Question 1 Report

All the following condition are favourable for the formation of delta except

presence of large lakes in ther river course

availability of adequate sediments

absence of strong current at the river mouth

presence of sheltered coast

Answer Details

A delta is a landform that is created at the mouth of a river when it flows into a standing body of water, such as a sea or an ocean. The formation of a delta requires specific conditions to be present. Therefore, the question is asking which of the following conditions is not favorable for the formation of a delta. The correct answer is "presence of large lakes in the river course." This condition is not favorable for the formation of a delta because a lake has still water, and it will not provide enough force to carry the sediments downstream to form a delta. In contrast, a river flowing into a standing body of water with enough force to transport and deposit sediments creates a delta. Therefore, options "availability of adequate sediments," "absence of strong current at the river mouth," and "presence of sheltered coast" are favorable conditions for the formation of a delta.
