23、 top will be separated from the anoxic conditions at the base,”Fraser explained.Conserved within these oxygen-free basins,the matter maintains compounds that finally make it useful as an energy source for millions of years in the future.8.Why didRussiaplant a national flag onto the Lomonosov Ridge?A
