Erosion Transport And Depostion

Question 1

What is the first stage of erosion

Answer 1

Sand and stones scrape the bed and banks causing more to fall off this is called abrasion

Question 2

What is the second stage of erosion

Answer 2

Rock and stones knock each other causing them to wear each other away, this is called attrition

Question 3

What is the third stage of erosion

Answer 3

In a fast flowing river,water gets forced into cracks in the bank causing it to break overtime
This is called hydraulic action

Question 4

What is the fourth stage of erosion

Answer 4

Water also dissolves soluble minerals from the bed and banks, this helps break them up
This is called solution

Question 5

What is the first stage of transportation

Answer 5

Dissolved material is carried along as solution which is invisible to the naked eye

Question 6

What is the second stage of transportation

Answer 6

Small light particles of rock and soil are carried along as suspension . They makes the water look cloudy or dirty

Question 7

What is the third stage of transportation

Answer 7

Heavy material like rocks are collected at the bottom of the river and rolled along this is called bedload while sand and other soluble stuff flows through the water
