Science Rivers Quiz

There are 3 methods that sediments are transported by water. This is called hydraulic action.

The first is called solution. The particles are small enough to be dissolved in water.

Particles such as silt or clay are called colloids. They are transported by suspension.

Sand, gravel, pebbles, and cobbles are transported by bouncing and rolling. These particles are called bedload.

Headward erosion contributes to the growth of tributaries.

Stream piracy occours when tributaries combine.

Base level is the lowest elevation a river can erode to. Equals elevation at the mouth.

The Mississippi River flows into the ocean. The base level is 0.

(It had to be the number they call Mr. Billion)

Rate of flow, velocity or speed depends on two things.

Gradient is the slope of the land. Equation- steep = fast.

Volume is the amount of H2O. Equation- Lots = fast.
