Percentage of above-surface carbon in the atmosphere =Ībout 1.4% of the above-surface carbon is found in theĬarbon can naturally enter the atmosphere through volcanicĮruptions and impacts from asteroids, and from mid-ocean ridges, naturally Total amount of above-surface carbon = 43,490 billionĪmount of above-surface carbon in the atmosphere = 590 Percentage of above-surface carbon is found in the atmosphere? The least amount of carbon (about 590 billion metric The carbon stored? Where is the least amount of carbon stored?Ībove the surface, most of the carbon (37,000 billion metric tons) is There is about 42,420 times more carbon underneath the surface of theĮarth than there is above the surface of the Earth. Underneath the surface: 1,845,000,000 billion metric tonsĪbove the surface: 43,490 billion metric tons Underneath the surface compare to that above the surface? Round to the correct Lower mantle - about 1,500,000,000 billion metric tons. The majority of carbon on Earth is stored inside the planet in the Based on the Science News article “ Here’s where Earth stores itsĬarbon on Earth stored? How much is stored there? Online access to research information about the carbon cycle and impacts of carbon dioxide in the atmosphereĪ projector for introducing the activity (optional)įor the first part of this activity, have students read the Science News article “ Here’s where Earth stores its carbon” and answer the questions that follow about where Earth’s carbon is found.ġ. Graph paper or computers with graphing software Unbalancing the Carbon Cycle student activity guide The activity questions, calculations and graphing. Temperature anomalies to understand how humans are affecting the carbon cycle.Īpproximate class time: 1 class period to complete Students will graph historical atmospheric carbon dioxide levels and (Readability: 15.1) and then explore the carbon cycle as a class. Procedural overview: Students will answer Understand where carbon is stored in the Earth, how carbon moves throughĮarth’s various spheres and how humans are impacting that carbon flow. ![]() Purpose: After completing this activity, students will better
