 In the picture is a package of Jam floating on top of the water. As you can see most of the area that holds the jam is below the surface, but the top part remains floating. I believe that the jam itself is denser than the water. But because the top of the plastic is solely made out of plastic, it stays floating and does not fully sink. Just going based on whether the jam is floating or not, we would assume that the jam is denser than the water. But because it is still submerged a bit in water, we can conclude that the jam does have some density.

 Right outside of the Baker building, I noticed that there were people doing construction outside a couple days a week. I noticed that a lot of the ground was dug up and left there until the next day of work. The breaking of the dirt does cause erosion.  With the destruction of the ground, there is a loss of vegetation as the land is cleared. The digging starts to loosen the soil, making it easier to produce runoff. Since this is happening near the entrance of the baker, there is not that much ground to soak up the water, which will eventually lead to surface runoff. It could get carried by rainwater and wind if not stabilized. 

Stratigraphy at Spooners Cove What caused the erosion is the movement of the tectonic plates at the San Andreas Fault. They push the horizontal rock upwards, creating these slanted outcroppings. Then, due to weathering, the texture became smooth, and water caused divots and valleys in the rocks.  The layers of the rock seem to be similar. This could hint that they are made out of the same type of rock. But there are many different layers that have different colors. This could also give off that maybe there are different rocks between the layers. These layers were created when sediment was eroded and pushed down by pressure, creating these horizontal layers.  I believe that it took millions of years for these layers to form. Since there are so many individual layers and variations.
