Phi values increase arithmetically as the grain size decreases geometrically (3, 5) 4. the wearing away of the earths surface by the action of wind, water or ice dragging sediment over or hurling it at a surface (8) 5. the transport of material by bouncing (9) 6. the transport of material by rolling + sliding along a surface (8) 7. the wearing down of sedimentary grains due to collisions with other grains during transport (9) 10. defines the relationship of the outline of a grain to a circle. A grain with few sharp corners has a high degree of roundness (9) Down 2. the transport of material in water or air, without it touching the earths surface (10) 3. a measure of the extent to which a sediment is well sorted + well rounded (8, 8) 8. the wearing away of the land surface + removal of sediment by means of transport (7) 9. the transport of ions dissolved in water, particularly K, Ca + Na (8)
