Rivers

Objectives

1) Describe the four types of erosion and the three methods by which rivers transport debris
2) Compare and contrast youthful, mature and old rivers in regards to their characteristics, landforms, and uses to humans
3) Describe how the four types of deltas form and give examples of them in the world
4) Explain how rivers can rejuvenate and thereby gain their youthfulness
5) Recognize trellis, dendritic, and radial drainage systems
6) Explain how and why inner and outer river banks vary from each other
7) Explain how rivers are complex natural systems that greatly affect human activity and also can be completely changed by humans such as through building dams
8) Explain the advantages and disadvantages of hydro dams
9) Draw and label the hydrologic (water) cycle.

Rivers are agents of erosion and deposition. In this unit, you will explore the various components of a river system and the resultant landforms.
