1 answer

Here are the responses based on the definitions and scenarios you've provided:

  1. Erosion: gradual wearing away or destruction of a material by moving air or water.
  2. Stream Capacity: the maximum amount of solid a stream can carry at one time.
  3. In rocky terrain, HIGH water volume and HIGH slope/gradient: narrow, deep.
  4. In rocky terrain, MEDIUM water volume and LOW slope/gradient: wide, shallow.
  5. In rocky terrain, LOW water volume and HIGH slope/gradient: narrow, shallow.
  6. In glacial mountain terrain, HIGH temperature and LOW slope/gradient: flat-bed.
  7. In glacial mountain terrain, MODERATE temperature and LOW slope/gradient: flat-bed.
  8. In hills and plains terrain, HIGH water volume and LOW slope/gradient: wide and meandering.
  9. In hills and plains terrain, LOW water volume and MODERATE slope/gradient: narrow and meandering.
  10. Ocean waves at the mouth of a river influencing delta/estuary formation: Ganges-Brahmaputra Delta.
  11. Large area of river outflow sheltered from ocean waves: Gulf of St Lawrence Estuary.
  12. Arcuate delta shape: fan or triangle shaped.
  13. Cuspate delta shape: pointed or tooth shaped.
  14. Inverted delta shape: pointed or tooth shaped.
  15. When there is a HIGH slope/gradient and a HIGH water volume: braided and wide; When there is a HIGH slope/gradient and a MODERATE water volume: braided and narrow.
  16. When there is a LOW slope/gradient and a MODERATE water volume: meandering.

These answers align with common geological knowledge related to rivers, streams, and their formations.
