If f(x) = 3x - 1 and s(x) = 2x + 1, which expression is equivalent to 3(6)-1 2(6) + 1 (6) 2(6)+1 36-1 26+1 (6)-1 (6) + 1 mark this and return save and exit next submit
evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.
crystalization in molten earth: slow cooling over time. (hundreds to millions of years)
crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)
crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
