a. about 54.6 units and 39.4 units
c. about 46.8 units n 64.6 units
b. about 63.9 units and 41.0 units
d. about 67.5 units and 36.8 units select the best answer from the choices provided

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

step-by-step explanation:

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.
