Question

When do experts expect the extraction of iron will reach its peak?​

Answer 1

Answer: over 1.8 billion years ago

Explanation: early all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.
