Geology Exam #2 pt 3. Practice Worksheet

the total area drained by a stream and it's tributaries (smaller stream flowing into larger stream)
Ridge or high ground that divides one drainage basin from another
Volume of water flowing past a given point in a unit of time
dissolving of rocks
large or heavy particles that travel on the streambed like sand and gravel
large particles that travel along the streamed by rolling, sliding, or dragging
shows sediment action as function of stream velocity and grain size
medium particles (sand) travel downstream by bouncing along, sometimes contact with stream bed or suspended in water
Sediment is small/ light enough to remain above the stream bottom by turbulent flow (silt, clay)
contains sediment deposited as numerous bars around which water flows in highly interconnected small channels
Flow faster along outside of bends and more slowly along the inside
downhill slope of the streambed
may form when a new, shorter channel is cut through the narrow neck of a meander by lateral erosion
cut off meander becomes crescent shaped
slightly raised banks with respect to the flood plain known as natural levees
body of sediment deposited at the mouth of a river when flow velocity decreases
Process of deepening a valley by erosion of the streamed
Form from downcutting combined w/ mass wasting and sheet erosion
limit of downcutting (stream adjusts to sea level)
widens stream valleys by undercutting of stream banks and valley walls as stream swings from side to side across valley floor
deposition on inside of the curve
heat or high temp is a dominant factor
a solid-state changed to rocks interior (no melting)
majority of metamorphic rocks on earth's surface occurs at great depths, foliated texture
