Human activity, such as the burning of coal and oil, refining petroleum in factories has impacted which of the following A) carbon cycle
B) water cycle
C) nitrogen cycle
D) oxygen cycle

carbon cycle

Explanation:

Carbon is an essential element in the bodies of living organisms. It is also economically important to modern humans, in the form of fossil fuels.

Carbon dioxide—\text {CO}_2CO

Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.

Some human activities, such as burning of fossil fuels and deforestation, increase atmospheric \text{CO}_2CO

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
