- Acid Rain - 1,774 words
Acid Rain What is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. These particles partly dissociate to produce hydrogen ions and bicarbonate ions ...

Acid Rain And North America In the past century, one of the greatest threats to North America's aquatic ecosystem has been the widespread acidification of hundreds of thousands of waterways. Acid rain has effected plant and animal life within aquatic ecosystems, as well as microbiologic activity by affecting the rates of decomposition and the accumulation of organic matter. What causes this poisonous rain, and what can be done to improve North America's water quality and prevent future catastrophes? To answer these questions, we must first examine the cause and formation of acid rain, as well as understand ways to decrease or prevent its formation. Formation of acid rain. Acid deposition, mo ...

Aquaculture Aquaculture is the farming of aquatic organisms in fresh, or salt water. A wide variety of aquatic organisms are produced through aquaculture, including fish, crustaceans, mollusks, algae, and aquatic plants. Unlike capture fisheries, aquaculture requires deliberate human intervention in the organisms' productivity and results in yields that exceed those from the natural environment alone. Stocking water with (juvenile organisms), fertilizing the water, feeding the organisms, and maintaining water quality are common examples of such intervention. Most aquacultural crops are destined for human consumption. However, aquaculture also produces bait fishes, ornamental or aquarium fish ...

Australia Australia The name of Australia comes from the Latin word Australis, which means southern. Since it lies entirely in the southern hemisphere, Australia is most commonly referred to as "down under". Australia, being a country, is also a continent. In land area its the sixth largest for a country and the smallest continent. Australia is a very dry, thinly populated country. Very few coastal areas receive enough rainfall to support a large population. The largest group of Australian people live in two large cities, Sydney and Melbourne. The vast interior is mainly desert or grassland and there are very few settlements. As a whole, the country has a density of six people per square mil ...

... trees. The rain forest contains over 50% of worlds population in plants and animals. It covers roughly 5 billion acres of land. There are 3 layers of trees that can be found there. The first and most top layer is the emergent, which are widely spaced trees 100-120 ft tall with canopies above the general canopy of the forest. The second, middle layer is a closed canopy of 80-foot trees. Here light is available to this layer, but blocks out the light of lower lays. The third layer is a closed canopy of 60-foot trees. This is where little air movement occurs and there is high humidity. Another lower layer is the shrub/sapling layer. In this place of the forest less than 3% of light reaches ...

Catch 22 and Good as Gold - Satire Joseph Heller who is perhaps one of the most famous writers of the 20th century writes on some emotional issues such as war. He does not deal with these issues in the normal fashion instead he criticizes them and the institutions that help carry these things out. Heller in fact goes beyond criticizing he satirizes. Throughout his two major novels Catch-22 and Good as Gold he satirizes almost all of Americas respectful institutions. To truly understand these novels you must recognize that they are satires and why they are. Catch-22 is a satire on World War II. This novel takes place on the small island of Pianosa in the Mediterranean sea late in the war when ...

Corals and Adaptations Coral reefs are among the most diverse and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions ranging from providing food and shelter to fish and invertebrates, to protecting the shore from erosion. Although many corals resemble plants, they are actually members of the animal phylum Cnidaria. Most corals are colonial, which means that each coral is made up of many individual polyps connected by living tissue (the coenosarc). Each polyp has a cup-like shape with a ring of tentacles around a central opening (pharynx) that functions as both mouth and anus. The tentacles are tipped with stin ...

Endangered Species ENDANGERED SPECIES Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals, birds, reptiles, amphibians, and (many people dont consider them) plants. CAUSES OF EXTINCTION Millions of years before humans, extinction of living things was linked to geological and climate, the effects of which were translated into major alternation of the environment. Environmental change is still the primary cause of the extinction of animals, but now the changes are greatly ...

Freshwater Regions Freshwater is defined as having a low salt concentrationusually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There are different types of freshwater regions: ponds and lakes, streams and rivers, and wetlands. The following sections describe the characteristics of these three freshwater zones. Ponds and Lakes These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth, several are remnants from the Pleistocene glaciation. Many ponds are seasonal, lasting just a couple of months (such ...

Hopewell Culture Studied since the discovery of the conspicuous mounds in Ross County Ohio, the Hopewell have been an archaeological enigma to many. The tradition is so named for the owner of the farm, Captain Hopewell, where over thirty mounds were discovered. Earlier studies focused more on the exotic grave goods such as precious metals, freshwater pearls, many of these objects had come from all corners of the continent from the Rocky Mountains to the Gulf of Mexico, and north to the mid-Atlantic coastline (some say Hopewellian influence reached Nova Scotia). Earlier scholars of the Hopewell (1950s through 1960s) were well aware of the influence of the "Interaction Sphere", yet concluded t ...

Hydrothermal Vents Imagine being on the ocean floor. You are in total darkness and in unbearable pressure. You would think that in this freezing environment there is no life, but there is. Eight years ago something was discovered that no one could even imagine. It was a source of life called a hydrothermal vent. A hydrothermal vent is a hot spring found at depths from three to four thousand meters in areas along mid-ocean ridges. Plate movements occurring on the earths crust create vents. They cause the surrounding water to increase to high levels of temperature and also release large quantities of hydrogen sulfide in the form of black smoke. Hydrothermal vents are located in the midnight zo ...

It obtains food and oxygen by means of chemosynthesis; a process in which the organism creates food using chemical nutrients as the energy source instead of sunlight. The bacteria live in cooperation with animals unique to this region, providing them with important nutrients. Animals without backbones are called invertebrates. Lobsters and clams are probably the most numerous and diverse group. Invertebrates in the ocean range from jellyfish to worms and crabs. Vertebrates are animals with backb ...

Ocean Pollution Pollution in our oceans is a serious problem. According to Marie Wild in her article Ocean Pollution, Ocean pollution is one of the major killers of our sea animals.. Most of the waste that is dumped is plastic, which takes hundreds of years to break down (Oceanic Research Foundation [ORF]). Everyday millions of animals are caught in fishing nets and six pack beer rings. It is thought that only fish are affected from getting caught in these. In reality they also kill birds, turtles, dolphins and seals. The animals are slowly strangled or suffocated by the rings as well as cans, fishing line, nets, kite strings and ropes (Wild). Or, as stated be the National Wildlife Federatio ...
