Q:

Statement I :

Incised meanders are formed in the mature stage of a river.

Statement II :

Incised meanders are characterized by rejuvenation and upliftment of land.

A) Both the statements are individually true and Statement II is the correct explanation of Statement I B) Both the statements are individually true but Statement II is not the correct explanation of Statement I
C) Statement I is true but Statement II is false D) Statement I is false but Statement II is true  
 
Answer & Explanation Answer: D) Statement I is false but Statement II is true  

Explanation:

Rejuvenation occurs when the river’s base level falls (i.e. when sea level falls). This can be a consequence of either a fall in the amount of sea water or the land rising. Incised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to down cut. Hence, 2nd statement is correct.

There are two types of incised meanders, entrenched meanders and ingrown meanders.As they are products of rejuvenation, they are not formed in mature stage of a river
