Vocabulary
Erosion- Process by which water,ice,gravity, and wind move sediment and soil from one place to another.

Water cycle- Continuous movement of water between the land,ocean, and atmosphere.

Tributary- A stream that flows into a lake or into a bigger stream.

Watershed- The area of land that is drained by a river system.

Divide-Watersheds are saperated from each other by a higher ground.

Channel- A path that a stream flows.

Load- Materials carried by a stream.
Lesson 1: The Active River
Key Concept: Water running downhill is the dominant process in shaping the landscape.

Explanation: This concept is trying to explain that water is is an important part of a process shaping a landscape which is called erosion. As an example the water running downhill which is now called the Colorado River cut down into the rock which now is called the Grand Canyon.

Lesson 2: Stream and River Deposits

Rivers and streams are dynamic systems that erode , transport sediment, change course, and flood their banks in natural and recurring patterns.
Explanation: This concept is trying to say that alot of water erosion comes from rivers, taking sediment and then depositing it somewhere else around the world. For example, the Nile River taking sand and dirt and then depositing it on the beach.
Vocabulary
Deposition- the process in which material is laid down
Delta- a fan shaped mass of material deposited at the mouth of a stream
Alluvial fan- a fan shaped mass of material deposited by a stream when the slope of land decreases sharply
Flood Plain- an area along a river that forms from sediment deposited when the river overflows its banks
Math Practice
A river flows at a speed of 2 kilometers per hour.How many kilometers would you flow if you floated for 10 hours ?

Once the Missouri and the
Mississippi River had a flood that
overflowed their banks in 1993.
Here is a picture of the rivers today.

5.Sand and dirt

Through the Rocky Mountains is the Continental Divide.It separates the Gulf of Mexico which flows into the Pacific Ocean and watersheds which flow into the Atlantic Ocean.
Rapids and falls occur where the rivers flow over hard, resistant rock.
Pebbles and boulders are an example of a bed load. Sodium and calcium are examples of
