Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The Walther’s Law of Facies was introduced by the German geologist Johannes Walther (1860–1937) as an important geological principle, after the establishment of the concept of “facies,” one of the foundations of modern stratigraphy. Walther’s Law states that any vertical progression of facies is the result of a succession of depositional environments that are laterally juxtaposed to each other. Conversely, it states that when a depositional environment "migrates" laterally, sediments of one depositional environment come to lie on top of another.
