which correctly lists three different geologic features that help scientists determine the relative ages of rocks by their positions?\no magma, erosion, and intrusions\no erosion, magma, and cross - cutting relationships\no intrusions, index fossils, and magma\no index fossils, intrusions, and cross - cutting relationships

Answer

Brief Explanations:

Index fossils are used for relative - dating as they are from organisms that lived during a specific short time interval. Intrusions are younger than the rocks they cut through due to the principle of cross - cutting relationships. Cross - cutting relationships themselves are a key concept in determining relative rock ages. Magma and erosion are not features that directly determine relative ages by position in the same way as the others.

Answer:

D. index fossils, intrusions, and cross - cutting relationships
