๐Ÿ’ก A quick map of how the big ideas of this chapter connect together.

Pressure force per unit area (unit: pascal, Pa) Liquid pressure depends on height; all directions Air pressure atmospheric, all directions Wind high to low pressure Overhead tanks height gives pressure Dam base broad withstands pressure Sucker / breathing air pressure balance Sea / land breeze day & night winds Fast wind lowers pressure Storms → Cyclones thunder, lightning, spinning cyclones
Pressure — force per unit area (unit: pascal, Pa)
↓
Liquid pressure
depends on height; acts in all directions
Overhead tanks
placed high for a strong stream
Dam base
broad to withstand pressure
Air (atmospheric) pressure
air presses in all directions
Sucker
held on by outside pressure
Not crushed
inside pressure balances outside
Wind
air moves high to low pressure
Sea / land breeze
day and night winds
Fast wind
lowers pressure; lifts roofs
Storms & Cyclones
strong winds, rain, thunder
Lightning
charge separation in clouds
Cyclone
spinning storm; calm eye
