Question

which statement about how geologists study the age of rock layers is true​

Answer 1

• Answer:

The principle of original horizontality provides the basis for the law of superposition.

Explanation:

The principle horizontal principle explains that all strata were originally horizontal in sedimentary rocks.

This is a correct answer

hope this helps!

Answer 2

Answer:

Option-(C):It is the best option to choose from the given four.

Explanation:

We have the following explanation to the given option selected by us;

• Law of superposition- It states that the younger layers of the rock sediments occur on top of the earth surface while, the older layers occur beneath them with a given sequence if there was no disturbance occurred in the sequence formation.
• Principle of original horizontally: According to the following principle the rock sediments or layers of the earth are formed starting horizontally, as the folded and tilted strata are analyzed through by this principle.

As, the geologist do the analyses of earths layer and they measured the age and the position of the sediments present in the earth layers, to find its properties.
