Stream Formation

Match the following

• main part of the stream where the majority of the water flows

• Channel

• -part of the stream channel that is above the water

• How are streams classified

• By their ages-and can be identified by landforms

• Stream bed

• part of the stream channel that is below the water

• stream bank

Match the following

• the shape that young rivers always carve out of the land with water

• Bedload or traction

• the amount and size of sediments that it transports

• V-shaped valley

• speed of the water

• Carrying ability

• the large boulders that are moved because of fast moving water.

• Velocity

Young streams Flow ​ (a)   through the valley 

Makes a​ (b)   shaped eventually deepening and ​ (c)   the channel

• quickly
• V
• widening

Mature streams Flow slower and STARTS to ​ (a)   and curve through the valley

​ Saltation- small ​ (b)   and stones are ​ (c)   along the river bed. 

​ (d)   - large ​ (e)   and rocks are rolled along the river bed.

• meander
• pebbles
• bounced
• Traction
• boulders

Old streams Flow slowly through a ​ (a)   flat ​ (b)  

​ (c)   sediment is found in the floodplain

• wide
• floodplain
• Smallest

A Floodplain is an area of ​ (a)   ground to a river, formed mainly of river ​ (b)   and subject to ​ (c)   .

• low-lying
• sediments
• flooding

A ​ (a)   load-smaller sediments that are suspended or ​ (b)   in the water

Dissolved load-​ (c)   material floating in the water

• Suspended
• floating
• dissolved

This stream flows quickly through the valley 

Makes a V shaped eventually deepening a widening the channel

• New stream

• Mature stream

• Old stream

The Flow is slower and STARTS to meander and curve through the valley

• New stream

• Mature stream

• Old stream

This stream flows the slowest through a wide flat floodplain

• New Stream

• Mature stream

• Old stream
