Answer:
The hypothesis can be made as follows:
' If there are less or no estuaries in a river, then there will be more erosion at the shorelines.'
A hypothesis is a tentative statement which can either be supported through experiments or proven to be wrong.
In the following scenario, we can conduct experiments by taking into observation those rivers which have estuaries and those which do not have estuaries. We can then compare the erosion of the shorelines of the rivers to validate our hypothesis.
