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)

Greater slope

Farmington River

Erosion/Deposition: Moving Water (Rivers) Greater slope

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
