Mercury barometer
Aneroid barometer
Digital barometer
Hydrostatic barometer
Which pressure system is usually associated with fair weather?
Low-pressure system

Define atmospheric pressure in your own words.
Explain why atmospheric pressure decreases with altitude.
State the basic formula for pressure and explain the meaning of each variable.
Give two advantages and two disadvantages of mercury barometers compared to aneroid barometers.
Calculate the atmospheric pressure at a height of 1,000 m using the hydrostatic equation, given that: - Density of air, ρ = 1.225 kg/m³ - g = 9.8 m/s² - h = 1000 m
A mercury barometer shows a column height of 750 mmHg. Convert this pressure into pascals. (Hint: 1 mmHg = 133.3 Pa)
