26) Structural
27) Stress; strain
28) Syncline
29) domes
30) joints
31) Because they formed at such high temperatures and pressures.
32) Lithostatic; directed
33) compressional; brittle
34) Paleobiogeography
35-36) Fossil Limestone – Organic Reefs
Coal – Temperate Swamps
Evaporites – Deserts
37) Caledonians
38) Rifting of Gondwana
39) Curie Point; 580°
40) Ring of Fire
41-46) (Transform) Shear stress; strike-slip faults; absent volcanism; San Andreas – southern California example
(Divergent Ocean-Ocean) Extensional stress; normal faults; common volcanism; Mid-Atlantic Ridge example
(Convergent Continent-Continent) Compressional stress; reverse/thrust faults; absent volcanism; Himalayas example
47-48) Antarctica, Africa, S. America, India, Australia
49-50) Hot spots remain fixed and the moving overlaying plate displaces volcanic islands in the direction and at the rate the plate moves.
