This, he said in an interview, shows that 14,200 years ago, sea levels were rising at a rate of 14 feet per century.

During the past 4,000 years eruptions have occurred at an average rate of about 2 per century.

"Has the number of trainees per century increased or decreased in the past million years?"

This goes slowly however and sometimes only one tree per century is felled.

In some areas, the land rises at about one meter per century.

Sea level continued to rise about one foot per century.

The rivers are said to flow only about once per century.

But by 1850, the rate had risen to one Q per century.

This means that the population would be completely renewed about five times per century.
