EARTH 10 Lecture Notes - Lecture 5: Silly Putty, Rubber Band, Anticline
Document Summary
Earth can behave : elastic: stress removed, earth springs back (like a rubber band, plastic: stress removed, earth keeps new shape (like silly putty) - folding, brittle: breaks - faulting. Faults : fracture in a rock along which one side has moved relative to the other side. Types = normal, reverse, and strike-slip earthquakes. Horsts and grabens landscape formed by faulting. Rifting, lots of normal faults, blocks move up and down (german words) Generally found in compression zones, converging plate boundaries. Types = anticline (upward arched fold with the oldest rocks in the center) and. Foot block = holds up hanging block syncline (downward with youngest in the center) 98% is 8: o, si, al, fe, ca, na, k, and mg. Mineral: naturally-occurring, inorganic (not from living matter) solid, with a known. Crystalline : any substance whose tos are arranged in a regular, periodically repeated chemical composition and a crystalline structure pattern ( crystalline structure )
