water systems

2. Bends in the stream
4. group of natural processes that break rock into smaller pieces over time.
7. U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water.
8. the lowest point to which a river can erode its channel.
11. Allows water to pass through it
13. the course that the water flows in a river. This is usually where you find the steepest gradient. You may also find V-shaped valleys here.
15. when rock and soil are transported.
16. The stream bed has soft and hard rock. The softer rock erodes MORE QUICKLY as the river flows over it.
18. A fan-shaped deposit of sediment that forms when a stream drops downward from a higher elevation and encounters the valley floor.
20. the slope or steepness of the river. The steeper the gradient, the more energy.

1. Does not allow water to pass through it
3. Determines how much groundwater can be stored
5. the placement of the sediments
6. fan-shaped sediment deposit where a river empties into an ocean at the mouth.
9. a moving body of water that eventually connects to an ocean
10. when cracks fill with water and undergo a repeated cycle of freezing and thawing, causing rocks to crack apart
12. areas of shallow, fast-flowing water in a stream
14. where one stream empties into another
17. how fast or slow the river is moving. This determines the rivers ability to erode sediments
19. form when water flows to a place that is surrounded by higher land on all sides
