Name ___________S Date ___________Period ___________Earth System WebquestIntroduction:What is the Earth system?A systemis a group of parts that work together. Scientists have started to view Earth as a dynamic system – a combination of different parts that interact, forming a collective whole or entity. The Earth system involves a constant flow of matter through its four different parts. The Earth system is made up of four central components known as the subsystems- the hydrosphere (water), geosphere (rock), atmosphere (air), and biosphere (life). Because a major source of energy for the Earth processes is the sun, it should also be considered part of the Earth system. The two main sources ofenergy for the Earth system are (1) heat from sun and (2) heat flowing out of Earth as it cools.View the following video:ØTask:At the end of this webquest, you will be presented with a photograph. You will have to choose one part of the Earth system and describe how the other parts might be affected if the first part were removed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
