FAQ
Frequently Asked Questions
No, it is a specialised technical term used almost exclusively in geology and related earth sciences.
No. The verb form is 'evaporate'. 'Evaporite' is only a noun (and its derivative adjective 'evaporitic').
Halite (rock salt), gypsum, anhydrite, and sylvite are classic examples.
Not necessarily extreme heat, but it does require sustained net evaporation exceeding precipitation or inflow, which is common in arid climates.
