Answer:

Principle of Superposition and Principle of Cross-cutting relationship

Explanation:

According to the law of superposition, the rock layers that are present at the base of a rock sequence are the oldest rocks as they were deposited a long time back, and those layers that are present at the apex are the youngest rocks and were deposited recently.

According to the law of cross-cutting relationships, the geological features (igneous intrusive bodies) such as d(i)kes, sills, batholiths, laccoliths, lopoliths are younger than the rocks that are being cut. This provides the relative age of the features.

In the given condition, as Bary says that the lowest portion of the building is constructed earlier than the upper portion, he refers to the principle of superposition.

And when he says about the cracks that are formed in the walls, he referred to the principle of cross-cutting relationship.

Answer:

1: Before

2: Superposition

3: Younger Than

4: Cross-Cutting Relationships
