Round 12: Tossup 11

In earthquake engineering, a structure’s earthquake resistance is quantified by a combination of “demand” for this property and behavior class. This property characterizes the conditions in which mylonites shear and undergo metamorphism. This material property exists below a transition zone in the lithosphere that typically corresponds to the region of maximum seismicity. In regions of the crust with this property, compression of rock may cause it to fold into synclines and anticlines. Fault zones extend downwards into a shear zone with this property, which exists at depths where temperature and pressure is high enough that rocks no longer undergo brittle fracture. (10[1])For 10 points, name this property of materials that can undergo significant (10[2])plastic (-5[1])deformation (-5[1])before fracture, like copper. (10[1]0[8])■END■
