When the plant is compressed after it dies, coal is formed. 1. Describe: Using the Gizmo, determine how coal and petroleum (oil) are Describe the steps required to form each fuel from atmospheric CO2.Ĭoal: It goes from the atmosphere to plants in photosynthesis. Question: How does human activity affect the carbon cycle? The burning of fossil fuels, as well as other human activities, increases the amount of carbon dioxide(Co2) in the atmosphere. Introduction: Fossil fuels, such as coal, oil, & natural gas, formed over millions of years from the remains of ancient plants & animals. It can also go from the shells to the limestone to the cement plant to the atmosphere. The sediments & limestone, over time, are broken and packed down to create the lithosphere.ĭ) Explain at least two ways that carbon can get from seashells to theĪns: It can go through the shells to the limestone & also to the lithosphere then to the volcano & to the atmosphere. It can also go from marine plants to marine animals to the sediments & finally to the lithosphere. (The lithosphere is the rigid layer of the Earth, including the crust and part of the)Īns: It can go from the shells to the limestone & also to the lithosphere. It goes into oceanic Co2 by the rainwater breaking it down.Ĭ) Describe two ways that carbon can get from the ocean to the lithosphere. The exposed rock used carbon by dissolving it into the water. Carbon goes into oceanic Co2 by being dissolved by the cold waters. When land animals breathe, they exhale carbon dioxide which is filtered back into the atmosphere.ī) Describe at least two ways that carbon can get from the atmosphere to the hydrosphere.Īns: It can go straight to the hydrosphere or go through the exposed rock to the hydrosphere. When the plants burn in a forest fire, the fumes are carbon dioxide. 4. Explain: Based on the Gizmo, explain how the following transitions might take place:Ī) Describe at least two ways that carbon can get from a land plant to theĪns: It can get there from forest fires and land animals. Path 3: Atmosphere: A – Land Plants: B – Land Animals: B – Atmosphere: A Path 2: Atmosphere: A – Land Plants: B – Coal: B – Power Plant: B – Atmosphere: A Path 1: Atmosphere: A – Oceanic Co2: H – Atmosphere: A Label each location with A for atmosphere, B for biosphere, G for geosphere, or H for: 3. Explore: Use the Gizmo to create three more ( different) carbon paths, each starting and ending in the atmosphere. Then, summarize very briefly how the carbon atom got to that 1. Explore: Use the Gizmo to create a path for carbon (7 steps total) that begins and ends in the atmosphere. Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere? Few scientists use the term “anthroposphere” to describe everything made or modified by humans. The biosphere consists of all living things, including us. The geosphere is the rocky, non-living part of Earth. The hydrosphere is composed of all of Earth’s water. The atmosphere is the air above Earth’s surface. Introduction: Earth can be divided into 4 systems. How did the carbon atom get from land animals back to the atmosphere?Īns: They release carbon dioxide back into the atmosphere through cellular respiration. How did the carbon atom get from land plants into the animal (read the description )?Īns: Land animals consume plants for energy. How did the carbon atom get from the atmosphere to a plant?Īns: Plants use energy from the sun for photosynthesis. Q.2. Click on Land plants and read the description (at the bottom of the simulation). Q.1. From Earth’s atmosphere, where can the carbon atom go next?Īns: Oceanic Co2, land plants, & exposed rock. Q.2. Animals eat plants and produce carbon dioxide and How do animals affect the amount of carbon in Earth’s atmosphere?Īns: They eat plants that process carbon dioxide & when they eat these plants, there are fewer plants that can process the carbon dioxide. Q.1. How do plants on Earth affect the amount of carbon in Earth’s atmosphere?Īns: Plants take in carbon dioxide (co2) and process it into oxygen(o2). (You can find all the answers in green color below) Using the energy of sunlight, plants build molecules of glucose (C6H12O6) & oxygen (O2). In the process of photosynthesis, plants intake carbon dioxide (CO2) from the atmosphere & water (H2O) from the soil. Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Vocabulary: atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis NOTE: All answers are checked twice before publishing them to you. 2 About Gizmo Carbon Cycle Gizmo Answer Key
