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
