More angular rock chips will abrade slower than smooth, round rock chips.
Other factors that affect stream-water velocity are the size of sediments on the stream bed ... Stream water also has a dissolved load, which represents (on average) about 15% of the ... The solubility of these ions is not affected by flow velocity.
Answer:
What effect does angularity have on the rate of stream abrasion?
-More angular rock chips will corrode slower than smooth, round rock chips.
What effect does solubility have on the rate of stream abrasion?
The solubility of a substance at a given temperature is the amount of it required to produce a saturated solution in a given amount of the solvent at that temperature. Whenever a substance is described as soluble or insoluble in a solvent it is taken for granted, unless otherwise stated, that the temperature is about room temperature. If the solid disappears, the substance is obviously soluble. When a bottle of soft drink is opened, bubbles of the dissolved gas, carbon dioxide, are seen leaving the liquid. If the soft drink is warmed, more bubbles of the gas leave the liquid because in general, gases are less soluble in hot liquids than in cold liquids.
