Barometric pressure
Atmospheric pressure is the force exerted by the weight of air in the Earth's atmosphere. It is caused by the gravitational pull of the Earth on the air molecules and decreases with altitude.
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.
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.
Barometric pressure
Atmospheric pressure is primarily caused by the weight of air above a specific point on the Earth's surface. Gravity pulls air molecules towards the Earth, creating a force that results in atmospheric pressure.
The weight of air is called atmospheric pressure. It is the force exerted by the weight of the air above a given point in the atmosphere.
Atmospheric pressure is the force exerted by the weight of air in the Earth's atmosphere. It is caused by the gravitational pull of the Earth on the air molecules and decreases with altitude.
Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.
The force exerted by the weight of air is called atmospheric pressure. It is caused by the weight of the air molecules in the Earth's atmosphere pressing down on everything on the Earth's surface. Atmospheric pressure decreases with altitude as there are fewer air molecules above.
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).
The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
The energy source responsible for the motion of molecules in the atmosphere is the pressure caused by the weight of the air. This pressure gradient drives the movement of air molecules from areas of high pressure to areas of low pressure, creating winds and atmospheric circulation patterns.
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.
The downward push of the atmosphere is called atmospheric pressure. It is the force exerted by the weight of air above us and is measured in units such as millibars or inches of mercury.
The weight of air on Earth is called atmospheric pressure. It is the force exerted by the weight of air molecules in the Earth's atmosphere on a surface.
