Document Summary
In metamorphic rocks, layering formed by mineral grain alignment or compositional bonding is called. The original source of gneiss is generally thought to be. The main source to create foliation in sedimentary rocks can be. In the time scale, igneous rocks can occur anytime from the precambrian to the cenozoic. In the rock classification, slate is assigned to the non-foliate metamorphic rock. In general, schist is considered as a hard rock instead of a soft rock. Earthquake the vibrations caused by rocks breaking under stress. The underground surface along which the rock breaks and moves is called a fault plane. These vibrations are called seismic waves and they travel in all directions from the hypocenter (focus) of the earthquake. Hypocenter (focus) the point where the energy is produced during an earthquake (in the ground) Epicenter the point on the surface directly above the focus of an earthquake. Types of earthquake faults: (look up pics)
