• AltitudeAltitude: The altitude of a location is its vertical distance above : The altitude of a location is its vertical distance above sea level sea level

• Boiling point is lower at high altitudes- it is faster to boil a pot of Boiling point is lower at high altitudes- it is faster to boil a pot of water on a mountain than at the Jersey Shorewater on a mountain than at the Jersey Shore

• BUT it takes longer to cook food- why?BUT it takes longer to cook food- why?

This is a low altitude situation

This is a high altitude situation!
