meters or more.
Thermohaline circulation produces great vertical currents' hat flow from the
surface to the ocean bottom and .....

The Age Of The Earth

As it turns out, this is what scientists believe to be.
The assumption that the earth is 4.5 billion years old has raised doubts in the minds of some skeptics who question the accuracy of the data used in radiometric dating! They claim that without knowing the exact amount of Uranium in .....

certain types of lightning, the panel noted.

scientists in Sweden and Norway first believed that acidic rain may be causing
