Question

q 11 what is the primary geologic importance of the 4 stratigraphic principles (superposition, original horizontality, cross - cutting relationships and )? they help determine the exact numerical age of rocks and fossils using radiometric dating techniques. they provide a framework for determining the the relative ages of rock layers and geological events, allowing scientists to reconstruct earths sequences and correlate rock layers across vast distances. they are exclusively used to locate hydrocarbon deposits and other natural resources. they explain the physical and chemical composition of different rock types and how they form.

Explanation:

The principles of superposition (older layers at the bottom), original horizontality (layers form horizontally), cross - cutting relationships (a feature that cuts another is younger) are used to establish the relative order of rock layers and geological events. Radiometric dating (for exact numerical age) is a different method. Locating resources is a secondary application. Explaining rock composition is about petrology, not stratigraphic principles.

Answer:

They provide a framework for determining the the relative ages of rock layers and geological events, allowing scientists to reconstruct earths sequences and correlate rock layers across vast distances.
