Questions & Step-by-Step Solutions
Which gas is primarily responsible for global warming?
Step 1: Understand what global warming is. It is the increase in Earth's average temperature due to human activities.
Step 2: Learn about greenhouse gases. These are gases that trap heat in the atmosphere.
Step 3: Identify the main greenhouse gases. The most common ones are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
Step 4: Focus on carbon dioxide. It is released when we burn fossil fuels like coal, oil, and gas.
Step 5: Recognize that carbon dioxide stays in the atmosphere for a long time, making it very effective at trapping heat.
Step 6: Conclude that carbon dioxide is the primary gas responsible for global warming because it is the most abundant greenhouse gas produced by human activities.
