Question
Under annual reports 2008 pertaining to A search for primordial water from deep in the Earth's mantle How do you tell the difference between subducted water from tectonic plate shift and primordial water? Is their any truth that radioactive materials in the earths core are helping to keep the earth moleton
I don’t know what you mean by “primordial water”. Much of the water on Earth has accumulated from the impacts of ice-rich comets and asteroids, and this water is constantly recycled through the atmosphere, oceans, and chemical adsorption in rocks. And yes, the Earth’s interior is kept warm from radioactive materials. But these are found primarily in the Earth’s mantle, not the core. See the Wikipedia article on Structure of the Earth for details.
