BBE Final Exam 2001 Actual Questions and Answers with complete solutions In the video we saw that the carbon cycle is balanced with some sinks and some sources of carbon. The two primary sources of anthropogenic carbon are fossil fuel combustion and land use changes. Indicate which are the three main carbon sinks for this anthropogenic carbon. - Answer ️️ -The three primary sinks of carbon are oceans, land and vegetation, and the atmosphere. Interesting also that CEMENT application is the third biggest source of CO2e. True or False? Clearing forests to plant agricultural crops results in an increase in atmospheric carbon dioxide. - Answer ️️ -True Early in the video lecture, Dr. Matsumoto talked about seasonal fluctuations in CO2 (This is very easy to see when you look at atmospheric concentrations of CO2 graphs.) What are these seasonal fluctuations due to? - Answer ️️ -Photosynthesis and respiration or decomposition Dr. John Baker in the video talked about how work is ongoing on ways to improve carbon sequestration as part of agricultural practices. What is meant by the term "carbon sequestration"? - Answer ️️ -Capturing of atmospheric carbon by plants, soils, and oceans. True or False.

This serves a purpose, but because of all of the overlap it is really hard to break it down this way. Some think a better way to think about "Whose carbon is it?" is to frame the issue as _______________. - Answer ️️ -Consumer demand In the briefing paper we learned about Carbon Dioxide Equivalents. The main point about carbon dioxide equivalents is that gases trap different amounts of energy per molecule of gas, and so we have normalized the data into something called Carbon Dioxide Equivalents. It is also referred to as the Global Warming Potential (GWP) of t
