Earth and Space Science 090 - Lesson 14 Study Guide - Surface WaterMovementObjectives1. Explain how surface water can move weathered materials.2. Explain how a stream carries sediment.3. Describe a floodplain.Key Questions1. Describe ways in which moving water can carve a landscape.2. Explain the three ways in which a stream carries its load (sediment).3. What is the relationship between the carrying capacity of a stream and its discharge and velocity?4. Explain why little water from runoff seeps into the ground in areas of steep slopes.

Thinking Critically: Under what conditions might a stream’s volume increase, and under what conditions might itdecrease? How would the size of the sediment particles in the stream’s load differ in the two situations?7. Making tables: Design a data table that compares how silt, clay, sand, and large pebbles settle to the bottom of astream as the velocity of the water decreases. For help, refer to the skill handbook.
