gypsum rock often forms when salt evaporates just like h2o 555 it does to that what i think 89392
Gypsum is formed underwater, usually between layers of shale and limestone. When the water evaporates and the area dries, the gypsum becomes solid "rock" gypsum.
Gypsum is in Plaster and Silica is in silicone.
yes its softer
Very widely is the short answer. If you have a crack at 'gypsum' in a reference work such as wikipedia, you'll find reference to the caves of giant gypsum crystals in the Naica mine in Mexico. These crystals are up to 12m long, 4m thick, and weigh up to 55 tons! But with a temp of just under 60oC and an RH of >>90%, time to explore is limited. Back to the Q, large evaporite deposits of gypsum are found near the surface of the earth.

Employees at National Gypsum get paid bi-weekly, or every other week.
You might consider Alabaster.
I think quartz
No.
gypsum
Gypsum and Halite are evaporites because they are formed through the evaporation of water to form crystals.
No it is not a salt. Gypsum is a mineral that occurs in nature as flattened and often twinned crystals and transparent cleavable masses called selenite.
