The document outlines four laws of stream and river formation: 1) Steeper slopes produce narrower and deeper channels while gentler slopes produce wider and shallower channels. 2) Rivers will take the path of least resistance around obstacles. 3) Younger rivers are straighter while older rivers have more curves and meanders from erosion. 4) Deltas form at river mouths as the water slows and sediments are deposited where the river meets the ocean.
2. Law 1- Steepness of Slope
 The steeper the slope is, the faster
the water runs off
 The faster the water runs off, the
more erosion occurs
 Steep slopes produce narrow, deep
channels
 Gentle slopes produce wide
shallow channels
3. Law 2- Obstacles
With obstacles in its path, a stream
will always take the PATH OF
LEAST RESISTANCE
4. Law 3- Older Rivers
 Younger rivers tend to be
straighter, and older rivers have
more meanders (curves).
 Older rivers have more erosion on
the outside of a curve, and more
deposition on the inside
5. Law 4- River Deltas
 Deltas form at the mouth of the
river
 River water slows down as it
reaches the ocean
 Sediment from the river is
deposited as the water runs into
the ocean water
6. Law 4- River Deltas
 Deltas form at the mouth of the
river
 River water slows down as it
reaches the ocean
 Sediment from the river is
deposited as the water runs into
the ocean water
