The Rise of Earth System Science
What is a model? A representation of an object, a process, or a phenomenon
What does it do? It may show physical features or show how something works

Examples of Models
Model house---lacking water, electricity, smaller
Globe/map---smaller, not always to scaleCarbon cycle*****
