Kui pinnases on väga vähe koobaltit, siis kasvavad taimed ei saa seda omastada, ning neist toituvad loomad kannatavad koobaltipuuduse all, mis on nende jaoks hädavajalik. Samas kaevanduste ja sulatustehaste lähedal võib olla ka väga kõrge koobalti kontsentratsioon, mis samuti võib loomades tekitada terviseprobleeme[6]. 7 Kasutatud kirjandus [1] ,,COBALT AND INORGANIC COBALT COMPOUNDS" [Võrgumaterjal] Available: http://www.inchem.org/documents/cicads/cicads/cicad69.htm#2.0 [Kasutatud 06. jaanuar, 2018] [2] ,,Cobalt" [Võrgumaterjal] Available: https://en.wikipedia.org/wiki/Cobalt [Kasutatud 07. jaanuar, 2018] [3] ,,10 Top Cobalt-mining Countries by Production" [Võrgumaterjal] Available: https://investingnews.com/daily/resource-investing/critical-metals-investing/cobalt- investing/top-cobalt-producing-countries-congo-china-canada-russia-australia/ [Kasutatud 07

Still more luminous than a billion suns, the supernova outshone the combined light from all the stars in its home galaxy, glowing white-hot from the radioactive decay of unstable nickel atoms forged in the explosion. Gal-Yam pointed to a computer screen showing a squiggly line--the glow broken down into its component colors, or wavelengths. Each dip in the line represented a wavelength of light absorbed by a different element--silicon, cobalt, calcium, iron--in the debris of the star. Destruction and creation were conjoined on the screen. The elements revealed there, like those from countless earlier supernovas, will eventually find their way into new stars and perhaps new planets, Gal-Yam said. He added: "I'm just really happy to be observing this." The star had begun its race to destruction long before that night on Palomar, when it began to lose a lifelong fight against gravity
were of Scottish origin. Today, there are almost as many Scots Canadians as there are people in the whole of Scotland. 12. Which important minerals are found in Alberta? Canada is abundant in many mineral resources — mined in every province and territory — and a world leader in the production of potash, aluminum, nickel, salt, sulphur and uranium, among others. Today, Canada is the leading producer of potash and is estimated to rank in the top five global producers of aluminum, diamonds, cobalt, nickel, platinum, tungsten, uranium and sulphur Alberta is the country's largest producer of crude oil and gas products (especially natural gas) 13. Which is the main crop grown in the Prairie Provinces? The main crop is wheat, but barley, brassica, canola, and oats are also cultivated. 14. The political and language situation in Quebec. Why do the Quebecois want to be called a distinct society? French is the official language of Quebec 15. What is Nunavut?
