Faults

Faults

• This picture was taken by Coalinga.

• This Fault is known as a Gouge fault because the two layers are separated by a gray layer that looks very ground up.

• consists of broken up and smashed pieces of rock which forms as the two sides of the fault moving against one another.

Weathering processmechanical/physical

Weathering Process-Mechanical

• Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks.

• Exfoliation is the process where the rocks break in sheets along the joints that they have parallel to the earth surface.

• The forces that break rocks down can be numerous, and include such things as pent up energy as the Earth’s crust slowly moves.

Weathering Process-Physical

Physical weathering is the class of processes that causes the disintegration of rocks without chemical change.

• The best example I have seen for physical weathering is sedimentary rocks because you can the dirt brush of the rocks.

• This process takes thousands of years, but it’s a process that has been within the Earth longer than humans.

Mass Wasting

Mass wasting

• This picture was taken in Cambria beach way out in the shore.

• Mass Wasting occurs when the downslope movement of rock and soil pulls down because of gravity.

• As you can also see erosion is also taken place.

sedimentary environments continental, marine, and transitional

Sedimentary Environments

• Continental is dominated by erosion and deposition associated with streams, glacial, and wind.

• Marine is shallow, deep of continental layers

• Transitional is off the shoreline and consist of tidal flats, lagoons, and deltas.

iphone 3G geological field tool

• This electronic device is considered as a geological field because it contains GPS.

• It incorporates accelerometers which can be used to measure the tilt of the device.

• Test over geological structures, the relative speed and accuracy of a conventional compass clinometers and the iphone compass hybrid are demonstrated and campared.

iphone 3G geological field tool

• iphone’s compass is as accurate as the Brunton compass.

• It has different amount of apps so you can use them for different situations

• For example: The ihandy Carpenter app in the premium version serves well as a level and plumb line, making it work for measuring dip angles.
