We use models to represent Earth Systems
WHAT IS A MODEL? “a representation of a real phenomenon that is difficult to observe directly” used to explain and predict the behavior of real objects or systems
Models Physical – 3d models you can touch Graphical – used to show things (maps, charts) Conceptual – verbal or graphical explanation of how a system works or is organized Mathematical – equations that represent the way a system or process works
