They also explore negative feedback loops, such as increased plant growth leading to more carbon absorption.Ħ. Students learn about positive feedback loops, such as the melting of Arctic ice leading to increased absorption of sunlight and further warming. Feedback Loops and Climate Change: The worksheet discusses feedback loops in the carbon cycle and their influence on climate change. They understand the concept of anthropogenic or human-induced climate change.ĥ. Students explore how the burning of fossil fuels, deforestation, and industrial processes contribute to increased carbon dioxide levels in the atmosphere. Impact of Human Activities: The worksheet addresses the impact of human activities on the carbon cycle. Students learn that photosynthesis by plants and algae absorbs carbon dioxide from the atmosphere and converts it into organic matter, while respiration releases carbon dioxide back into the atmosphere.Ĥ. Photosynthesis and Respiration: The worksheet covers the processes of photosynthesis and respiration, which play a crucial role in the carbon cycle. They also explore carbon sinks, such as oceans, plants, and soil.ģ. Students learn about natural sources of carbon, such as volcanic activity and respiration, as well as human-induced sources, including the burning of fossil fuels and deforestation. Carbon Sources and Sinks: The worksheet explores the different sources and sinks of carbon in the carbon cycle. They understand that carbon exists in various forms, such as carbon dioxide (CO2), organic matter, and fossil fuels.Ģ. Students learn that carbon is constantly cycling between the atmosphere, biosphere, hydrosphere, and geosphere. Introduction to the Carbon Cycle: The worksheet begins with an introduction to the carbon cycle. This worksheet aims to provide students with a comprehensive overview of the carbon cycle and its role in shaping our planet's environment.ġ. The "Global Carbon Cycle Worksheet" is an educational resource designed to enhance students' understanding of the global carbon cycle, its significance in the Earth's climate system, and the impact of human activities on this cycle.
