Answer:
c) known to have experienced numerous polarity reversals, as seen by the remnant magnetization of iron-rich minerals in rocks.
Explanation:
Paleomagnetism is the study of the Earth's magnetic fields in sediment (rocks or other archaeological material). This can be used to estimate the age of sediment (or in this case, the seafloor) because it is known that the magnetic field of Earth experienced numerous polarity reversals. This allows is to employ such sequences as a chronologic tool. Paleomagnetism has also been a significant tool in the subjects of continental drift and plate tectonics.

The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands.
Today the importance of the fur trade has diminished; it is based on pelts produced at fur farms and regulated fur-bearer trapping, but has become controversial. Animal rights organizations oppose the fur trade, citing that animals are brutally killed and sometimes skinned alive.[1] Fur has been replaced in some clothing by synthetic imitations, for example, as in ruffs on hoods of parkas.
