Construct a model of the carbon cycle that explains why the carbon dioxide levels are increasing over time in Mauna Loa. Be sure to use quantitative data from the lab to support your explanation. You may create two or more models to illustrate the changes over time.​



Answer :

The carbon dioxide levels in Mauna Loa are rising over time because the majority of fossil fuel CO2 is released in the Northern Hemisphere.

An average of 280 ppm CO2 was present in the atmosphere before 1800. The last persistent increase in CO2 on Earth occurred between 17,000 and 11,000 years ago when levels rose by 80 ppm. The rate of growth today is 200 times faster.

The most recent eruptions of Mauna Loa, a volcano, were in 1950, 1975, and 1984. It occasionally releases sulfur dioxide (SO2) and carbon dioxide (CO2) through fissures at the peak in the intervals between eruptions.

Human actions, particularly the combustion of fossil fuels and the clearance of forests for agriculture, are causing CO2 to build up in the atmosphere. You will also discover how the rate of CO2 accumulation in the atmosphere is substantially influenced by natural processes on land and in the water.

Therefore, since the vast majority of CO2 from fossil fuels is released in the Northern Hemisphere, we can draw the conclusion that the quantities of carbon dioxide in Mauna Loa are increasing over time.
