Question 1 of 27070

Atmospheric pressure at sea level is equal to __________.

🔍 Key Concepts

• Standard atmospheric pressure at sea level as defined in basic meteorology and oceanography texts • How the same physical pressure can be expressed in different units (millibars, inches of mercury, psi) • The idea that multiple units can all be correct if they represent the same numerical value of standard pressure

💭 Think About

• First, recall the commonly used value for standard sea-level pressure that you’ve seen most often in weather reports or barometer readings—what units was it in? • Then, think about whether the other choices might simply be different units for that same standard pressure value. • Ask yourself: if one choice is the standard value in one unit, could the others be the same physical pressure in different units, or are any of them clearly unrealistic?

✅ Before You Answer

• Identify the numeric value you know for standard sea-level pressure in any unit and match it to one of the options. • Consider whether weather maps and barometers typically use millibars (mb or hPa) and what number you usually see there for average pressure. • Consider whether shipboard barometers often show inches of mercury and if that common reading aligns with another value given.
