  12. 12. How Does streams erode their channels?<br />Streams generally erode their channels lifting loose particles by abrasion grinding, and dissolving soluble material.<br />
  13. 13. What causes floods?<br />Most floods are caused by rapid spring snow melt or storms that bring heavy rains over a large region.<br />
  14. 14. What is the relationship between stream and a drainage basin?<br />Every stream has a drainage basin, A drainage basin is the land area that contributes water to a stream.<br />
  15. 15. How do streams transport sediments?<br />Streams transport sediment in three ways<br />In solution<br />In suspension<br />Scooting or rolling along the bottom<br />
