The Agents of Erosion

The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth. Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. Water collecting on the surface of the soil collects as it moves towards tiny rivulets and streams and creates sheet erosion. In streams, water is a very powerful erosional agent. The faster water moves in streams the larger objects it can pick up and transport. This is known as critical erosion velocity. Fine sand can be moved by streams flowing as slowly as three-quarters of a mile per hour. Streams erode their banks in three different ways: 1) the hydraulic action of the water itself moves the sediments, 2) water acts to corrode sediments by removing ions and dissolving them, and 3) particles in the water strike bedrock and erode it. The water of streams can erode in three different places: 1) lateral erosion erodes the sediment on the sides of the stream channel, 2) down cutting erodes the stream bed deeper, and 3) headward erosion erodes the channel upslope. Wind Erosion Erosion by wind is known as aeolian (or eolian) erosion (named after Aeolus, the Greek god of winds) and occurs almost always in deserts. Aeolian erosion of sand in the desert is partially responsible for the formation of sand dunes. The power of the wind erodes rock and sand. Ice Erosion The erosive power of moving ice is actually a bit greater than the power of water but since water is much more common, it is responsible for a greater amount of erosion on the earths surface. Glaciers can perform erosive functions - they pluck and abrade. Plucking takes place by water entering cracks under the glacier, freezing, and breaking off pieces of rock that are then transported by the glacier. Abrasion cuts into the rock under the glacier, scooping rock up like a bulldozer and smoothing and polishing the rock surface. Wave Erosion Waves in oceans and other large bodies of water produce coastal erosion. The power of oceanic waves is awesome, large storm waves can produce 2000 pounds of pressure per square foot. The pure energy of waves along with the chemical content of the water is what erodes the rock of the coastline. Erosion of sand is much easier for the waves and sometimes, theres an annual cycle where sand is removed from a beach during one season, only to be returned by waves in another.

How Of Effectively Use Color On Business Proposals Essay

How to Effectively Use Color in Business Proposals Ian Lauder By Ian Lauder Nov 7, 2011 There is much more to selecting a title page cover design than simply grabbing any design off the shelf. You have to consider the end result you want and the message you are trying to convey. Why are colors so important? Proper use of color will help shape and reinforce your message. First, from a marketing perspective, the objective of a proposal is to sell something: a product, a service, a project, your worthiness for funding, etc. Although we like to believe we are logical in our decision making, the truth is that emotions play a significant factor. Colors help shape the emotional component of your message. The colors a reader sees immediately trigger a subliminal nervous system response and create a specific feeling. Second, colors capture the reader s attention and set up a path for the reader s eye to follow. Our brains are not wired to immediately see and understand the words on a page. Our brains first see colors and shapes; the last thing our brains do is actually make sense of the words. This is why we use eye-catching visuals in our packaging. It s also why the first page of your proposal (the title page cover) should always be eye-catching. You get better results when you capture a reader s attention with color. Third, after you have created a feeling and captured the reader s attention, you want to keep that attention. Proper use of color dramatically increases theShow MoreRelatedInternship Reflection : Summer Internships1402 Words   |  6 Pagesintern during the school year, the summer could be a great option for me.

Meiosis Free Essays

Adam, a man carries millions of biological processes within him. One of these is the production of sperm cells. Everyday his body produces millions of sperm cells through the process of meiosis. We will write a custom essay sample on Meiosis or any similar topic only for you Order Now Adam’s sperm cells are produced from a single parent cell through two stages of cell division. From a single parent cell, four haploid daughter cells are produced which contains half the chromosome of the parent cell. Adam feels nothing of these things going on in her testes. Eve, a woman, also carries millions of biological processes within her. One of these is the production of egg cells in her ovary. She produces a certain number of egg cells through the process of meiosis. Eve feels the presence of egg cells and changes her body temperature in response. Eve’s egg cell also comes from a single parent cell through two stages of cell division. She follows a cycle of egg production in an average of 30 days. Her ovary produces egg cells until the egg cells become ripe. When fertilization does not occur, the egg cells are thrown away by Eve’s body as a form of monthly periodic discharge. Meiosis then produces another set of egg cells for the next cycle. When Adam’s sperm cell and Eve’s egg cell meet, a process known as fertilization occurs. The half chromosome carried by each, combine to form full fertilized egg with a complete chromosomes. Cells from the fertilized egg grow more cells through another form of cell division called mitosis. This growing fertilized egg from the combined chromosome of Adam and Eve then produces a new human being. References: Access Excellence: The National Health Museum Resource Center. Meiosis.

The Goose That Laid the Golden Eggs free essay sample

Avianus and Caxton tell different stories of a goose that lays a golden egg, where other versions have a hen, as in Townsend: A cottager and his wife had a Hen that laid a golden egg every day. They supposed that the Hen must contain a great lump of gold in its inside, and in order to get the gold they killed it. Having done so, they found to their surprise that the Hen differed in no respect from their other hens. The foolish pair, thus hoping to become rich all at once, deprived themselves of the gain of which they were assured day by day. In early tellings, there is sometimes a commentary warning against greed rather than a pithy moral. This is so in Jean de La Fontaines fable of La Poule aux oeufs dor (Fables V. 13), which begins with the sentiment that Greed loses all by striving all to gain and comments at the end that the story can be applied to those who become poor by trying to outreach themselves. We will write a custom essay sample on The Goose That Laid the Golden Eggs or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is only later that the morals most often quoted today began to appear. These are Greed oft o’er reaches itself (Joseph Jacobs, 1894) and Much wants more and loses all (Samuel Croxall, 1722). It is notable also that these are stories told of a goose rather than a hen. The English idiom, sometimes shortened to Killing the golden goose, derives from this fable. It is generally used of a short-sighted action that destroys the profitability of an asset. Caxtons version of the story has the gooses owner demand that it lay two eggs a day; when it replied that it could not, the owner killed it. The same lesson is taught by Ignacy Krasickis fable of The Farmer: A farmer, bent on doubling the profits from his land, Proceeded to set his soil a two-harvest demand. Too intent thus on profit, harm himself he must needs: Instead of corn, he now reaps corn-cockle and weeds. There is another variant on the story, recorded by Syntipas ([[Perry Index 58) and appearing in Roger LEstranges 1692 telling as A Woman and a Fat Hen (Fable 87): A good Woman had a Hen that laid her every day an Egg. Now she fansy’d to her self, that upon a larger Allowance of Corn, this Hen might be brought in time to lay twice a day. She try’d the Experiment; but the Hen grew fat upon’t, and gave quite over laying. His comment on this is that we should set Bounds to our Desires, and content our selves when we are well, for fear of losing what we had. Another of Aesops fables with the moral of wanting more and losing everything is The Dog and the Bone. The majority of illustrations of The Goose that laid the Golden Eggs picture the farmer despairing after discovering that he has killed the goose to no purpose. This was one of several fables applied to political issues by the American illustrator Thomas Nast. In this case his picture of the baffled farmer, advised by a Communistic Statesman, referred to the rail strike of 1877 and appeared in Harpers Weekly for March 16, 1878. Captioned Always killing the goose that lays the golden eggs, the farmer stands for the politically driven union members. His wife and children sorrow in the background.
