Document Summary

Minerals: naturally occurring inorganic substances, orderly arranged of atoms. Mineral properties: color, hardness, crystal form, breakage pattern, taste, feel, smell, etc. Igneous: intrusive (from magma); formed in earth; forms slowly; coarse grained, extrusive (from lava); formed on above earth; fine grained. Sedimentary: clastic (pieces of other rocks, chemical (biological or inorganic precipitation) Metamorphic rocks: buried and compacted by heat and pressure but don"t melt, crystals can be reorganized, metaconglomerate, very resistant to erosion, referred to as bed rock. Nature of ground materials affect earthquake energy. Different materials respond differently to an earthquake. Depends on their degree of consolidation: seismic waves move faster though consolidated bedrock, move slower through unconsolidated bedrock, move slowest through unconsolidated materials with high water content. Material amplification: energy is transmitted to the vertical motion of the surface wave. Building construction is a common denominator: poor construction: more death, el salvador showed location of buildings is also an issue, california and chile: stronger earth.
