The document discusses the Earth as a system comprised of interacting components or spheres. It defines systems and the key differences between open and closed systems. The Earth system involves the constant exchange of matter and energy between four main spheres - the geosphere, hydrosphere, atmosphere, and biosphere. Each of these spheres affects the others through the transfer of energy and matter across their boundaries, causing the entire Earth system to act as an open, interconnected system.
Earth system science notes
- 2. What is a system? • An organized group of objects/components that interact • The Earth system involves the interaction and transfer of MATTER and ENERGY
- 3. OPEN SYSTEM CLOSED SYSTEM •Energy and matter are •Energy but NOT exchanged with matter is exchanged surroundings. with surroundings •Example: Lake •Example: Closed Michigan….How is Aquarium…How is this energy and matter different from the Lake transferred here? Michigan example?
- 4. HYDROSPHERE ATMOSPHERE EARTH’S SYSTEMS GEOSPHERE BIOSPHERE
- 5. • Read the material provided…Find out what each sphere is and write it in the appropriate place in your notes • FINAL QUESTIONS: Are each of the 4 spheres open or closed systems? Why? Is the entire Earth System open or closed? Why?
- 6. ASSIGNMENT: Foldable for the 4 “spheres” Geosphere-Hydrosphere-Atmosphere-Biosphere • Requirements are as follows… – On the cover-Title, 4 labeled flaps (one for each of the “spheres”) and Decoration/Illustrations – Inside: - On the flipside of each corresponding “sphere” write and illustrate what it is. – Underneath the flaps, describe and show how each of the spheres interacts or affects one of the other spheres. For example, the smoke from a forest fire in the biosphere will end up affecting the atmosphere. Winds will carry ash and smoke to other parts of the world. • Foldable should also be neat, have color, and be the result of effort.
