12 Questions
What happens to the river's flow as it encounters stones and other obstructions in its course?
The river's flow starts to twist and turn, resulting in areas of slower and faster water movement.
What is the difference in erosion and deposition between the outside and inside bends of a meander?
The outside bends experience erosion due to faster water movement, while the inside bends experience deposition due to slower water movement.
What is the result of continual erosion and deposition on the neck of a meander?
The neck of the meander becomes narrower, eventually leading to a cut-off during a flood.
What happens to the meander after the river cuts through its neck?
The meander is abandoned, and new deposition seals off its ends, forming an oxbow lake.
Where are deltas typically found, and what is their characteristic feature?
Deltas are found at the mouth of a river, as it enters a sea or lake, and are characterized by a deposit of sediment.
What is the characteristic of a river's flow that leads to the formation of a meander?
The river's flow is faster on the outside bends and slower on the inside bends.
What is the primary reason for the formation of a river cliff?
Erosion on the outside bends due to faster water movement
What is the eventual fate of a meander after the river cuts through its neck?
It is abandoned and becomes an oxbow lake
What is the primary process responsible for the lateral erosion of a river?
Corrasion and corrosion
What is the characteristic feature of a delta?
A network of distributaries
What happens to the river's flow when it encounters stones and other obstructions?
It changes direction and forms a meander
What is the ultimate fate of an oxbow lake?
It eventually dries up
Learn about the formation of meanders and ox-bow lakes in the middle course of a river. Understand how water movement and erosion shape the river's path and create unique features. Test your knowledge of river dynamics and geological processes!
