Week 6 Discussion Question 1
Day 2 [
your response in 200 to 300 words to the following: View the Understanding Faults
animation on this week’s aXcess page.
Describe the different types of faults and discuss at least one similarity and one difference
between a fault and a fold.
If the San Andreas Fault, located in California, is to continue its activity, what does the
future look like for that area? What precautions should be taken?
There are many different types of faults however; there are some significant
differences and similarities between faults and folds. For instance, folds are considered to be
solid rocks that have been deformed; whereas faults are considered to be rock layers that have
been broken-down by the forces of Earth. Folds are the beginning of faults, in which occur when
the rocks are moving and bending. In addition, when flat lying strata from the continental shelf
of Earth collide, it will experience this folding, where faulting is slightly different caused from
stress on the rocks. Such that when these rocks reach a certain point they are then displaced
along the plane of breakage. There are basically three different types of faults to consider the
strike slip, normal, and the reverse fault.
All faults are considered to be some variation of these three. For instance, the strike slip fault can
be represented by the San Andreas fault, where the movement that occurs is a lateral, and in a
sliding motion. The other two types of faults normal, and reverse produce up and down
movement, in addition these types are considered to be the ones that will cause the most damage.
I agree, with your response. I also believe that many of the casualties that occurred
in 1906 from the earthquake were more related to structural causes, and materialistic objects,
rather than from just the earthquake. Indeed, the earthquake itself was the cause for structural
damage and disaster. However, the casualties most likely occurred from falling buildings,
housing, debris, etc, because back then people lacked the knowledge, understanding, and
