5.5.2 Atmospheric Pressure

• Atmospheric pressure is often measured in Pascals (Pa) or millibars
• Atmospheric pressure increases as you go higher in altitude.

  False
• Atmospheric pressure is created by the weight of the air
• Gravity pulls the air towards the Earth's surface, contributing to atmospheric pressure.
• Atmospheric pressure is lower at higher altitudes, in warmer temperatures, and in more humid
• Atmospheric pressure decreases with higher altitude
• Match the type of barometer with its characteristics:

  Mercury Barometer ↔️ Highly accurate but bulky

  Aneroid Barometer ↔️ Compact and portable
• The height of the mercury column in a mercury barometer represents the atmospheric pressure
• Aneroid barometers are more accurate than mercury barometers.

  False
• As you increase in altitude, atmospheric pressure decreases
• Order the atmospheric pressure from highest to lowest based on altitude:

  1️⃣ Sea Level

  2️⃣ Higher Altitudes
