A man's wife is upset because when she hugs him with her hands on his left shoulder blade, "it feels creepy." This came on gradually after a recent severe left-sided rotator cuff tear. How long does it usually take to develop muscular atrophy with increased prominence of the scapular spine following a rotator cuff tear?

A) 1 week
B) 2–3 weeks
C) 1 month
D) 2–3 months

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
