Monique collects data from a random sample of seventh graders in her school and finds that 8 out of 12 seventh graders participate in after-school activities. Write and solve a proportion to estimate the number of seventh graders n who participate in after-school activities if 84 seventh graders attend Monique's school. Solve the proportion for n.

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.
