Uranium 235 is approx. 0,7 % from the natural uranium; see the link below for the uranium supplies.
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 the heaviest naturally occurring actinide.
Uranium is a non-renewable fuel. The earth has a limited supply of this mineral. Uranium ore is mined, then refined for use in power plants. It can not be put back. The earth is not creating more uranium. As with any non-renewable fuel, we should be concern about the supply. If additional quantities are discovered, the uranium that is known to us, can increase. See related link on abundance of uranium and other minerals.
False. Most life on Earth exists in the biosphere, which includes the surface of the planet and areas where organisms can live. The ionosphere is a region in the Earth's upper atmosphere that is much higher than where most life exists.
Approximately 80% of the Earth's natural radioactivity comes from the decay of uranium, thorium, and potassium-40 in the Earth's crust.
An estimation is 50.106 t in the earth crust and oceans.

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.
Francium exists in uranium and thorium ores.
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.
Uranium mostly exists as a mineralPitch blend in mountainous rocks it is extracted in any country under the strict supervision of government.
Yes. In the ores of the earth.
in earth
Yes, uranium is a natural chemical element.
