Chalk Out of Eggshells

Remove the sandals to feel the sand between the toes. Each beach on Oahu has a different texture of sand; from a soft powder, to gritty sand, tiny rocks, smoothed glass mixture and small chipped shells. Laniakea beach, also known as “Turtle

Biologists Robin Seeley conducted an experiment in which she gathered periwinkle snail shells on Appledore Island and measures their thickness. The time period in which she has found the snails was before the inhabitation of the European green crab. Eighty years later, the shell thickness of the snails were measured again and recorded. This time, the inhabitation of the european green crab has increased significantly and the thickness of the snail shells has increased. She has concluded that when the crabs arrived on the island, they began to eat the thin shelled snails because their shells were easier to crack.

Solid waste like bags, foam, and other items dumped into the oceans from land or by ships at sea are frequently consumed, with often fatal effects, by marine mammals, fish, and birds that mistake it for food.

• Conch: name give to a number of sea snails, also known by their shell

Long Island is famous for its sandy ocean beaches. Between the barrier beach and the main coast is the Great South Bay. The beaches and dunes have very different characteristics. The sandy beach is the junction of land and ocean. The sandy beach consists of two zones, the swash zone and the drift line. The swash zone is the area of wet sand, caused by the incoming wave. The drift line is formed by the dead seaweed and other aquatic plants. Behind the sandy beach is the primary dune. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. In some cases secondary dunes form. These dunes are behind the primary dune and are therefor protected from the ocean. This provides the stability necessary for plant growth. Many time a maritime forests will form on secondary dunes.

The beauty of California is slowly fading away and as environmentalists would say, “There was once a town in the heart of America where all life seemed to live in harmony with its surrounding” (Carson, 366). According to the findings revealed by research foundations in California, marine life is and has been in great danger as a result of plastic remains that accumulates in the Ocean. In his article Daniel Woods states, “Approximately eighty percent of remains found in Oceans are made of plastic that originates from urban runoffs such as plastic trash carried away from landfills, trucks, as well as garbage containers, marinas, ports and construction trash” (Wood, 20). Furthermore, these results also revealed that marine remains where made up of disposable plastic products that constitute food packaging as well as containers that are ever present and contain precious resources that can be used unsustainably. These issues have affected the state critically and have lead me to research the reasons behind the banning of plastic pollution, their economic impact, harm resulting from plastic pollution, as well as federal concerns on plastic contamination.

The tiny pieces of rocks broken off by weathering are called sediment or alluvium. Erosion is the process of transportation of this sediment which on sea cliffs sediments becomes part of the seafloor and is washed away with the waves. The larger rocks that are broken off by sediment as shown in this picture are called scree or talus; scree builds up at the bottom of cliffs as the rocks tumble down, these piles are called scree slopes or talus piles.

Their shells are fluted, irregular, chalky-white or gray, new growths this often colored purple, and can be distorted to conform to the shape of the object to which the oysters is attached. Oysters are often found in groups attached to one another or to an object such as a rock or a shell. Oysters have uneven valves, which is also known as the shells. The lower shell is cupped and often attached to a hard object. The upper shell is flattened and smaller than the lower shell. Spawning during the hot summer months temporarily reduces the quality of oysters, making them less

Sanibel Island is one of the unique barrier islands of the world, having an east-west orientation when most islands are north-south. With this kind of condition, it’s no wonder that Sanibel is blessed with the pristine white sand beaches littered with many varieties of seashells. So, from Sanibel Island and its resorts, you will definitely enjoy your days collecting the beautiful seashells on the shore. However, it is important to note that in Sanibel Island, collecting live shells is highly prohibited, so just collect the empty ones.

Furthermore, extraction of building materials such as sand affects coral reefs, mangroves, and hinterland forests, leading to erosion and destruction of habitats. Overbuilding and extensive paving of shorelines can result in destruction of habitats and disruption of land-sea connections such as sea-turtle nesting spots. Coral reefs are especially fragile marine ecosystems and are suffering worldwide from reef-based tourism developments. Evidence suggests a variety of impacts to coastline ecosystems result from shoreline development, increased sediments in the water, trampling by tourists and divers, ship groundings, pollution from sewage, overfishing, and fishing with poisons and explosives that destroy coral

There is a type of manta ray that consumes scallops and other shellfish. Sharks eat these rays, and keep them from overeating the scallops. Coastal areas used by fisherman to sustainably catch scallops and shellfish would be gone in a few years (Myers, R., Baum, J., Shepard, T., Powers, S., & Peterson, C. (2007).

It is this soft sand and clay which is easily eroded by the action of waves, as the ocean slowly claims back the region it used to occupy. There are

     Coral animals begin life as free-floating larvae, but settle on the sea floor in sedentary colonies. The term "coral" applies both to these animals and to their skeletons, particularly the skeletons of stone-like corals (Discover 1997).
