Across
- 4. deposition often occurs inside one of these river bends
- 6. water can pass through
- 7. what rivers deposit when they slow down & lose energy
- 8. heavier particles may not be held in the flow all the time but may be bounced along the bed
- 13. the high-sided canyon a river runs through after creating a waterfall
- 15. rain that flows sideways through soil
- 17. In the process of attrition these are carried downstream, knocking against each other, wearing each other down
- 19. when a river is flowing at such a rate that material can no longer be supported and it sinks to the river bed.
- 21. water cannot pass through
- 22. the sheer force of the water pounding into the bed and banks can dislodge material.
- 23. particles are carried by the river current, some in the flow and some bounced along the river bed.
- 24. particles being carried downstream knock against each other, wearing each other down. This results in smaller, rounder particles downstream.
- 25. this effect is another way of describing abrasion
- 29. process of water becoming a gas
- 30. the direction a gorge moves after repeated waterfall formation
- 31. the heaviest particles are rolled along the bed. Such particles may only be moved when the river has a large volume of water in it.
- 32. water that runs along hard ground
- 33. the ridge or crest line dividing two drainage areas; the border of a drainage basin
- 34. process of gas becoming water
Down
- 1. the combination of traction and saltation
- 2. the hard rock left hanging, before collapsing, when soft rock is eroded by a waterfall
- 3. moving water throws particles it is carrying against the bed and banks of the river which dislodges material – sand paper effect.
- 5. the area where water falls at high force, causing erosion of soft rock in waterfall formation
- 7. where particles are carried along in the flow and are not in contact with the river bed. This can often amount for 90% of the total load carried by a stream
- 9. a flowing together of two or more streams, rivers; the point where they join
- 10. Some rocks forming the banks and bed of a river are dissolved by acids in the water.
- 11. some minerals (particularly in limestone areas) dissolve easily in water and are not visible to the naked eye
- 12. water held in rock, underground
- 14. the type of rock that isn’t easily eroded, but will break down and be transported as part of waterfall formation
- 16. the science of rivers, seas, lakes, streams. Mix the words for a serpent with 9 heads + bio----.
- 18. loss of water from the soil both by evaporation and by transpiration from the plants growing on it
- 20. measured in m3/s, also known as discharge, the volume of water that passes through a point in a river. The Rhine averages 2,200 m3/s
- 23. a stream that flows to a larger stream or other body of water
- 26. the area drained by a river and all its tributaries. Also called catchment area, drainage area
- 27. the process of rock being gradually broken down into smaller particles by water for example.
- 28. the point at which a river or stream flows into a lake, sea or ocean
