Packet L: 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 (10[1])a transition (-5[1])zone in the lithosphere that typically corresponds to the region (-5[1])of maximum seismicity. In regions of the crust with this property, compression of rock may cause it to fold into synclines (10[1])and anticlines. (-5[1])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 (10[1]-5[1])fracture. (10[2])For 10 points, name this property of materials (10[1])that can undergo (10[1]-5[1])significant (10[3]-5[1])plastic (-5[3])deformation (10[1]-5[5])before (-5[1])fracture, (10[1]0[1])like (10[1])copper.
