2. Fault San Andreas Fault: Park field, CA. The San Andreas Fault is a strike slip fault, more specifically a right lateral-slip fault. This fault marks the margin line between the Pacific and North American Plates. Movement on a strike strip fault is generally horizontal. This fault is nearly 800 miles long. This is where a part of the fault runs through in Park Field. It is about an hour from Coalinga.
3. Weathering Process Mechanical Weathering: Can be due to temperature pressure. Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks. The rocks are essentially torn apart by physical force, rather than by chemical breakdown. Thermal Stress Weathering: Also due to temperature change. Results from hot during the day, cool at night. Enhanced by moisture.
4. Weathering process Mechanical : (top)This is the side of the creek in Coalinga. It has been weathering because of water that rushes through here in the spring, and how hot the weather is here in Coalinga. Also, there are a lot of rocks here in the Coalinga creek with cracks. Thermal: (bottom)This is a huge rock I found consisting of a lot of smaller rocks. This occurs here in the Coalinga creek because the weather here is very hot, and its cool at night.
5. Mass Wasting/ Erosional Events Evidence of mass wasting: All qualities of materials are set in motion all at once.
6. Mass Wasting/ Erosional Events Evidence of Erosional Events: When materials are removed from earth’s surfaces.
7. Different Sedimentary Environments Continental: Are dominated by the erosion and deposition associated with streams. Marine: Divided according to depth: Shallow or deep marine development. Transitional: Between continental and marine environment.
