I don't think there are any negative effects of it being there, it is only when it is used that negative effects arise.
Possible contamination of waters and soils with uranium and radium; also radon is released.
Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment.
2. Uranium is a toxic and a radioactive chemical element.
3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.
Uranium may be a polluting agent for the atmosphere, waters, soils, vegetation.
Modern methods and more care can avoid these disadvantages.
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 is extracted from the earth by mining; after this it is processed by chemical/metallurgical procedures.
Any element is combustible we will find Uranium oxide on the earth. i.e uranium is combustible
The chemical and physical properties of uranium remain unchanged. But because uranium is a radioactive element the quantity of uranium on the earth is permanently changed due to radioactive decay.
People die from mining also the miners are ruinning our land because they are making holes in our earth From Kaitlyn and Amber
In the past uranium mining was a source of environment contamination.Now the negative effects are minor and is possible to be remedied.
Sin uranium is a metal it will form negative ions.
Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated. Any good effect for the environment.
Uranium is radioactive and toxic.
The effects seem to be mostly negative.
There are no positives of ozone depletion. The negative effects include the entering of the harmful ultraviolet radiations of the sun on the surface of earth.
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.
Uranium is formed by nuclear synthesis in supernovas and at the 'big bang'. When the earth formed Uranium became a part of the forming earth.
Of course, from minerals containing uranium.
Years after years uranium also will run out of the earth.
Yes. In the ores of the earth.
