bottom of the ‘cliff’.
Soon, the harder rock won’t have any support and it breaks
off.

Question 5
How are Meanders and Oxbow lakes
related?
Meanders and oxbow lakes
are both types of rivers.
When the materials from a meander is deposited onto the
banks, it slowly starts to get more
round until the loop that was once part
of the meander gets cut off.
Over time, what used to be an
oxbow lake becomes a meander
because of erosion.
The shape of a Meander and an oxbow lake is so
similar, it sometimes gets
mixed up.
