Steno's law are laws that applied to sedimentary rocks. These laws helps in understanding sedimentary sequences.

Sedimentary rocks are derived from the deposition of pre-existing rocks in basins. In order to understand some important relationships between these rock layers, Steno's  law offer a good insight.

Steno's law are often applied when we want to do relative dating of rock layers. Some of the laws are:

  • Law of superposition of strata
  • Law of original horizontality
  • Law of lateral continuity
  • Law of inclusion
  • Law of fossil and fauna succession

These laws helps to interpret sedimentary rock sequences better.
