Some ores deep in the Earth are rich in iron particles. These particles are too vulnerable to the corrosive effects of oxygen to have accumulated under the oxygenated atmosphere of today. Therefore, when the ores were deposited millions of years ago, the atmosphere must have contained less oxygen than it does today
The argument above requires which of the following assumption?
A. The iron particles were exposed to the atmosphere during the period when the ores were deposited - Correct. The conclusion
