The Location of the rocksAll of the rocks that I gathered where located by the highway also known as Intersection 5.

This Area is parallel to the San Joaquin fault where they got eroded from.

The San Joaquin Fault The San Joaquin Hills fault is

blind thrust style fault that extends about 23 miles through coastal Orange County, running from roughly the Seal Beach area to at least Dana Point, and perhaps a bit further south. The fault, whose existence was partly brought to light by UC Irvine geologist Lisa Grant, helped form the San Joaquin Hills and may connect, or be related to, one of more faults just offshore.

Igneous Rocks I had a hard trying to find

what type of rocks I had gathered but the book is very helpful and it said that Igneous rocks are form when molten rock cools down. It also said that it forms crystal over time. Here you cant really see because of the quality of my camera, but it had little crystal that could be seen when the light would hit it.

Sedimentary Rocks I figured this would be a

sedimentary rock because it is form with glassy layers that where left behind by the build up of quartz that cover the region where it’s from.

Metamorphic Rocks This was one of the

toughest one to indentify because it has crystals and I thought it was an igneous rock, but it can be both because Metamorphic rocks come from pre-existing igneous or Sedimentary rocks. This is a quartzite rock.

San Andreas Fault This is a Strike-Slip fault. Strike-slip faults are those where

the relative displacement is parallel to the strike of the fault. Strike-slip fault zones are commonly, but by no means exclusively, steep and can be rather difficult to recognize on cross-sections. However, active strike-slip faults are commonly associated with spectacular tectonic landforms, such as the narrow basin and abrupt range-edge.

Chemical Weathering Chemical weathering

causes the minerals in rocks to decompose. When the minerals are exposed to water, oxygen, acids and bases or carbon dioxide, they may react, resulting in a change in the overall composition of the rock.

Mechanical Weathering is the breakdown of rock

into particles without producing changes in the chemical composition of the minerals in the rock. Ice is the most important agent of mechanical weathering. Water percolates into cracks and fissures within the rock, freezes, and expands.

Mass wasting Mass Wasting includes all

processing by which soil and rock materials fail and are transported down slope predominantly en masse by the direct application of gravitational body stresses.

Here I have a picture of a rock that I found that was moved down by gravity and it is stabled now because of how big and heavy it is, only an earthquake is going to be able and move it.

Erosion Event This is an erosion event

that I found where I found my rocks. By the process of erosion al of the rocks you can see between the hill were eroded by water, wind and gravity.

Geological Use I believe that this Skate

park is a good geological use. It is locate d in Firebaugh.

It’s a geological use because it was built on top of the ground for the use of humans.

Geological Use Here we have another

geological use.

It is a power plant located outside of Firebaugh going towards Madera.
