There is a lot of air above you when you're on the earth's surface, so gravity makes air compress the air you have at sea level.

What place on the earth's surface has the lowest air pressure?
lol
A pump is not used to raise groundwater to the surface in areas where artesian wells are located becasue the water in artesian wells is?
under high pressure
How does wind exist?
Wind exists because of two main forces: The rotation of the earth, and the heat and light from the sun. The rotation of the earth causes wind because the natural tendency of air molecules is to stay still. The earth essentially is moving, and the air is essentially staying where it is, creating the illusion that the air is moving. This is called "the Coriolis Effect". The Coriolis effect is what causes the constant unchanging winds used by sailing ships. The heat from the sun is responsible for almost all of earth's weather, except for those mentioned above. The sun's heat causes the air molecules to become excited, and lack of heat makes the molecules stand still. Excited molecules expand, and create High Pressure. Still molecules contract and create low pressure. When high pressure air moves in to fill in the slight vacuum created by low pressure air, it creates wind. In short HOT AIR = HIGH PRESSURE COLD AIR = LOW PRESSURE HIGH PRESSURE TRIES TO GET TO WHERE THERE IS LESS PRESSURE.
Do hurricanes develop high pressure areas?
Hurricanes are intense low pressure systems.
From what pressure to what pressure does the global wind go?
Wind is created by air pressure, there's a law in meteorology, winds will usually blow from high pressure areas to low pressure areas. That's what this question would be asking for.
Why is air pressure at Earth's surface?
Because it have high dense.
What happens in high pressure?
air molecules are close together and pressure on Earth's surface
Is there high pressure at the surface located within the eye of a hurricane?
No. Pressure in the eye of a hurricane is low.
What happens to the pressure as you move from the center of the earth toward the surface?
Temperature and pressure increase massively from earth's surface to the centre of the Earth. At the inner core, the pressure is so great that iron is solid, even at such high temperatures.
Global winds and pressure systems?
exist at the earth's surface and at high altitudes
Why does magma deep inside the earth rise toward the surface?
because of the high pressure
What happens to the temperature and pressure as you get closer the the earth's core?
Temperature and pressure increase massively from the Earth's surface to the centre of the Earth. At the inner core, the pressure is so great that iron is solid, even at such high temperatures.
How the earth and its magma are formed?
Magma is formed as a result of very high and intense pressure beneath the surface of the earth that leads to the melting of the rock.
What causes a thermal high near the surface?
High pressure at the surface
Is the pressure high at Jupiter's center?
If by 'high' you mean that you would be killed by it then yes. It's a lot higher than on Earth, even at the surface.
How did diamonds arrive on the earths surface?
Diamonds are formed deep within the earth's mantle, under enormous pressure and extreme, high heat. Then, volcanic pipes erupt the diamonds to the earth's surface.
What is the surface pressure if the planet Eris?
The pressure is high
