7. having the same elevation on either side of the ridge or valley. Elevation: the vertical distance between a point and sea level. Relief: the distance between the highest and lowest elevation in a given area. Height: the distance from the base to top; from the floor to the top of your head; the difference in elevation between the top of a hill and the bottom. Mineral composition of igneous rocks: mafic: low sio2, 45-55%, forms at high temperatures; pyroxine, intermediate: intermediate sio2, 55-65%; hornblende, biotite, potassium feldspar (k-spar, felsic: high sio2, >65%, forms at low temperatures; quartz. Depositional environments of sedimentary rocks and characteristics of sedimentary rocks: depositional environments: tell us how and under what conditions ancient sedimentary rocks formed, see table 4. 2 p. 61. Sedimentary rocks are classified by: grain size: tells us energy of transport, classified by rounding: tells us the length of transport.
