Question

what geologic term or phrase explains why the top of the stratum in a section of rock is the youngest

Answer 1

superposition

Step-by-step explanation:

The geologic term or principle that explains why the top of the stratum in a section of rock is the youngest is the word superposition.

This term is derived from the principle of superposition of strata which states that "in an undeformed sequence of strata, the oldest bed is at the bottom and the youngest is at the top".

Sedimentary rocks succeed on another in a determined way.

• When we use the term superposition, we simply imply that the beds are stacked over another.
