4. The right portion of Figure 1 describes general characteristics of the ocean bottom in coastal areas that are tectonically passive (not near a plate boundary). The left

The lower shore, or low tide zone, is mostly submerged underwater. The most noticeable difference of this sub-region is the large diversity of different types of seaweeds. Organisms found in this zone are generally less adapted to periods of dryness. The creatures are generally the largest and most complex organisms on the shore as there are more sources of food as marine vegetation flourishes.

Between day 8 and day 14 the Semibalanus start settle lower on the rock and there are none above 4 m. The Semibalanus start to settle mostly between 0-2 m and few Chthamalus are settling in that range. This occurs during neap tides. After day 14 the spring tide occurs and some

Although it supports a number of different organisms, Nudgee Beach lacks many of the fundamentals that make up a healthy and successful ecosystem. The first indicator of this is from the lack of birds present in the area. Although it has been noted for terrestrial bird species – such as kingfishers, pelicans, ibis, egrets, jabiru, stilts and heron – and wading bird species – such as golden plovers, curlews, tattlers and godwits – to have been spotted at Nudgee Beach and surrounding areas in the past; after a day’s worth of extensive observation and research, it was found that the birds observed were limited to magpie, ibis, great knot and eastern curlew species. To intensify this factor, at the time by which this lack of species was recorded, Nudgee Beach was expected to have started seeing tens of thousands of birds arrive for the migratory season [21]. This blatant lack of bird species diversity and quantity may have been due to the lack of small organisms within the ecosystem. The restricted number of small organisms at Nudgee Beach is detrimental to the entire ecosystem as these organisms make up the bottom levels of the food web and provide higher-level organisms with adequate amounts of food to consume. The smaller organisms expected to be observed – including; crustacean, shell, mollusc, lizard, frog, fish, worm, arachnid and insect species – was limited to the infrequent observation of crustacean, shell,

Once these mines were abandoned water slowly began to fill these mines. The water came in contact with all of the leftover minerals, including sulfide, and chemicals began to dissolve into the water. This process of dissolving chemicals into the water essentially turned the water into acid (1). Once the mines finally filled, water began to pour out of the mines into the surrounding area, mostly into a body of water now known as “Tar Creek” (1). This creek then spread the contaminated water throughout the community and into numerous water sources.

The Tidal zones consist of splash zone, high water neap tide, low water neap tide, high water spring tide, low water spring tide, mid tide level and the splash zone and sub littoral zone. All of these tidal zones can be determined by which indicator organisms/animals are living there. For an example the splash zone is the highest of all zones and the organisms that are generally living there are noddiwinkles. If you spot a lot of honeycomb barnacles and blue-grey periwinkle’s then you are most likely in the high water tide zone and water only covers this zone at high tide. White tube worms are indictor organism the mid tide level zone and is covered by water for half of the day. There’s also the low tide zone which is engulfed in water for the majority of the day expect at low tide, you can determine this zone by finding indicator organisms such as sea squirts. The final tidal zone is the sub literal zone and this is always under water the indictor organism’s living here are brown tubeworms and striped girdled chiton.

Fine, sandy beaches often occur in areas with light wave action (California's Ocean Resources, 1995). While a more coarse sand is found with heavy wave action (California's Ocean Resources,

Type of habitat: It inhabits on rocky shores, and is always found in the low intertidal zone.

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment is subjected to extremes of the physical environment such as temperature, desiccation, wave turbulence as well the ecological interactions that commonly occur in biotic communities (e.g. competition, predation). However Rocky intertidal shores are easily accessible by humans and provide an enjoyable opportunity for passive recreation and for science and environmental education as well.

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

The benthic environment has life in, or on, the sand, mud, and rocks. There are two intertidal benthic zones: rocky intertidal and estuary/salt marsh. The rocky intertidal is a rocky mountainous which has been eroded by the wave action and weathering. It is composed of a steep slope. There is an extreme difference between high and low tides. Different from the rocky intertidal is the estuary/salt marsh this is shallow and has less wave action. Coupled with a shallow slope.

These invertebrates include ‘Serpulids, Branchiopods, Sponges, Ascidians, Bivalves, Echinoids and Benthic foraminifers.’ (书) these benthic invertebrates have contributed an important role in cool-water carbonate environment. As the pure carbonate accumulated in a distinctive shallow water, this environment is based on the influence of the assemblage of coralline algae and the beneath invertebrates, which were swept into shoals by the strong tidal

Underground mining accounted for 96% of the coal produced each year when it was done manually, and this was fifty years ago. Most underground mines are located to the east of the Mississippi River; however there are some in Utah and Colorado. More than two-thirds of the coal mined underground is done so using continuous mining machines in the room-pillar method. The continuous miner breaks the coal with tungsten bits on a revolving cylinder, and then conveys it to waiting shuttles which then take the coal to the

Acid mine drainage is most common with hardrock mines where metal ore is bound together with sulfur. The increased acidity created from acid mine drainage has a series of negative effects, depending on the severity of change in the pH level. The acid mine drainage creates inhospitable environments to aquatic life in river systems and former mine sites, with the exception of "extremophile" bacteria (Coil, D., McKittrick, E., and Higman, B., 2010). Acid mine drainage can severely degrade the quality of the water, especially if it's a essential water supply.

The aim of this investigation is to look at the distribution of the ornate limpet, (Cellana Ornata) and the radiate limpet (Cellana Radians) on the rocky shore. We went to the rocky shore of Sirens rocks between Island Bay and Owhiro Bay, on Wellington’s South Coast. We are studying how our chosen organisms affect each other’s distribution patterns. We sampled in the low tide zone, mid tide zone, and high tide zone. The rocky shore we explored was 80 metre long, rocky terrain, bare rock platforms with rock gulley’s.
