Soil Type Investigation
The aim of the experiment is to establish what types of soil holds the
most water and to see if changing a certain variable such as the ph
value of the water has any effect on how much water each type of soil
will hold.
Background Information
Many factors might affect the absorbency of soil, some affecting only
certain types of soil in particular. For example the obvious
influences such as the amount of soil and the amount of water added to
it will certainly limit how much water the soil can hold and the
amount able to pass through. However, there are also other less
apparent aspects that might also have an effect on the limit of water
different soils can hold. For example the size of the soil particles
might have an influence because if the soil is in large chunks that
leaves gaps in between them then the water may just filter straight
through so little is absorbed by the soil. On the other hand, if the
soil is in a fine grained sand this might trap the water because there
is little space between the particles causing a lot to be absorbed.
Foreign bodies in the soil such as debris, small pieces of litter,
chunks of clay or rocks and even the amount of glass wool used may
also effect the absorbency by either blocking the funnel so that the
outlet is blocked causing the water to be trapped in the filter under
the soil with soil floating on top - though the water is not actually
absorbed, or, if the outlet is not blocked helping the water to drain
easily through the soil so that it hold less.
Another factor which may effect it is the temperature of the water,
according to particle theory, the water particles have more energy and
move faster if the temperature is higher causing more particles from
the surface to escape into the air as they evaporate, thus meaning
that less is held in the soil because it is constantly evaporating at
There are three clear landslides; the southwest landslide is stream-laid sand and gravel from the quaternary that was located on a steep slope resulting in gravity pulling sediments down the steep slope. The northeast landslide appears to be tuff sediments that have fallen upon biotite-quartz diorite rocks. The northwestern landslide is the largest of the landslides. The landslide occurred just south of the creek; erosion must have lowered the creeks elevation creating a steep decline resulting in Bena gravel to fall.

Throughout one’s life, he or she will encounter an opportunity that will likely impact his or her perspective on a given situation. In Waste Land, Vik Muniz embraced the opportunity to travel to Jardim Gramacho in Brazil in hopes of making a difference with the pickers by incorporating the pickers as assistants for the art projects. While at the landfill in Rio de Janeiro, he experiences the life of the pickers which helps him to create the art that will transform the lives of the workers; these experiences allow Muniz to develop as a person (Walker). Vik Muniz’s perspective regarding the landfill and the pickers evolved from expressing pity to embracing the pickers as a group of friends.
A plethora of methods exist to analyse soil in order to determine grave location varying from geophysical techniques to lab analysis. These tests rely on testing soil samples to determine their origins, samples can be compared with others to see how closely they match. Each method has advantages and disadvantages, in forensic contexts results need to be accurate so evidence can hold up in court therefore certain tests will be better suited for the task. The main types of soil are clay, silt, and sand the soils formation and properties are determined by the parent material, climate where it originated, topography, the organisms that inhabit it, and time. The type of soil and particle size determines which techniques are appropriate (Pye & Blott, 2004). The value of soil in relation to determining grave location is essential in preventing a lengthy excavation process, statistical testing is conducted to determine if the samples are a match and if they are how significant.
How does the bare soil surface type affect the amount of runoff? Speculate why this happens.
For Stanley Forman, a photographer of the Herald American news, it was unlike any other day heading to work. News in Boston, which had been going on for months, stated that the protest over a “court-ordered school desecration” was still being held as active. Assigned the task, Forman’s job was to take photos at the City Hall Plaza, where a couple of high school students would demonstrate to the crowd. It seems that Forman wasn’t in such a hurry; however, what came next soon baffled a life as the “agitated” students made their way to a well-dressed black man and attacked as he was walking to City Hall. As the man tried to flee, he found himself about to be assaulted with an American flag by one of the protestors. Forman, who had already snapped over a dozen photos at the scene, caught the image (Sullivan). Although the photo taken was nearly three decades ago, The Soiling of Old Glory caused shock towards the entire nation, which stirred emotions and confusion. It caused a wide range of effects, which drastically changed the lives of the photographer and two main people in the photo. However, because of Boston’s negative view from the public made the photo unnecessary to publish.

The amount of runoff depends on the surface of the Earth. If you have something like pavement you're prone to have more runoff. If you have something like soil, you're prone to have less runoff. Runoff can also be affected by slopes and the ground material.
Water that has changed throughout the hydrologic process travels from the irrigation treatment and enters into the aquifers. First...
Barren Ground by Ellen Glasgow follows the life of Dorinda Oakley, a poor girl living in a desolate town in Virginia. At the beginning of Barren Ground, twenty-year old Dorinda Oakley lives with her family in the town of Broomsedge. She dreams of escaping her farm house for a life in New York when she meets the son of the village doctor, Jason Greylock, and almost instantly, she develops feelings for him. He becomes the “object of her passion” (Bunch). But when she loses him, her life is forever changed. In Ellen Glasgow’s novel Barren Ground, the main character Dorinda Oakley leaves her life of poverty in order to pursue her dream of happiness and in her journey experiences love, loss, and despair.
Located just outside Rio de Janeiro, Jardim Gramacho, Brazil, is the world’s largest garbage landfill. Waste Land is an academy award winning documentary about a modern artist, Vik Muniz, who journeys from his home base in Brooklyn, New York, to his native Brazil, where he visits the landfill. There he photographs four catadores-pickers of recyclable materials. Muniz’s initial objective was to paint portraits of the catadores using garbage, auction off the portraits, and give the money to the catadores, as his way of giving back to the community. However, his collaboration with these inspiring pickers as they recreate photographic images of themselves out of garbage reveals both dignity and despair as the pickers begin to re-imagine their lives.
The tissue would gain in mass and length and will become turgid and sabotaging. If plant tissue has a higher water potential than

When water contains a lot of calcium and magnesium, it is called hard water. Hard water is not suited for all purposes water is normally used for. An acre of corn will give off 15,000 litres (4,000 gallons) of water per day in evaporation. A small drip from a faucet can waste as much as 75 litres of water a day. Of all the water on earth, only 2.5% is fresh water.
