PT. 2By: Marissa Solario

San Andreas Fault (Mineral Springs, Ca.)

This part of the San Andreas Fault runs right through an area up in Mineral Springs, just 18 miles west of Coalinga, Ca. A Fault is defined as: “A crack in the earth's crust resulting from the displacement of one side with respect to the other.” This type of fault is known as a “strike slip fault.”

Weathering: the breaking down of rocks, soils and minerals as well as

artificial materials through contact with the Earth's atmosphere, biota and waters.

Mechanical weathering is 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.

Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions.

Mass Wasting

Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, regolith, and rock move downslope under the force of gravity.

These places where mass wasting has taken its toll were taken up on the trail up on the Mineral Springs. Rock slides are one of the bigger issues in this area. (Left) and on the right you can see the way the bushes and such have begun to grow and sag in a downward way.

Sedimentary Environments

Marine: The oceans, seas, bays, estuaries, and other major water bodies, including their surface interface and interaction, with the atmosphere &

with the land. The was taken in Morro Bay, Ca.

Transitional: Environments at or near where the land meets the sea. This includes deltas, beaches, lagoons, salt marshes, barrier islands and tidal flats. This was taken in Ventura, Ca.

Continental: Environments which are present on the continent. This includes rivers, lake, desserts and swamps. This was taken at a swamp in the mountains.
