the crevasse from the same point with a downward velocity
of 4 m/sec, when will it hit the bottom and how fast will it be
going when it does?

answer:   2 multiplied by x =24

step-by-step explanation:

5 + 8 +7 + 4 + 0 +1 = 25

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.
