The percent of Earth's atmosphere that carbon dioxide gas makes up is less than 1 percent.
To determine the percent of Earth's atmosphere that carbon dioxide (CO2) gas makes up, we need to look up the information. One reliable source of information is NASA's Earth Observatory website.
Step 1: Open a web browser and navigate to the NASA Earth Observatory website (www.earthobservatory.nasa.gov).
Step 2: Once on the website, use the search function or browse for information related to Earth's atmosphere or the composition of Earth's atmosphere.
Step 3: Look for specific data or statistics related to the percentage of carbon dioxide in Earth's atmosphere. This could be presented in various forms such as a percentage or a concentration in parts per million (ppm).
Step 4: Based on the information obtained, determine the most accurate and up-to-date answer to the question.
Please note that the percentages provided by the answer choices are only hypothetical options and may not reflect the actual representation of carbon dioxide in Earth's atmosphere.
