Robert is running on a track that is 3 3 4 miles long. He has run 1 2 5 of a mile. How many more miles are there until Robert reaches the end of the track? A) 2 7 20 miles B) 2 5 9 miles C) 3 7 20 miles D) 3 5 9 miles

the answer is d on edge

step-by-step explanation:

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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.
