Science Final 6 Air Pressure/Air Masses

Air pressure moves from

As altitude increases, air pressure

• Increases
• Remains constant
• Decreases
• Fluctuates

As density increases, air pressure

• decreases
• remains constant
• doubles
• increases

Is air pressure greater at the top of a mountain or in a valley?

Where is air pressure less at the top of a mountain or in a valley?

Does air have mass?

• Yes
• Rarely
• Sometimes
• No

What is altitude?

• Distance above sea level.

• Altitude is the distance between two points on the Earth's surface.
• Altitude is the temperature at which water boils.
• Altitude is the speed of an object in motion.

What is gravity?

• Gravity is a form of light
• Gravity is a type of energy
• Gravity is a type of sound
• Gravity is a force that attracts objects with mass towards each other.

What is air pressure?

• The result of weight of a column of air pushing down on an area

• Air pressure is the force exerted by the weight of objects in the atmosphere
• Air pressure is the force exerted by the weight of water vapor in the air
• Air pressure is the force exerted by the wind on a surface

What is density?

• Density is a measure of temperature in a given volume.
• Density is a measure of how much volume is contained in a given mass.
• Density is the amount of molecules in a given area.

• Density is a measure of pressure exerted by a substance.
