The document summarizes Juan Tiscareño's field assignment where he searched for and identified different types of rocks near Firebaugh, CA. He found igneous, sedimentary, and metamorphic rocks. He also observed examples of geological processes like the San Andreas Fault, chemical and mechanical weathering, mass wasting, and erosion. Juan notes two examples of geological uses - a skate park that provides exercise and power plants that generate energy from the geological resources in the area.

4. Igneous Rocks Trying to find an Igneous rock was a really tough thing to do. Trying to distinguish whether it was an igneous rocks was not as complicated though. The book was very helpful and what helped me was that it said that form crystal over time. I don’t know if you can see the crystals in this image but when the light would hit the rock, the crystals were clearly visible.

5. Sedimentary Rock I’m guessing this is a sedimentary rock because it is formed with glassy layers that were left behind by the build up of quartz that cover the area where the rock is originally from.

6. Metamorphic Rock This one was a little confusing for me because at first I thought it was an igneous rock but then I read that it can be both because Metamorphic rocks come from pre-existing igneous or Sedimentary rocks.
