Geology 101: Streams

15 Points Per Correct Answer - No time limit  

1. Speed and direction of stream flow. Velocity Mass Speed Acceleration

2. Steepness of the stream channel. Measured as the vertical drop per unit of horizontal distance. Discharge Stream gradient Graded Stream Ultimate base level

3. Volume of water passing a point in a stream in a certain amount of time. Bed load Discharge Base load Suspended load

4. The lowest elevation to which a stream can erode downward. Graded stream Velocity Discharge Base level

5. What is ultimate base level? Answer: (Two Words)

6. Process by which, over time, the stream gradient is adjusted to yield the velocity required for transportation of the load supplied from the drainage basin. Sloping stream Graded stream Active stream Digging-down stream

7. Liquid is shot hard enough so that erosion occurs. Solution Hydraulic action Abrasion Saltation

8. Erosion by washing debris in the stream next to debris that is in place. Hydraulic action Saltation Solution Abrasion

9. Everything carried by the stream. Cart Strength Load Velocity

10. Solid material that is carried within the stream. Floating load Dissolved load Suspended load Bed load
