North Stradbroke Island (NSI), also known as Minjerribah to its indigenous people, the Quandamooka people, is the second-largest island in the world, covering an area of 275.2 km2. The island has a wide range of ecosystems including open beaches, frontal dunes, rocky headlands, mangroves, and tidal swamps (Stradbrokeisland.com, 2018). On the island, the sand mining company, Sibelco, are to close their operation on NSI in 1919. This decision has been made through the exploration of advantages and disadvantages of undertaking sand mining on NSI, as well as alternative sources of economic income and planning replacement employment. When making the decision to close Sibelco’s sand mining on the island, it was important to remain mindful to the natives of the island and their ideals, traditions and sacred land. In considering all of these factors, it is most ideal for Sibelco’s sand mining operations on NSI to close.

ecological needs required. Indians who had access to the sea could have very different lives

The climate of the Sunrise Islands is tropical, with warm temperatures all year long. Temperatures stay at 78—87°F throughout the year. Rain is at the lowest in January through March, at 3–4.5 inches, and highest in October, at around 11 inches. The daylight time is the same all year long, at 11.5 – 12.5 hr. per day.

30. Question : Which of the following would you consider not to be a rangland?

These are called barrier islands. Most are long and thin, oriented parallel to the shoreline. These islands have many things in common but also have many different characteristics. They all consist of a sandy beach facing the ocean or Gulf with several other habitat zones including dunes, swales, maritime forests, marshes and tidal flats. The specific natural environments vary from island to island. The bays, estuaries and lagoons found behind the islands are typically rich in marine life. The islands serve to protect these ecologically valuable places. These small land masses also protect human communities on the mainland from the destructive energy of tropical storms and hurricanes. Despite their protective function, barrier islands are very dynamic and always on the move. Their formation depends upon the movement of sand by waves, tides and currents, and these forces continue to act on all barrier islands. Many barrier islands are popular vacation sites. Resort towns have been developed on many of these islands. However, attempts to prevent erosional forces from threatening human-built structures are usually

8. Which of the following is not a major characteristic of a region as defined by geographers?

We need to know if it is mountainous, flat, wooded, urban, rural, near water, near the ocean, heavily populated, whether it has a vulnerable population to the assigned risk, etc. Paint the class a word picture of the area where you live. Do not just tell us where it is.

Barrier Island is a low edge of sand that is parallel to the mainland with a distance of 2 to 19 miles’ off the shoreline, 300 barrier islands border the shore of Cape Cod, Massachusetts, to Padre Island, Texas. The barrier island defends the coast from the full power of storm waves. In the central of the barrier island and the mainland is a peaceful lagoon or a bay. Mainly most of these barrier island are 0.6-3 miles wide and amid from 9-18 miles long. The highest structures example of barrier island are sand dunes with the height of 16-33 feet; however, in some places the dunes can reach the height of 100 feet. Few barrier islands are initiated as spits that were then detached from the inland by upsurge corrosion, rising of sea level resulting

B) The afore mentioned estuary characteristic is more specifically called a lagoon. This means that it is a body of water separated from the ocean by barrier islands and because of this has limited exchange with the ocean through inlets. What makes the Indian River Lagoon so special is the fact that it is North America’s most diverse estuary. There are more than 2,200 different species of animals and 2,100 species of plants living within it.

In just a few short decades, the island has lost over 90 percent of its landmass. Channels cut by companies to assist in oil and logging operations made the island more vulnerable to the effects of flooding and the assault of hurricanes and other storms. The result has been massive subsidence, saltwater intrusion, and land simply disappearing beneath the sea as sea levels rise due to global wrming.

The coral reef surveyors were instructed to find the best sites that they believed had the most living coral and were thought to be least affected by human activities. This would allow Hodgson to determine if human activities were having an appreciable effect on the supposed pristine coral reefs, which were distant from urban centers. The invertebrate survey was undertaken at two depth intervals of 3m and 10m. Four 0.5 m wide by 20 m long belts were placed on the coral reef. Over a period of 3-5 minutes the observers counted the number of invertebrates found on the belts. The coral survey was performed, by placing four 20 m long belts on the coral substrate. At 0.5 m intervals the substrate on which the belts were lying was examined and recorded.
