Vocabulary: atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis Prior Knowledge Questions (Do these BEFORE... using the Gizmo.) In the process of photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil. Using the energy of sunlight, plants build molecules of glucose (C6H12O6) and oxygen (O2). 1. How do plants on Earth affect the amount of carbon in Earth’s atmosphere? Plants absorb the Carbon in the air and turn it into oxygen. This means the Carbon gets taken out. 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’s atmosphere? They use a process called respiration to produce more carbon. Gizmo Warm-up The Carbon Cycle Gizmo™ allows you to follow the many paths an atom of carbon can take through Earth’s systems. To begin, notice the black carbon atom in the Atmospheric CO2 area, highlighted in yellow. The glowing blue areas represent possible locations the carbon atom could go next. 1. From Earth’s atmosphere, where can the carbon atom go next? It can go to the ocean, land plants, or exposed rock. 2. Click on Land plants and read the description. How did the carbon atom get from the atmosphere to a plant? It got there by photosynethesis This study source was downloaded by 100000830772748 from CourseHero.com on 05-06-2022 14:20:10 GMT -05:00 https://www.coursehero.com/file/40590762/CarbonCyclertf/ 3. Select Land animals. How did the carbon atom get from land plants into the animal? Through them eating the plants 4. Select Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere? It was released into the atmosphere Activity A: Carbon pathways Get the Gizmo ready:  Click Reset. Introduction: Earth can be divided into four systems. The atmosphere is the air above Earth’s surface. The hydrosphere is composed of all of Earth’s water. The geosphere is the rocky, non-living part of Earth. The biosphere consists of all living things, including people. Some scientists use the term “anthroposphere” to describe everything made or modified by humans. Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere? 1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the steps in the path below. Then, label each location with the system it represents. Finally, summarize very briefly how the carbon atom got to that location. Carbon path System How it got there Atmospheric CO2 Atmosphere Atmospheric CO2 comes from volcanoes, burning fossil fuels, and other sources. Exposed rock Oceanic Co2 Shells/corals Geosphere Hydrosphere biosphere Co2 dissolves into rainwater Rainwater breaks down the minerals in the water and releases the C02 They used to dissolved C02 from ocean This study source was downloaded by 100000830772748 from CourseHero.com on 05-06-2022 14:20:10 GMT -05:00 https://www.coursehero.com/file/40590762/CarbonCyclertf/ 2. Create: Click Reset. Use the Gizmo to create a path in which the carbon atom goes from the atmosphere to the hydrosphere, biosphere and geosphere. Describe each transition briefly. Atmosphere Hydrosphere Biosphere Geosphere Atmospheric CO2 Oceanic C02 shells/corals limestone Volcanoes, burning fossil fuels, and other sources. C02 dissolves in cold ocean water Animals use this oceanic C02 as a source of carbon These layers of shells and corals get layered up into limestones [Show More]
