Why is the atmospheric pressure at the top of mt Everest 5 lbin squared much less than the atmospheric pressure here on earth 14.7 lbin squared?
The atmospheric pressure is caused by the weight of the air on top of us. At the top of mount Everest, there is less air above the exhausted climber (because a lot of the air is below). Less air, less weight, less pressure.
What factor is most responsible for Earth's atmospheric pressure?
The atmospheric pressure on Earth is primarily caused by the weight of the air above us. Gravity pulls the air downward, creating pressure at the Earth's surface. The mass and density of the air also play a role in determining atmospheric pressure.
Why does air exert pressure?
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
What cause air pressure?
Air pressure is caused by the weight of the air above us pressing down on the air below. This pressure is a result of Earth's gravity pulling the air molecules towards the surface. Temperature changes and weather systems can also affect air pressure.
What produces air pressure at the surface of the earth?
Air pressure is the force exerted by the gases in the atmosphere as Earth's gravity pulls on it. The atmosphere can be thought of as a 'sea' of gas surrounding the planet. Air pushes against us from all directions as the weight of air above compresses the air below (this is why altitude affects air pressure.)
What is the force of the atmosphere pushing down on us?
The force of the atmosphere pushing down on us is called atmospheric pressure. This pressure is caused by the weight of the air above us pressing down on the Earth's surface. On average, the atmospheric pressure at sea level is about 14.7 pounds per square inch (psi).
What is the force of air pushing down on us?
The force of air pushing down on us is due to atmospheric pressure. At sea level, this pressure is about 14.7 pounds per square inch (psi). This pressure decreases with increasing altitude.
Why doesn't out body get crushed due to atmospheric pressure around us?
The atmospheric pressure will not crush us because there is a balanced force around us. The contents of our bodies are pushing out as much as the air is pushing in. In fact, it used to be thought that you would explode if you were exposed to a vacuum, though this is now thought to be wrong (It would be awful, but your skin is very stretchy). You can work out the pressure with the equation: PRESSURE= FORCE x AREA.
If gravity is pulling you what is pushing you back?
Nothing. Actually gravity is pushing you down but there is enough air resistance on the earth to stop us feeling heavy and crushed
Why does the atmospheric pressure around us not crush us?
Our bodies are constantly under pressure from the atmosphere, but our internal pressure matches the external pressure, so there is no net force pushing on us. Additionally, our bodies contain fluids and structures that help distribute and balance the forces acting on us, preventing us from being crushed by the atmospheric pressure. The pressure inside our bodies is equal to the pressure outside, keeping us in equilibrium.
How much air pressure is exerted on us?
The average air pressure at sea level is about 14.7 pounds per square inch (psi), or 101.3 kilopascals. This pressure is caused by the weight of the air in the Earth's atmosphere above us. It decreases as altitude increases.
How does wind effect earth and people?
wind effects the earth and people by giving us signs to high pressure and low pressure
Why do way less on the moon?
There are two reasons we way less on the moon; 1.)Since there is not much of an atmosphere up there, there are not hundreds of pounds pushing down on us. 2.)Another reason is since earth is bigger than the moon, Earth pulls us towards itself much more than a smaller object such as the moon would
Why is the atmospheric pressure at the top of mt Everest 5 lbin squared much less than the atmospheric pressure here on earth 14.7 lbin squared?
The atmospheric pressure is caused by the weight of the air on top of us. At the top of mount Everest, there is less air above the exhausted climber (because a lot of the air is below). Less air, less weight, less pressure.
Explain why we do not sink into the earth although gravity is pushing us down?
We do not sink into the Earth because the ground beneath us exerts an equal and opposite force, called the normal force, that counteracts gravity. This balance of forces keeps us from sinking further into the Earth's surface.
Why does air pressure happen?
Air pressure is a product of the operation of gravity on the mass of atmospheric air. If there were insufficient or no gravity on Earth, the atmosphere would drift off into space. There would be no air pressure. But, because there IS gravity on Earth, the atmosphere presses down on Earth's surface, resulting in the phenomenon known as air pressure.
What theories are keeping us from going deeper into the Earth?
Because, the conditions going closer to the Earth is too hot for a human to handle. Also, there is too much pressure when you go lower to the Earth's interior. ~HOPE THIS HELPS :D
