The table below shows the four types of river erosion. What type is number 1?
1. The force of the water breaks rock particles away from the river bed
2. Rocks carried by the water wear down the river bed and banks
3. Rocks carried by the water crash into each other and wear each other down
4. Some rock – like limestone – dissolves in the water
The type of river erosion described as number 1 is “Hydraulic Action.”
Explanation: Hydraulic action occurs when the force of moving water exerts pressure on the rocks and sediments along the riverbed, causing some rock particles to be dislodged and broken away. This process contributes to the overall erosion of the riverbed and bank. If you have more questions or need further assistance, feel free to ask!
