What is meant by Walthers Law in science?

Question

Okay I need to know how exactly Walthers Law also relates to depositional environments? 3rdly What are two examples of the law in action. and lastly What does Walther’s law say about incomplete cycles?

Answer 1

From the link below:

Walther's Law of Facies, named after the geologist Johannes Walther, states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when a depositional environment "migrates" laterally, sediments of one depositional environment come to lie on top of another.

A classic example of this law is the vertical stratigraphic succession that typifies marine trangressions and regressions. However, the law is not applicable where the contact between different lithologies is non-conformable (i.e. sedimentation was not continuous), or in instances of rapid environmental change where non-adjacent environments may replace one another.
