All the coasts and
beaches have their own physical and geological characteristic. A rocky or sandy
beach is a good example of a physical coastline. There are beaches that are
made of fish poop which is both physical and geological. An example of a
geological coastline can be cape cod and how it is made from glacial erosion. All
coastlines have their own dynamic feature.
For the past week our
class has been working on a packet on estuaries and coasts. A primary coast is
a coast mostly made from land erosion and volcanic activity. A secondary coast
is a coast that has been made up of water, erosion, and marine life such as
shells and fish poop. We looked at eighteen estuaries and classifications.
On the graph the three different
estuaries go in different directions on the graph. Line a starts low and then
goes up. Line b is very basic and stays near the same depth. Line c almost gets
as deep as line a.
In the packet we got
specific classifications for the twelve estuaries listed. There are coastal
plain estuaries, fjords, bar built estuaries, and tectonic estuaries. For example
San Francisco is a tectonic estuary. That
means the estuaries was made from plate tectonics.
