I need help ASAP thank you

V = 175 yd^3

Step-by-step explanation:

V = B*h

The base is the area of the triangle

B = 1/2 (5*7) = 35/2

so

V = 35/2 * 10

V = 175 yd^3

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.
