2. 1. Fault
Faults are fractures in the crust along which
appreciable displacement has taken place. Most
movements and faults are caused by earthquakes
although most faults are inactive and rather
remnants of past deformation. When movement is
parallel to the dip it is called a dip slip fault.
When the displacement is horizontal and parallel
to the strike the fault is a strike slip fault.

3. 2. Weathering Process

4. Rust
A common example of a weathering process
includes rust. When iron interacts with oxygen
to form the iron oxide hematite, iron is oxidized
and rust is formed. Rust is an example of
chemical weathering.

5. Weathering Process Example
For this field
assignment I chose a
picture of the rusted
wheel to show
another example of
the process of
chemical weathering.

6. Wind
Wind, although not as significant as other
erosional factors, does play a part in erosion.
Usually dryer and scanty vegetation are affected
by wind. For my example the tree that blew
down was already nearly dead and dry.

7. Weathering Process Example
To show an example
of the weathering
process of wind I
chose a picture of a
tree that blew down
recently because of
the

8. 3. Mass Wasting/Erosion
Erosion: the physical removal of material by
mobile agents.
Mass Wasting: the transfer of rock and soil
downslope under the influence of gravity.

9. Erosion: Road
Through erosional
components the road
has deteriorated.
Many erosional
processes as well as
man caused erosion
have caused the road
to break apart.

10. Mass Wasting:
The example I found for mass wasting
was the edge of the irrigation canal.
After water is put through the canal or
it rains the sediment on the edge is
slid downward causing the rocks to
also move. It is not an example of a
big landslide but is an example on a
small scale of mass wasting.

11. Sedimentary
Environments

12. Continental
A continental environment is dominated by
erosion and deposition associated with streams.
For this field assignment the closest thing to me
that resembles a stream is the slough. It is water
that is released from the dam when the rainfall
and snowmelt make too much water. Weather of
continental environments is a big factor of
landscape alteration.

13. Marine
A marine environment is divided according to
depth from the shore to the edge of the
continental shelf. The shallow environments
receive large amounts of sediment from land.
The deeper environments include the floors of
the deep ocean.

14. Transitional
A transitional environment would be the zone
between continental and marine environments.
The ideal picture for an example of a transitional
environment would be a picture of the beach.
The beaches are deposits of sand or gravel. The
work of the waves and currents distributes the
sand. A delta is also a deposit associated with
transitional environments.

15. Practical Geology
One practical use of geology is
the irrigation ditch. I took the
picture of where the water is let
into the ditch. This includes
many agents of geology
including water, sediment,
rocks, and the building of the
ditch and dam.
