Runoff

_________________

(_________________________)
 ______________ = water and

__________ in an area
3. _________________steep slopes = more
runoff

Particles and rock
materials carried by
stream = ______________
Stream _____________

_________________________pushed or rolled
_____________- picked up
and carried by force of
moving water
___________ and other small
particles- dissolved in water
Stream Erosion

 Steams cause erosion by
___________________
 Sediments carried by streams
constantly collide with rocks,
chipping away pieces and
wearing down the rocks
