Uranium decay heat deep in the earth's core and lower mantle drives convection currents. In the core this produces a dynamo and maintains earth's strong magnetic field. In the mantle it drives plate tectonics and may be responsible for hot spot volcanos (like Hawaii and Yellowstone).
What else can I help you with?
Uranium-235 and uranium-238 are different?
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
Why is it important to know whether a resource is renewable or nonrenewable?
1.) Because it determines whether or not investing in this particular resource will be practical in the long term. For example, uranium is NOT a renewable resource, which is why fission nuclear energy which uses uranium won't be around too long if only Earth's uranium is used. 2.) Because your homework depends on it.
What effect did photosynthetic cyanobacteria have on earth's environment?
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
Where are the most recent earthquakes occurring?
I think it's a direct effect of the poles shifting on the planet earth. I think it's a direct effect of the poles shifting on the planet earth.
How do you separate uranium from water?
What do you mean. Uranium is not soluble in water.
Is Earth's mantle composed of uranium?
Uranium is only one of the components of the earth mantle.
Was uranium created with the earth and will it run out?
Uranium was created in the early stages of the universe by stellar nucleosynthesis. Uranium cannot be lost from the earth.
Is uranium extraced from the earth?
Of course, from minerals containing uranium.
Is uranium sustainable?
Years after years uranium also will run out of the earth.
Was uranium formed in 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.
Is uranium found on earth?
Yes. In the ores of the earth.
Is Uranium found in air water or earth?
in earth
Does uranium exist naturally in the earth?
Yes, uranium is a natural chemical element.
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
How uranium effect your environment?
Uranium undergoes radioactive decay and emits alpha particles which can damage tissue.
Why wasn't uranium formed when the earth was formed?
Uranium is a heavy element that is primarily produced through supernova nucleosynthesis in the universe. The Earth's formation occurred from the remnants of earlier supernovae, but not all elements were present in the same abundance in the material that formed the Earth. Uranium's scarcity in the Earth's crust is due to its low abundance in the primordial material that coalesced to form the planet.
This element is mostly found as a with a compound with uranium?
Uranium is found in the earth only in the form of compounds. Uranium is present in cca. 200 minerals.
