Question

In which situations is the principle of cross-cutting relationships useful in determining relative age? Check all that apply. A fault breaks through sedimentary layers. Sedimentary layers form and then are tilted. Igneous rock forms between sedimentary layers. Sedimentary layers form over millions of years in a lake bottom. Lava flows form on top of one another from several eruptions over time.

Answer 1

The right options are;

A. A fault breaks through sedimentary layers.

B. Sedimentary layers form and then are tilted.

C. Igneous rock forms between sedimentary layers

The principle of cross-cutting relationships is a relative dating method that was first developed by Nicholas Steno in 1669. The principle states that the geologic structure which cuts another is the younger of the two structures. There are many major types of cross cutting relationships which include; geomorphological relationships, intrusional relationships, sedimentological relationship, structural relationships, and paleontological relationships.

Answer 2

The correct answers are.

A. A fault breaks through sedimentary layers.

B. Sedimentary layers form and then are tilted.

C. Igneous rock forms between sedimentary layers.
