Due August 10th, 2015 - Just as a living body is a system, the whole Earth is a system. Systems have different parts that work together. Earth scientists use the word sphere to refer to the different parts of Earth’s system: the atmosphere, the hydrosphere, the geosphere, and the biosphere. Like body parts, the Earth’s spheres interact and affect each other. Your mission? Create a video that helps your viewers understand Earth as a system.
Your video must:
* Include this definition of a system: a group of parts that interact
* Explain how Earth is a system
* Clearly and accurately describe the four spheres of Earth's system
* Give at least one example of two or more spheres interacting and affecting each other
* Last no longer than 3 minutes
The four spheres of Earth’s system:
1. Atmosphere: the mixture of gases that make up the air surrounding Earth
2. Hydrosphere: the water that makes up Earth’s ocean, lakes, rivers, and more; also includes the polar ice caps and other ice
3. Geosphere: the solid part of Earth, from its rocky surface to its iron core
4. Biosphere: all the living things on Earth
