Answer:
d. the relative age of these rock layers
Explanation:
Principle of superposition -
It is the form of relative dating , where the relative age of the rocks are determined .
It is on of the important principle for the study of geological stratigraphy .
According to the principle of superposition , the bottom most layer of the strata is one of the oldest one , and the top most is the most recent one .
Hence , the relative age of the rock can easily be determined by using this principle of superposition .

Explanation:
Answer:
The correct answer is: X is nitrogen dioxide, and Y is a metal oxide
Explanation:
Combustion of compound of containing nitrogen and metal will give nitrogen dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.
The general equation is given as:
Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
