3. 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.

4. Runoff = water that flows downslope along Earth’s surface
May join a stream, evaporate, or accumulate and turn into GROUNDWATER.
4 main conditions determine whether if runoff becomes groundwater:
1. Soil Composition
2. Rate of Precipitation
3. Vegetation
4. Slope

5. Stream Systems Not all precipitation doesn’t
enter the ground immediately.
TRIBUTARIES – Rivers that flow into other rivers/streams
WATERSHED – all of the land area that contributes/runs off into the stream
DIVIDE – a high land area that separates one watershed from another.

6. 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.

7. Floods = Occurs when water spills over the sides of the stream’s banks
Floodplain = broad, flat area that extends out from the water
