field lab part 2

This bridge just outside of Parkfield, Ca , straddles the San Andreas Fault. If you look closely, you can see the curve of the guardrail and the angle of the deck. It is evidence of how the fault has caused the bridge to bend. San Andreas fault is called a right-lateral strike-slip fault , which means that the movement of the plates is a side-to-side movement past each other. The Pacific plate is moving north and the North American plate is moving south.

This is a photo of a massive rock , found up in the hills of Coalinga, that has undergone mechanical weathering. As you can see, it has been broken down into two different rocks from a larger rock. Mechanical weathering is accomplished by physical forces that break rock.

Mechanical Weathering

This is a photo of an anticline on the outskirts of Parkfield, Ca. It is a huge rock with traces of the color red. The red is a result of chemical weathering, which alters the composition of a rock.

Chemical Weathering

Mass wasting is the transfer of rocks and soil down slope under the influence of gravity. I took this photo of a huge landslide up in the hills of Parkfield

This is a photo of a soil erosion. Erosion is the general term for the processes that wear down Earth's surfaces. I also took this photo in the hills of Parkfield.

Erosion

Continental Environment

Lake Kaweah is an example of a continental environment. Continental environments are dominated by the erosion and deposition associated with streams. Deposits in lakes come mainly from rivers, but may also be deposited by wind, glacial ice and other processes. These kids are actually swimming in the flooded parking lot of the lake.

Marine environments are divide according to depth; deep and shallow. Shallow marine environments borders all of the world's continents. Deep marine environments include all the floors of the deep ocean.

The Coalinga Oil Field is an example of petroleum geology. In order to find petroleum, companies such as Chevron, need to apply geological science in order to find petroleum. For example, they must study and understand how rocks naturally produce hydrocarbons found beneath the surface of earth that produce petroleum.
