Kamillah decides to calculate the height of the Empire State Building. She walks I mile (5280 feet) away from the tower and finds that she has to look up
15.5° to see the top. Assuming Manhattan is flat, if Kamillah's eyes are 5 feet
above the ground how tall is the Empire State Building?

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.

its a lot blury
