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.
What else can I help you with?
Where is the highest air pressure?
air pressure is the highest near the earths surface
The atmospheric pressure near the earths surface does what?
It decreases as you move away from the earth surface
What causes a thermal high near the surface?
High pressure at the surface
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 happens when the atmospheric pressure is greatest near the Earths surface?
When atmospheric pressure is greatest near the Earth's surface, it usually indicates stable and fair weather conditions. High pressure systems generally bring clear skies, low humidity, and light winds. This can lead to pleasant weather conditions in the area.
Why do clouds usually form high in the air instead near the earths surface?
Because there is more water vapor up in the sky.
Igneous rocks formed on or near Earth's surface?
extrusive because it forms on or near earths surface
What igneous rocks formed or on or near earths surface?
Volcanoes.
Why is the sun's energy generated mostly at its center and not near its surface?
At the center, both the temperature and the pressure are highest. Both a high pressure and a high temperature increase the likelihood of fusion.
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.
How does friction between the ground and molecules in the air affect winds near the earhts surface?
Friction between the ground and air molecules slows down the movement of air near the Earth's surface, creating areas of high pressure. This can cause surface winds to flow from areas of high pressure to low pressure, resulting in the formation of wind patterns.
