Rocky Shore Investigation
Null Hypothesis:
There is no pattern to the distribution of organisms over a rocky
shore.
Variables:
Factors that affect the distribution of organisms over an area of
shoreline are:
· The depth of water which may cover an organism at high tide.
· How resistant an organism in the littoral zone is to dessication.
· How efficiently an organism can conserve water.
· The proximity and availability of nutrition.
Stations
========
I think that stations 1 – 4 are in the sub-littoral zone of the rocky
shore.
Stations 5 – 12 are in the mid-littoral zone.
Stations 13 – 15 are in the splash zone.
I know this through observation on the day, the amount of rock pools
and their depth etc. Consequently the splash zone had no rock pools,
the mid-littoral zone had some, but these were not very deep, the
sub-littoral zone was very close to the sea and was almost all rock
pools with lots of slippery seaweed. My results show that this was
mainly Fucus vesiculosus (Bladdder Wrack).
Analysis of Results:
====================
Animals
-------
There are several clear trends in my results, the clearest of these
being the limpet (Patella vulgata). The majority of limpets were
situated mainly in the mid-littoral zone and splash zone. They had a
peak at station 12 of 31 limpets. Their number slowly built up to this
peak from 1 limpet at station 4 to 33 limpets at station 12. The
limpets also petered out in numbers after station 12, to go 13 to 6 to
0. This tells me that they do not want to be exposed for that long
between tides. However, station 12 still has a ...

...rocky shore. We could have done this by placing two
measuring poles at the required points on the beach and then using a
field level device, such as an Abney level, which consists of a
sighting device and a spirit level. This would have produced two
heights which when subtracted from eachother would have produced
height increase.
We could also have improved the investigation by checking more
thoroughly in the quadrats and by spending more time learning what the
species subtle differences were.
We could have ensured that the groups we took data from for the
averages had spent a decent amount of time on the investigation and
had not rushed it.
There were many aspects of the investigation that could have flawed
the results however overall I think that the practical still reliably
rejected my null hypothesis.

The main idea of Tar Beach, to me, is that your imagination can make anything possible. The young girl uses her imagination to make all she wants her. She first explains how much she loves the George Washington bridge, “The bridge was my most prized possession.” She talks about how her father worked on the bridge and how much that meant to her. The author explains that the girl imagines she can fly and once she flies over something, she claims it to be hers. Throughout the book she claims the union building for her father and the ice cream factory for all of her family to enjoy. She also takes her brother flying with her, “I have told him it’s very easy. All you need is somewhere to go that you can’t get to any other way.” I believe the author

Morro Bay is a beachfront town in San Luis Obispo County, California. It is located along the central coast of California, halfway between San Francisco and Los Angeles. According to the United States Census Bureau (n.d.), the 2010 census reported that Morro Bay had a population of 10,234. Moreover, the 2010 census reported that the total population was composed of 4.4% of persons under 5 years of age, 15.0% of persons under 18 years of age and 23.7% of persons 65 years of age and over. The top three industries in Morro Bay are: “transportation and warehousing; travel, hospitality and tourism; retail and wholesale trade” (Simply Hired n.d.). The companies offering the most jobs in Morro Bay are Gordon Trucking, Cedar Rapids Steel Transport Expedited, and Taco Bell. The per capita income in Morro Bay in 2010 was $31, 899 (Neighborhood Scout, n.d.). Education statistics represent the highest level of education achieved by residents in Morro Bay. In Morro Bay, 8% of residents 18 and over graduated from high school while 31% of residents accomplished a Bachelor’s
There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier beaches.

The very high zone with a deep slope is found in the south-west part of the quadrangle with UTM coordinates from 4623040 meters to 4629000 meters North, and 342760 meters to 349000 meters East. On the other hand, this zone
Within Colorado’s borders lies the home of 104,185 square miles of geology. Within those 104,185 square miles you will find many different types of sedimentary, igneous, and metamorphic rocks. Colorado is split into five physiographic provinces: the Middle Rocky Mountains, the Wyoming Basin, the Colorado Plateau, the Southern Rocky Mountains, and the Great Plains (“Physiographic,” 2013). Inside these provinces are millions of years worth of geological time that tell a story of volcanic eruptions, uplift and erosion, deposition, and metamorphism.
In April 2013, a special memorial playground opened in Sea Bright, NJ. The project, The Sandy Ground Project: Where Angels Play, was organized by New Jersey’s Firefighter’s Mutual Benevolent Association. The playground was one of twenty-six playgrounds being installed in New Jersey, New York, and Connecticut towns honoring the children and teachers killed in the massacre at Sandy Hook Elementary School. Each town that received a playground was a town directly impacted by Superstorm Sandy. This particular playground is dedicated to Anne Marie Murphy, a special education teacher, wife, mother, and hero who passed away during the horrific shooting and is located on Sea Bright Beach which was brutally devastated by Superstorm Sandy.
Costal erosion, especially on barrier islands, is a major concern throughout the world. The issue represents a serious concern for many vulnerable coastlines throughout the coastal regions of the world. This issue must be studied for root causes so it can, if at all possible, be brought under some semblance of control before it is too late. The cost of ignoring this issue would be catastrophic to both communities on the beach and the marine life that depend on the coastal areas for their very survival.
