Only problem 1-1b

I included the example problem 1-1A

1-1. In the following sketches of a two-piece jigsaw puzzle, plate A is stationary and AVH, the linear velocity of plate B, is given by the arrow. The units of velocity are mm/yr=km/my; In (l) and (m) the motion is not linear and plate B has an angular velocity of 5%my about the Euler pole E. In all cases plate B is being thrust under plate A, except where the polar ity is indicated with " U " and "D". (a) Label the boundanes in the first column as ridge, trench. or transform with appropriate simbols (b) Sketch in the second column what the plates would look like todav (t=0) if they first separated at time t0=10 Ma Show isochrons at intervals of 4my and color or stipple plate B to distinguish it from plate A. The anchor. starfish, and shell are resting firmly attached to the seafloor, which other wise is rather monotonous. Keep track of ahere they move. (c) Non sketch in the third column what the plates would look like today if they first separated at time t0=20Ma Don't be reluctant to use a pair of scissors - the experts do!
