River Erosion and Transport Processes

All rivers flow to an _____________________. 

• lake 
• ocean
• mountain
• pond

what is source?

• The end point of the river

• The mid-point of the river

• the starting point of the river

• All of the above

what is precipitation?

• Water falling from the sky

• Raindrops dropping from the sky

• Water dropping from the sky

• Raindrops falling from the sky

• all of the above

Corrasion/Abrasion is...

• The power of the water hitting off the rocks

• The chemicals in the water slowly dissolving the rocks

• The air being compressed in a fault or weakness, expanding and enlarging it

• The material (load) of the river hitting the river bed and scraping off more rock and sediment

Which is NOT a method of transportation?

• Abrasion
• Saltation
• Traction
• Suspension

"This is where plants, trees, or buildings collect the precipitation" What am I?

• Interception
• Infiltration
• Percolation
• Surface runoff

"Where the water filters into the ground and into the tiny pores in the soil" What am I?

• Infiltration
• Percolation
• Precipitation
• Interception

Sand and stones scraping the bed and banks of the river wearing them away is:

• Transport

• Hydraulic Action

• Abrasion

• Solution

Rocks and stones knocking together to wear each other away is called:

• Hydraulic Action

• Attrition

• Solution

• Abrasion

Water being forced into cracks in the bank and over time breaks the bank up, causing it to fall is:

• Abrasion

• Plucking

• Bedload

• Hydraulic Action
