Homework Answers
Carbon dioxide is an important component of the atmosphere. Carbon dioxide is released through natural processes such as respiration. The released carbon dioxide is used up by the plant to produce the food by a process called photosynthesis. However through human activities such as deforestation, burning fossil fuels, green house emissions have increased the atmospheric co2 concentration. That is leading to climate change.

The increase in carbon dioxide (CO2) in the atmosphere is a major cause of global warming. Using data obtained by Charles David Keeling, professor at Scripps Institution of Oceanography, the average amount of CO2 in the atmosphere from 1958 through 2016 is approximated by A(t) = 0.0124 14t + 0.7485t + 313.9 (1 59) where A(t) is measured in parts per million volume (ppmv) and t in years, with t-1 corresponding to 1958.1 Find the average rate of increase of...

Scientists predict that as atmospheric carbon dioxide levels increase, the pH of the oceans will drop. What is the best explanation for this hypothesis? As the pH of the ocean increases, more carbon dioxide is released into the atmosphere As the pH of the ocean decreases, more carbon dioxide is released into the atmosphere O Carbon dioxide combines with water to form a base Carbon dioxide combines with water to form an acid As the oceans warm, more water is...
