What is sediment?

• the process of rocks being broken down and carried away
• bits of rock, sand, and silt caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material

Compared to the stream speed between point X and point Y, the stream speed between point Y and point Z is most likely

• greater, since the slope of the land decreases

• greater, since the slope of the land increases

• less, since the slope of the land decreases

• less, since the slope of the land increases

The process in which sediment settles out (drops to the bottom) of the water or wind that is carrying it

• Weathering

• Erosion

• Sedimentation

• Deposition

What do we call a bend or curve in a slow-moving river?

• Meander

• Tributary

• Discharge

• Slope

Which erodes/breaks down more rock:

• A fast-moving stream

• A slow-moving stream

What can form if a meander "pinches off" from the main channel?

• Oxbow Lake

• Tributary

• Point bar

• Cut bank

Sediment is deposited in a river delta because the

• velocity of the river decreases

• force of gravity decreases

• volume of the river increases

• gradient of the river increases
