Erosion/Deposition: Moving Water (Rivers) D.E.Q. How does Moving Water (Rivers)
change the surface?

Erosion/Deposition: Moving Water (Rivers)
Greater slope will: (Determined by terrain)Increase the force of gravity, and in
return:○ The V-shaped river valley will be deeper○ Have faster moving water○ Carry more sediment (cause more erosion)○ Have a narrower river○ Take a straighter course

Erosion/Deposition: Moving Water (Rivers)
Lesser slope will: (Determined by terrain)Decrease the force of gravity, and in return:
○ The V-shaped river valley will be shallow○ The water will slow down○ The river becomes wider○ The sediments will start to settle
(DEPOSITION)○ The river’s course will meander (bend and
loop)○ Delta will form where river exits into a larger
body of water
