ACTUAL Questions and CORRECT
Answers
Polarity - CORRECT ANSWER - Causes water to be attracted to itself and act in clusters.
Also causes attraction to ions and colloidal surfaces
Hydrogen bonding - CORRECT ANSWER - bonding to O, N, F
Capillary movement - CORRECT ANSWER - ability of a liquid to flow in narrow spaces
without or opposing gravity
cohesion - CORRECT ANSWER - water attraction to itself.
causes surface tension
Adhesion - CORRECT ANSWER - Attraction of water molecules for solid surfaces
Matric force - CORRECT ANSWER - Most important force.
attraction of water to soil solids.
Osmotic forse - CORRECT ANSWER - attraction of water to ions or other solutes
Gravitational force - CORRECT ANSWER - movement of water due to gravity
soil water potential - CORRECT ANSWER - Potential of water to move due to different
forces
, matric potential - CORRECT ANSWER - In unsaturated soils, movement may be slow,
water to colloids
osmotic potential - CORRECT ANSWER - Water moves from low solutes to high solutes,
common b/t soil and plants
volumetric water content - CORRECT ANSWER - Volume of water/mass of dry soil
mass water content - CORRECT ANSWER - mass of water/mass of dry soil
saturated flow - CORRECT ANSWER - Movement when all of the pores are full
unsaturated flow - CORRECT ANSWER - Movement when only large pores are filled
with air
saturated hydraulic conductivity - CORRECT ANSWER - ease in which pores of a
saturated soil permit water movement in any direction (how hard to push water to drain)
Ksat - CORRECT ANSWER - Depends on size and configuration of soils.
Affected by: management practices and texture
Ksat with texture - CORRECT ANSWER - Coarse= high ksat
Higher ksat in well aggregated clay than compacted loam
preferential flow - CORRECT ANSWER - rapid movement pathway through soil
infiltration - CORRECT ANSWER - the entering of water into the soil
