Which of the following statements iscorrect?a)Point bars are also know...
Point bars are also known as meander bars. They are found on the convex side of meanders of large rivers and are sediments deposited in a linear fashion by flowing waters along the bank Meander is not a landform but is only a type of channel pattern. This is because of:
(i) Propensity of water flowing over very gentle gradients to work laterally on the banks
(ii) Unconsolidated nature of alluvial deposits making up the banks with many irregularities which can be used by water exerting pressure laterally
(iii) Coriolis force acting on the fluid water deflecting it like it deflects the wind.

Which of the following statements iscorrect?a)Point bars are also know...
Meander is a common term used to describe a bend or curve in a stream or river. It is a type of channel pattern that is characterized by a sinuous or winding course. Here are the statements and their explanations:
a) Point bars are also known as meander bars - This statement is correct. Point bars are depositional features that form on the inside of a meander bend. They are called meander bars because they are associated with meandering channels.
b) Meander is not a landform but is only a type of channel pattern - This statement is incorrect. While meander is primarily a type of channel pattern, it can also be considered a landform because it changes the shape and structure of the land over time. Meanders can carve out valleys, create oxbow lakes, and shape floodplains.
c) Meanders develop over flood and delta plains - This statement is correct. Meanders typically develop on floodplains, where the river has more space to move laterally. Deltas, which are flat or low-lying areas at the mouth of a river, can also support meandering channels.
Therefore, the correct answer is option 'D' - all of the above.
