Rocks with an imprint of Earth's magnetic code contain
A)the rock's polarity, magnetic-pole direction, and the altitude of the magnetic pole.

C)polarity, latitude of origin, and fossils indicating the age of the rock.
D)all of the above

Question

Quizplus · Accepted Answer

Rocks with an imprint of Earth's magnetic code can show the rock's polarity (whether it was oriented toward the north or south magnetic pole at the time of its formation), the latitude of origin (which can be inferred from the angle of the magnetic minerals within the rock), and the direction of the magnetic pole at the time of formation. This information helps geologists understand past movements of Earth's tectonic plates and the history of Earth's magnetic field.
