Dam Or Reservoir Begins To Fill Water
1,212 wordsWater, the life blood of the planet earth. With out water, the earths high variety of life could have never been created. Ever since history has been recorded, man has constructed society around water as a resource. As technology and science increased; civilizations created new ways to store and manage water, this new knowledge came a the production of dams. Many people have already dammed a small stream using sticks and muddy the time they become adults. Humans have used dams since early civili...

Soft Bodied Animals Early Cambrian Rocks Large
1,105 wordsIn Namibia, where the rock record is excellent, Vendian fossils are followed immediately by Cambrian fossils, and they may have overlapped briefly in time. In Siberia, a whole suite of small shelly fossils appears in the rocks as the Cambrian period begins, together with sponges of several different types. Most of the small shells are tiny cones and tubes that we don't understand properly, but at least some of them are complex animals, including the first molluscs. Soon, archaeocyathid sponges w...

Live His Life Free Time
1,288 wordsBill wakes up at about 6: 30 am on a Saturday morning and drinks his cup of coffee as he decides what do with his day off from work. This is not a decision that normally takes a lot of thinking because Bill loves to spend any and all of his free time in the outdoors. As he is sitting at the table he looks out his kitchen window into his backyard. This backyard is unlike the typical American backyard. There are no fences and no neighbors. Well, may one neighbor, but he lives about a mile and a ha...

Puget Sound Heavy Metals
572 wordsIndustry's Toxic Chemical Water Pollution Shipyards, oil refineries, and pulp and paper mills put the health of Puget Sound at risk by not fully meeting their responsibility to control the toxic chemical pollution they generate, according to a detailed report by People For Puget Sound based on the environmental records of 31 facilities.

Supra Glacial Debris Debris Which Occurs Till
1,238 wordsThe characteristics of glacial till reflect the erosional, transportation and depositional history of the constituent sediment. Glacial till is a heterogeneous mixture of rock fragments ranging in size from clay to boulders and is deposited directly from glacial ice without water transport. (Strahler A. H. & Strahler A. N. 1976). Ice sheets deposited in the Pleistocene period may be more than 30 m deep and inevitably the constituents of glacial till will reflect the retreats, advances and statio...

British Isles Sea Levels
1,492 wordster> With Reference to examples discuss the view that coastal erosion is caused by human intervention as a posed to natural processes. For many decades the approach to rapid coastal erosion was to build up sea defences, to try and slow down or even stop the erosion. Initially the attempts were thought a success, however after some years it was realised that the power of the sea and waves could overcome human attempts. Only could protection be a success if huge costs were going to be in...

Book Of Genesis Carbon Dating
1,088 wordsThe debate of the extent and authenticity of the Genesis flood is by no means close to a conclusion. Theories and assumptions of every kind from all directions of biased beliefs have been analyzed, supported and negated. Reviewing publicized scientific and literary texts of the last decade have, however, shined a bit more light on the issue of Moses account in the Pentateuch. Whether biblical or scientific, scholars do not argue the fact that a tremendous natural force of water did splurge into ...

Theory Of Natural Selection Theory Of Natural Darwin
1,108 words... , perhaps because he has more scientific evidence than he had at his disposal on other topics. Darwin uses the example of the neuter worker ants. His reasoning for the neuter gender, on the surface, is much the same as the reasoning for all of the arguments presented to him. He says that he can find neuter insects explicable if such insects had been social, and it had been profitable to the community that a number should have been annually born capable of work, but incapable of procreation [...

Oceanic Crust Ocean Basins
1,875 wordsThe Cordilleran Orogeny The earths lithosphere can be divided into two major structural features: ocean basins and continents. Ocean basins, as we discussed in another essay, are formed at spreading ridges and consumed at subduction zones. The continents are a different story. How did the continents originate, and how have they changed over time? The origin of the earliest continental crust is still relatively obscure, but the evolution of the continents over time is not: the continents have cle...

Prince William Sound Advancement Of Science
1,394 wordsCleaning Up after the Exxon Valdez Was A Mistake Through many hours of research I have determined that the spill cleaning techniques used to clean the Prince William Sound area of Alaska did more harm than leaving the oil where it was. The Alaskan oil spill has become the most studied and managed event of its kind. Although there is not much that can be done about the marine life that came into direct contact with the crude oil, the geologic effects that the oil introduced into the area should h...

Ice Sheets Ice Ages
1,249 wordsContinental Glaciers The Action of Ice on Land As glaciers become extremely large, they eventually reach the lowlands, which is essentially more gentle terrain. As these huge glaciers reach the lowlands, they travel much more slowly, because they no longer have the steep mountain sides to push the ice down faster. Once on the lowlands, the glacier spreads out for they are no longer restricted by valleys, and become known as Ice Sheets. As long more snow falls than ice melts, Ice Sheets will cont...

Rocky Mountains Biological Diversity
1,164 wordsFire Fire And Ecosystems Introduction Fire is an important part of many ecosystems, affecting wildlife populations in various ways, such as by changing habitat, affecting food supply or quality, or by altering interactions of species. Fire suppression has allowed forested areas to achieve a climax state, which provides less forage for wildlife. While terrestrial wildlife is benefited by fire, large fires through the increase in sediment flow negatively impact aquatic ecosystems. Fire is essentia...

Water Quality Water Sources
572 wordsForest Roads And Their Effect On Water Quality Roads are often necessary to perform certain tasks in the forests. When roads are made, they often pose the problem of erosion, and damage to nearby water sources. The two articles I read on this topic were both from the August 1999 issue of the Journal of Forestry. Both discuss the different techniques and methods for trying to limit the amount of silt that contaminates roads due to disturbance. The first article, ? What We Know- and don? t know- a...

Coastal Plain Hudson River
1,539 wordsNew York s Geology The bedrock of the earth is made up of rock bodies that vary in size, shape, orientation, composition, color, and texture. These rocks makeup the bedrock, which is present everywhere. If one were to study a map of the bedrock from a vehicle point of view, they would find that patterns are made by eroded edges and surfaces of rock bodies that crop out of the state. Most rock bodies are originally tubular and horizontal. Deformations of these rock bodies occur over many years du...

Epic Of Gilgamesh Story Of Noah
1,329 wordsFlood stories have been a common thread in many religions across the globe.

Million Years Ago 65 Million Years
1,087 wordsWHERE DID THEY GO? BY JOHN J. HATFIELD EARTH SCIENCE LAB 2234 TERM 2 INTRODUCTION The biggest mystery surrounding the dinosaur is how did they die? For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc. ...

Gold Rush 6 M
805 wordsMining Techniques The way to discover large amounts of gold, was to have the perfect mining technique. One of the earliest techniques was panning and cradling. This method consisted of a pick, a shovel and a washing dish and people either worked by themselves, or in a small group. First of all, panning was a simple method but required a lot of skill. It worked by loading sediment onto the washing device which had a sieve (strain), and moving the pan to and fro until the heavier gold was separate...
