(a) Write each population in scientific notation.
(b) About how many times larger was the population of the United States than the population of
Columbus, Ohio? Round to the nearest hundredth

70,000 + 6,000 + 800 + 30

step-by-step explanation:

i dont get the question

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.
