?
The pressure is greater at 20 m below the surface of the sea. Pressure increases with depth due to the weight of the water above. Each additional meter of depth adds more pressure, so the pressure will be higher at 20 m compared to 10 m below the surface.
What does airpressure mean?
Air Pressure means the measure of the force with which air molecules pushed on a surface.
Why does venus have a greater gravity pull the earth does?
It hasn't. The acceleration of gravity on or near the surface of Venusis about 91% of what it is on or near the surface of the Earth.(That's less than what it is here.)
Is air pressure greater near the earths surface or at higher altitudes?
I am sure that if you think about the problems encountered by climbers on Mount Everest you might be able to answer that yourself. Near the Earth's surface.

What measures airpressure?
it is a barometer
Why does a dam at the end of a lake need to be wider at the bottom?
Because water pressure is greater near the surface of the water
What is the most likely that there is more oxygen in water near the surface?
Near the surface of water, oxygen levels are higher due to aeration from the atmosphere and photosynthesis by aquatic plants. This results in greater oxygen saturation near the surface compared to deeper levels where oxygen may be consumed by decaying organic matter.
Is it true seismic waves of an earthquake are greater closer to the surface of the crust near a city?
No, the location of a city is unknown by and irrelevant to the earthquake.
What are lines on a maps that join places that have the same airpressure?
isobars
Where is the change in length of daytime greater near equator or near the poles?
The closer you are to the poles, the greater the change.
Is Saturn's gravity stronger or weaker than earth's gravity?
The acceleration of gravity, and therefore the weight of an object located there, at the place where Saturn's surface would be if it had one, is 13.91% greater than it is on or near the Earth's surface.
