Please help with the following earth science questions. Thank You! 1.  Columnar jointing in solidified lava forms due to A. uniform tensile stresses throughout the flow B. contraction of the cooling lava flow C. progressive step-by-step fracturing from the top and bottom of a cooling flow D. all of these answers are correct 2. Crack-In-The Ground and the Four Craters next to and parallel to it are examples ofA. terrane boundaries and stitching plutons B. plume-related uplift and post-caldera lava flows C. compressional tectonic folding D. crustal extension and rifting with volcanism E. subduction zone volcanism  3. The generally accepted explanation of the behavior of the rocks on both sides of a fault during rupture that produces the waves of an earthquake is A. plate tectonics B. elastic rebound C. brittle springback D. ductile deformation E. basal slip
