According to the law of conservation of matter, matter is never created or destroyed. it only changes form as is evident in the water cycle. but what about the other geochemical cycles? nutrients circulate throughout the environment in complex cycles called biogeochemical cycles, or nutrient cycles. carbon, oxygen, phosphorus, and nitrogen are nutrients that cycle through all of earth’s spheres and organisms.
humans shift carbon to the atmosphere in many ways. and because of the law of conservation of matter, there it stays as the primary greenhouse gas. by extracting fossil fuels, we remove carbon from storage in the lithosphere. by burning those fossil fuels, we move carbon dioxide into the atmosphere. all but one human activity increases the amount of atmospheric carbon.
a) deforestation
b) planting cover crops
c) industrial manufacturing
d) transportation/locomotion

Planting cover crops

Explanation: Planting of the cover crops actually stores the carbon in the soil also known as "Carbon Sequestration" (Sequestration occurs when CO2 is removed from the atmosphere and stored in the soil.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
