These notes cover the basics of geology, including geological events in the history of Earth, dating techniques for fossils, the physical properties of minerals (such as hardness, luster and streak), types of rocks, organic matter and the basics of dating.

This summary covers essential points on natural resources, including magma differentiation, mining, nutrient absorption by plants, soil composition, tillage, and the tragedy of the commons.

I originally created these notes during my Honors Environmental Science class, but I used them for the event Dynamic Planet in Science Olympiad and they were really helpful. They cover the basics of streams, hydrology, stream discharge/flow, formulas, stream capture/piracy, stream frequency and types of stream frequency, floods and annual exceedance probability, and stream ordering with examples.
