| What separates one drainage basin from another? | high ground
🗑
|
||||
| What is the relationship between stream gradient and average stream velocity? | stream gradient decreases while stream velocity increase down stream
🗑
|
||||
| What is the correct order for where you would find stream deposits starting at the headwaters and going toward the mouth? | gravel, sand, silt
🗑
|
||||
| The smaller the wetted perimeter... | the faster the velocity
🗑
|
||||
| What happens to the wetted perimeter of a stream during a flood? | it increases
🗑
|
||||
| A rapidly city within a humid climate zone experiences a land use change from perdomintly cropland to mostly urban/suburban. A likely natural response would be: | reduced infiltration--increased floodingg
🗑
|
||||
| What is the longest river on earth? | nile
🗑
|
||||
| Where is the majority of the earths water? | oceans
🗑
|
||||
| Where does most evaporation of moisture to the atmosphere occur? | from the oceans
🗑
|
||||
| What happens to most of the water falling as precipitation? | it returns to the atmosphere by evaporation and transpiration
🗑
|
||||
| what is ultimate base level for most streams? | an ocean
🗑
|
||||
| Besides the average precipitation, what determines the size of a stream? | the drainage basin size
🗑
|
||||
| Which type of stream pattern is similar to the pattern formed by tree branches? | dendritic
🗑
|
||||
| Where is stream gradient usually greatest? | headwaters
🗑
|
||||
| What type of load are you observing when you see a muddy stream? | suspended load
🗑
|
||||
| Where are streams most common and why? | southeast US, greatest rainfall
🗑
|
||||
| How is stream discharge determined? | depth x width x velocity
🗑
|
||||
| What is closely related to stream "stage"? | depth
🗑
|
||||
| What is the average period of time that elapses between flood events of similar size? | recurrence interval
🗑
|
||||
| What factor causes the majority of flooding most Midwestern rivers (ohio river)? | brief, heavy storms
🗑
|
||||
| Daily stream discharge rates are displayed on these plots | hydrographs
🗑
|
||||
| A stream with a rectangular cross section has a width of 10 ft and an average depth of 3 feet. The velocity of the water flowing through this segment of the stream is 2 ft per second. What is the discharge of the stream? | 15 ft3/second
🗑
|
||||
| What factors incluence the way rivers flow? | -the underlying geologic structure of faults and or folds
-the speed with which the water is flowing
-dams along a stream channel
-the resistance to erosion of the materials that make up the channel
🗑
|
||||
| A point bar forms due to | river flow slowing down on the side of meander bends, depositing sediments
🗑
|
||||
| A cut bank forms due to | river flow speeding up on the outside of meander beds eroding sediments
🗑
|
||||
| A levee forms due to | river flow velocity decreases, depositing sediments near the channel margins as water spreads out over a floodplain during a flood
🗑
|
||||
| oxbow lake forms due to | as rivers cut off segments of their channel creating curvy looking lakes
🗑
|
||||
| The most common type of drainage basin pattern is____and it is usually associated with____ | dendritic, horizontal sedimentary rocks or sediments
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
