An estimation is 50.106 t in the earth crust and oceans.
It would require an immense amount of uranium, far beyond what is accessible on Earth, to detonate the planet. The idea of destroying Earth with uranium or any other material is simply not feasible with current technology.
Uranium is only one of the components of the earth mantle.
Uranium was created in the early stages of the universe by stellar nucleosynthesis. Uranium cannot be lost from the earth.
Of course, from minerals containing uranium.
Years after years uranium also will run out of the earth.
Uranium is not made on the earth. Uranium and the majority of the other elements (excepting H, He, Be, Li, transuranium elements) are formed after the big-bang (creation of the universe) by stellar nucleosynthesis.
Yes. In the ores of the earth.
in earth
Yes, uranium is a natural chemical element.
Uranium is the heaviest naturally occurring actinide.
Uranium has the greater density. Note that "1 g" is irrelevant - the density of a substance doesn't depend on how much of the substance you take.
It is estimated that Earth possesses about 40 million metric tons of uranium reserves. The metal is primarily found in rocks, seawater, and soil, with the largest deposits located in Australia, Kazakhstan, and Canada. While uranium is a finite resource, current levels of production and consumption are sustainable for the foreseeable future.
