Aplane is flying at an altitude of 32,000 feet. the distance between the plane and a radio tower on the ground is 50,000 feet. what is the angle of depression between the plane and radio tower? (round to one decimal place)

a. 0.6 degrees
b. 0.7 degrees
c. 32.6 degrees
d. 39.8 degrees

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.

if i knew id you bro,, my bad
