GEOL 103 Study Guide - Quiz Guide: Fuel Cell, Chain Reaction, Sulfur
Document Summary
The ways to understand and classify is to consider several things: type of material; type of motion; rate of motion. Rock fall (fast)- material breaks free fomra vertical wall or very steep slope. Slides (fast)- a single, intact mass of rock, soil or unconsolidated sediment becomes detached and moves rapidly down. Slumps (slow to fast)- a downward and outward movement of an intact mass of unconsolidated material along a curved surface. Flows (rapid)- a mixture of mostly unconsolidated particles that moves downslope like a viscous fluid. Materials behave like fluid: mudflows (lahars, earthflows, debris flows- a slurry of water and particles larger than mud. Creep (slow)- extremely slow movement of soil and regolith 1- 10mm/yr: factors- heaving of soil: expansion and contraction. Solifluction (slow)- creep that occurs in permafrost: melting of soil water occurs form the surface down, permafrost prevents downward percolation, can pluck and move cobble.
