Directions: Select the correct answer from each drop-down menu. Mr. Jones is a geographical scientist. He researches the rise in the carbon dioxide level due to increasing pollution. In 2003, the average carbon dioxide level was about 223 billion metric tons, and in 2008, it was about 1,350 billion metric tons. Between 2003 and 2008, Mr. Jones found the rise to be approximately

To find the rise in carbon dioxide levels between 2003 and 2008, we can subtract the 2003 level from the 2008 level. 2008 level: 1,350 billion metric tons 2003 level: 223 billion metric tons Rise = 1,350 billion metric tons - 223 billion metric tons Rise = 1,127 billion metric tons So, the rise in carbon dioxide levels between 2003 and 2008 was approximately **1,127 billion metric tons**.
