CHAPTER OUTLINE
CHAPTER RESOURCES
•
System: an organized group of parts
that work together to form a whole.
• The Earth system has four major
parts:
1. Atmosphere
2. Hydrosphere
3. Biosphere
4. Geosphere
The atmosphere, hydrosphere,
biosphere, and geosphere work together
to form one large system called Earth.
