a tower is composed of a prism with a square base and a pyramid. the base length is 20 meters, and the height of the prism is 40 meters, while the slant height of the pyramid is 10√2 meters. what is the total surface area, including the bottom base?
a. 400√2 + 3,600 m^2
b. 200√2 + 3,600 m^2
c. 400√2 + 400 m^2
d. 4000√2 m^2

400√2 + 3,600 m2

large crystals result from very slow cooling.

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.
