Atmospheric Pressure

• Pressure = Force per unit Area

• Related to Density

Vertical Distribution of Mass

• Density = mass per unit volume

• Density decreases with increasing altitude

• Figure from apollo.lsc.vsc.edu/classes/met130

Pressure Change with Height

• Like density, pressure decreases with increasing altitude.• It does so at a greater rate in the lower atmosphere
