Students: Note that Assignment #15 is up on Google Classroom awaiting your skills. NOTE THAT ANOTHER ATTACHMENT HAS BEEN ADDED FOR THE VENN DIAGRAM THAT YOU CAN COPY AND COMPLETE AND SUBMIT. <\/strong><\/p>\n\n\n\n

You are to complete the Venn Diagram on the second page of the attachment that the classroom teacher has already started it for you. Double click on it, and it should open up and as you research your material, you will be able to fill in the appropriate information for comparing and contrasting three of the inner planets, namely, Venus, Earth, and Mars. <\/p>\n\n\n\n

Once you are done, you will reinforce the topic, as you have normally done in class, and you will synthesize an answer to the lesson question.<\/p>\n\n\n\n

On a lighter note, here is the answer key for the short answers on the background information of the lesson:<\/em><\/strong><\/p>\n\n\n\n

  1. Define the greenhouse effect.<\/li><\/ol>\n\n\n\n

    The greenhouse effect <\/strong>is a part of the greenhouse system, the characteristic absorption of thermal energy by greenhouse gases<\/strong> in the atmosphere (the mixture of gases that surround the planet) and re-radiation back towards Earth\u2019s surface. <\/p>\n\n\n\n

    1. What role and<\/em> outcome do the <\/em>concentration of the greenhouse gases in the atmosphere play?<\/li><\/ol>\n\n\n\n

      Greenhouse gases, such as carbon dioxide, are those that absorb incoming thermal energy and reradiate energy in all directions as thermal energy. When Earth’s atmosphere has higher concentrations of greenhouse gases, the mean surface temperature of the Earth will be higher.<\/p>\n\n\n\n

      1. Reflecting back on system models, what role do these models play here?<\/li><\/ol>\n\n\n\n

        System models can be used to represent the greenhouse effect systems and its interactions\u2014such as inputs, processes and outputs\u2014and energy and matter flows within the system.<\/p>\n\n\n\n

        1. Earth is considered to be a closed system<\/em>. What is so special about that?<\/li><\/ol>\n\n\n\n

          Through using a model, one can input<\/strong> various greenhouse gas concentrations and observe from the surface temperature output<\/strong> that increasing or decreasing greenhouse gases directly increases or decreases Earth\u2019s surface temperature. <\/p>\n\n\n\n

          1. What is meant by the mean surface temperature and what contributes to it?<\/li><\/ol>\n\n\n\n

            Mean (average) surface temperature<\/strong> is a measure of the amount of thermal energy present and is dependent in part on the concentration of greenhouse gases in the atmosphere.  <\/p>\n\n\n\n

            OR<\/p>\n\n\n\n

            Earth\u2019s mean surface temperature<\/strong> is the average over the whole planet, from the equator to the poles, all year round – currently this temperature is roughly 15o<\/sup>C or 60o<\/sup>F. This temperature depends partially on the interaction of sunlight (visible electromagnetic energy) and gases in the atmosphere.<\/p>\n\n\n\n

            1. How are gas molecules related to the energy of the sun?<\/li><\/ol>\n\n\n\n

              Gas molecules in the atmosphere allow incoming solar radiation to pass through them without absorbing energy.<\/p>\n\n\n\n

              1. What is the indication of the internal energy of an object that results in its temperature?<\/li><\/ol>\n\n\n\n

                Thermal energy<\/strong>, which can be represented by infrared photons, <\/strong>is the internal energy of an object due to its temperature.<\/p>\n\n\n\n

                1. Why is the majority of the energy able to pass through the atmospheric gases?<\/li><\/ol>\n\n\n\n

                  The primary components of Earth\u2019s atmosphere, nitrogen (78%) and oxygen (20%), are gas molecules with rigid structures that do not vibrate when hit with thermal energy; therefore, most of the energy passes through them.<\/p>\n\n\n\n

                  1. How are greenhouse gases different from atmospheric gases?<\/li><\/ol>\n\n\n\n

                    Greenhouse gases such as carbon dioxide (CO2<\/sub>), methane (CH4<\/sub>), and nitrous oxide (N2<\/sub>O) possess a vitally different molecular property: Their atoms vibrate when they absorb thermal energy. The vibrating gas molecules then re-radiate thermal energy in all directions, including back down to Earth.<\/p>\n\n\n\n

                    1. How is the greenhouse effect created? Explain your response.<\/li><\/ol>\n\n\n\n

                      The process of energy absorption and re-radiation back towards Earth\u2019s surface creates the greenhouse effect, based on the idea of how the glass walls of a greenhouse maintain a higher concentration of thermal energy within the greenhouse.<\/p>\n","protected":false},"excerpt":{"rendered":"
