Why does the sea floor have a striped pattern of magnetic anomalies that is symmetric with respect to the mid-ocean ridge? Choose all that apply. View Available Hint(s) The igneous rock of the ocean floor preserves Earth's existing magnetic field as the rock cools. Polar reversals cause existing ocean crust to remagnetize. The polarity of Earth's magnetic field experiences reversals. The ocean floor is spreading apart and new sea floor is forming. Marine organisms that live on the sea floor have caused this pattern.

What piece of evidence supports Wegener's hypothesis of continental drift? View Available Hint(s) Rocks of varying ages found in mountain chains separated by the Atlantic Ocean indicate that they formed at different times in history.. Coal deposits that form in tropical swamps are absent from continents near the poles.. Records of glacial masses in the tropics indicate a worldwide ice age.
