9.1 Surface Water Movement
The Water Cycle = repeated evaporation and condensation powered by the sun.
The pathway may spend time within a living organism or as part of a glacier, lake, ocean, etc.
Runoff= water that flows downslope along Earth’s
surfaceMay join a stream, evaporate, or accumulate
and turn into GROUNDWATER.4 main conditions determine whether if
runoff becomes groundwater:1. Soil Composition2. Rate of Precipitation3. Vegetation4. Slope
Stream SystemsNot all precipitation doesn’t
enter the ground immediately.TRIBUTARIES – Rivers that flow into other
rivers/streamsWATERSHED – all of the land area that
contributes/runs off into the streamDIVIDE – a high land area that separates one
watershed from another.
Stream Load= The material that a stream carries.
The stream load can be carried in 1 of 3 ways:1. Materials in suspension – large materials are carried in faster moving water.2. Bed Load – larger pieces of a stream that can’t be carried by water, but instead is pushed and rolled.3. Materials in Solution –minerals that are dissolved and carried away in the water.
Floods= Occurs when water spills over the sides of
the stream’s banksFloodplain = broad, flat area that extends out
from the water
