Document Summary
Chapter 15, p. 330-332 earth: an introduction to physical geology 4ce. Water resides in all four reservoirs of the earth system; hydrosphere, Dr. clark atmosphere (vapor), biosphere (we are ~65% water), and even the geosphere (in magmas, in crystal structures), and thus participates in the hydrologic cycle the bulk resides in oceans, at 95+%, and is this: saline/salty. Glaciers/polar ice account for almost 3%, or ~3/4 of fresh water (its state. ), groundwater at ~1% (its characteristics noted: noted: much is connate or saline, not potable), and lakes plus rivers <0. 01% Note in passing the various flows and exchanges between reservoirs. Chapter 15, p. 329-358 earth: an introduction to physical geology 4ce. We use the term stream for any body of water whose flow is confined to a. Competence: is the largest grain the stream can move, controlled primarily by competence, capacity, and load defined: stream velocity; thus a stream tends to sort sediment by grain size along its length.
