Answer 1

Answer:

Layer B is older than intrusion A

Intrusion A is older than layers C, D, and E.

Layer B is older than layers C, D, and E.

Explanation:

The laws of biostratigraphy can be applied to this lithological section in order to ascertain the relative ages of the beds.

Some of these laws that are applicable to this problem are:

Principle of superposition of strata : the oldest layer is always at the bottom of sequence while the youngest is on top in an undisturbed rock sequence. Law of cross-cutting: when faults and fractures cuts through a rock sequence, they are younger than the rock they cross through. Law of intrusions: Intrusions are younger than the rock layers they cut through

The geologic history of the beds here can be interpreted as thus:

Lithology B was first depositedThen an intrusion A occurred and terminated at BLayers C, D and E were then deposited.

The oldest layer here is B followed by the intrusion A and successful deposition of C, D and E in that order.

Answer 2

Answers: Layer B is older than intrusion A , intrusion A is older than layers C, D, and E, and layer B is older than layers C, D, and E.
