The Force of Moving Water Answers

A river’s ____ is the sediment and other deposits picked up as a result of abrasion. a.slopec.flowb.volumed.load

A fast flowing river can carry very little sediment.

What type of energy is involved when a river moves sediment and erodes its banks?a.chemical energyb.gravitational energyc.potential energyd.kinetic energy

How would a fast-flowing river be most likely to move sand-sized particles of sediment?a.It would lift them and carry them downstream.b.It would dissolve them completely in solution.c.It would roll or slide them along the streambed.d.It would deposit them on the streambed.

Please select the word from the list that best fits the definition

What happens as gravity pulls water down a slope?a.Kinetic energy changes to potential energy.b.Both kinetic and potential energy vanish.c.Energy is stored for future use.d.Potential energy changes to kinetic energy.

What causes most sediment to wash or fall into a river?a.frictionb.depositionc.mass movement and runoffd.turbulence

Water at the top of a slope has potential energy.

The volume of water that moves past a point on a river in a given time is called the river’sa.flow.b.slope.c.load.d.turbulence.

As a river’s slope increases, the power of the river to cause erosion usually decreases.
