Faults <ul><li>This picture was taken by Coalinga. </li></ul><ul><li>This Fault is known as a Gouge fault because the two layers are separated by a gray layer that looks very ground up. </li></ul><ul><li>consists of broken up and smashed pieces of rock which forms as the two sides of the fault moving against one another. </li></ul>
Weathering Process-Mechanical <ul><li>Mechanical weathering takes place when rocks are broken down without any change in the chemical nature of the rocks. </li></ul><ul><li>Exfoliation is the process where the rocks break in sheets along the joints that they have parallel to the earth surface. </li></ul><ul><li>The forces that break rocks down can be numerous, and include such things as pent up energy as the Earth’s crust slowly moves. </li></ul>
Weathering Process-Physical <ul><li>Physical weathering is the class of processes that causes the disintegration of rocks without chemical change. </li></ul><ul><li>The best example I have seen for physical weathering is sedimentary rocks because you can the dirt brush of the rocks. </li></ul><ul><li>This process takes thousands of years, but it’s a process that has been within the Earth longer than humans. </li></ul>
Mass wasting <ul><li>This picture was taken in Cambria beach way out in the shore. </li></ul><ul><li>Mass Wasting occurs when the downslope movement of rock and soil pulls down because of gravity. </li></ul><ul><li>As you can also see erosion is also taken place. </li></ul>
sedimentary environments continental, marine, and transitional
Sedimentary Environments <ul><li>Continental is dominated by erosion and deposition associated with streams, glacial, and wind. </li></ul><ul><li>Marine is shallow, deep of continental layers </li></ul><ul><li>Transitional is off the shoreline and consist of tidal flats, lagoons, and deltas. </li></ul>
iphone 3G geological field tool <ul><li>This electronic device is considered as a geological field because it contains GPS. </li></ul><ul><li>It incorporates accelerometers which can be used to measure the tilt of the device. </li></ul><ul><li>Test over geological structures, the relative speed and accuracy of a conventional compass clinometers and the iphone compass hybrid are demonstrated and campared. </li></ul>
iphone 3G geological field tool <ul><li>iphone’s compass is as accurate as the Brunton compass. </li></ul><ul><li>It has different amount of apps so you can use them for different situations </li></ul><ul><li>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. </li></ul>
