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 deposited
- Then an intrusion A occurred and terminated at B
- Layers 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.

Placemark takes you to an ENE view of a steep, seaward-sloping face behind the flat, coastal sea terrace on which people have built homes. The place mark is positioned on the most recent, active mudslide, which is the infamous La Conchita mudslide. Why do you think this mudslide occurred?
On January 10, 2005, a landslide struck the community of La Conchita in Ventura County, California, destroying or seriously damaging 36 houses and killing 10 people.
the area has little vegetation to hold the soil
the area could have been undercut by the road halfway up the slope
the sea terrace on which the houses sit has over-steepened the cliff
