Question

sources of carbon dioxide in the atmosphere
carbon dioxide is one of the greenhouse gases that helps to keep earth warm enough to support life. however, an increase in the amount of carbon dioxide in the atmosphere increases the temperature. an investigation was done to compare the natural and human - made sources of carbon dioxide in the atmosphere. two tables were created to display the results.
human - made sources of carbon dioxide
source\tapproximate percentage
electricity and heat generation\t41
transportation\t22
industry\t20
residential\t7
other\t11
total\t100
directions: read the passage, analyze the tables and answer the question below.
which question can best be generated based on this research?
do plants produce more carbon dioxide than animals?
do humans release more carbon dioxide into the atmosphere than natural phenomena?
does carbon dioxide in the atmosphere cause rainy weather conditions?
is carbon dioxide in the atmosphere helpful or harmful?

Explanation:

The research focuses on comparing natural and human - made sources of carbon dioxide in the atmosphere. The table shows human - made sources. The question about whether humans release more carbon dioxide than natural phenomena directly relates to the research aim of comparing the two types of sources.

Answer:

Do humans release more carbon dioxide into the atmosphere than natural phenomena?
