Document Summary
Discharge: d=ac (area of the stream)* va (average velocity with which water moves in the downstream direction) Dissolved load running water dissolves soluble mineral from the sediment. (ions) Suspended load tiny solid grains that swirl along with the water. The capacity of a stream depends on both its competence and its discharge. Terms about stream: floodplain; oxbow lake; point bars/meander neck; stream bed gravel; cutoff. How it forms: local climate must be suf ciently cold, the slope of the surface must be gentle enough, so it does not slide away in avalanches, suf cient snowfall to accumulate. Terms: cirque glacier; valley glacier; piedmont glacier; mountain ice cap; crevass. Zone of accumulation: snow; ow trajectory; equilibrium line. Zone of ablation: sublimation; calving; terminus; iceberg; meltwater tunnel/ stream. Causes: plate tectonics (appropriate attitudes and con guration, concentration of carbon dioxide in the atmosphere (ice can be triggered by mountain building.
