Two weathering processes: MECHANICAL WEATHERINGThe picture above is an example of mechanical weathering. Mechanical weathering is a process wherethere is no chemical change. For example, a rock broken into many pieces is still a rock. There is nochemical change to it. Pressure built up and caused the rock to break in the picture above and it slid upon itself in various areas shown. This picture was taken up a trail in Stanislaus.
CHEMICAL WEATHERINGThis is an example of chemical weathering. Chemical weathering is the process in which thecomposition of the rock changes. In the picture shown above, acid rain has disintegrated the brick wall.
Examples of mass wasting and erosional events: EROSIONThe picture above is an example of erosional events. Erosion is the incorporation and transportation ofmatierals by wind, water, or ice. In the picture, wind and water have created little caves in the rocks.This place is called the Russian Gulch.
GLACIAL EROSIONThis is Half Dome at Yosemite. This is an example of glacial erosion.
MASS WASTINGIm not too sure if this is mass wasting. This picture was taken at Point Loma in San Diego, CA. Itlooks like downhill creeps to me? But nonetheless, it looks pretty awesome.
Sedimentary environments: CONTINENTALI used these dunes in Yuma, AZ as an example of the continental environment. I believe these duneswere made by a process called Aeolian. Aeolian processes involve the wind and its ability to reshape Earths surface.
TRANSITIONALThese are examples of transitional environments, particularly the beach environments. These pictures were taken at Capitola beach and Santa Cruz. The transitional environment pertaining to beaches involves the shoreline and loose particles like sand, gravel, rocks, etc.
MARINEPictured above is a reef. This is an example of the marine sedimentary evironment. It is by far my mostfavorite environment.
Practical Use Of Geology In My Area: MONTECELLO DAM – LAKE BERRYESSAThis is a dam in Napa, CA, about an hour from my house.
SAN MATEO BRIDGEThis is a panaromic view of the San Mateo bridge, which is about 10 minutes away from my house.This bridge is the 25th longest in the world in length and the longest in San Francisco itself. Bedrockforms the base for the bridge and helps support the bridge itself.
FAULTHere is a picture of the Hayward Fault. This was taken on a tour of it; its about ten minutes from myhouse. Cracks in the street are shown and the sidewalk is offset in some places that was caused by afault creep. The Hayward Fault is a strike-slip fault. Grinding causes pressure to build up and land oneach side will shift and cause a shake and crack in the ground.
This is just something extra I thought was interesting. City hall has this swivel-cushion technology ontop of the columns that hold up the building that will help prevent it from collapsing during anearthquake. It has the ability to withstand a 7.5 magnitude earthquake on the Richter scale. Ive neverseen technology like this and I thought Id show you guys!
