Several students placed large rocks in several locations throughout the stream bed. The experiment was repeated using the rock
stream bed instead of the sandy stream bed. The rocks did not move in all three sets of trials although the speed varied Explain.
The was not enough gravitational force to move the rocks
B)
The sand provided a medium for the rocks to stick to and they could not be
moved.
Regardless of incline and velocity, the water did not have enough kinetic
energy to move the rock,
The greater the incline and velocity of the stream water, the more likely
that the rocks would travel to the mouth
