Question

Background:<br/>Scientists have been monitoring atmospheric CO2 levels

for several decades. The graph below shows continuous measurements made from 1958 to 2020. The CO2 levels on the graph are in units of parts per million (1 particle of a substance in 1 million other particles). Study the graph and Figure 2 and answer the questions below.
Figure 1: CO2 increase with time (this is also called the Keeling curve).
Figure 2: Sources and sinks of carbon.
In the year 2000, there were about 730 gigatons of carbon in the atmosphere, 2,000 gigatons in Vegetations and Soils, and 38,000 gigatons of carbon in the Oceans.


Data:
Measurement indicate that:
1. The average increase in atmospheric CO2 is 11 gigatons per year (11 x 109 tons or about 1013 kg/year). 1 gigaton = 109 tons, 1 ton = 1000 kg.
2. There are 12 gigatons of elemental carbon for every 44 gigatons of molecular CO2 (the rest is oxygen).
Note: complete the sections below, and copy-paste them into your final report.


Please show your calculations for the questions below.
Part of the evaluation will be based on following systematic, organized, problem-solving steps. This involves using the correct equation, rearranging it to find the quantity of interest, substituting the known values, and then writing the final answer with the correct units. Please use scientific notation for your final answer. For example: 1,000,000,000 tons = 1.0 x 109 tons = 1.0 gigatons = 1.0 Gt.



Questions
1. Look at Figure 2 above and list the sources that cause carbon (CO2) to increase in the atmosphere. These sources are the ones with arrows pointing up to the sky. For example, vegetation adds 119 gigatons of carbon every year. The first row has been completed as an example.
