9. Mira had a hard time understanding how greenhouse gases and climate change are related. Her friend Lucius wanted to explain the concepts to her. Help Lucius write an explanation for Mira by completing this paragraph.(6 points) Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. Substances called Response area are important because they act as a blanket to keep Response area in our atmosphere. However, human activities can Response area the concentrations of greenhouse gases in the atmosphere so much that they keep too much thermal energy in the atmosphere. This causes global temperatures to Response area, which is a phenomenon called Response area. This phenomenon is one contributing factor to changes in long-term weather patterns known as Response area.
