barry is applying the principles of relative dating to a building that has been constructed. analyzing a section of the building, barry

says that the lowest part of the section must have been constructed

the parts above it were constructed. he

bases this conclusion on the principle of

. also, looking at a crack forming in the building wall, he says

that the crack must be

the wall. barry used the principle of

to arrive at this

conclusion.

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.

1: Before

2: Superposition

3: Younger Than

4: Cross-Cutting Relationships

Explanation:

I took the test and got it right.

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
