Lab Report: Sieve Analysis Of Poorly Graded Hills

Question 1 of 33 3.03/ 3.0303 Points Questions 1 through 5 are based on Lab Exercise #1: Grain Analysis. 1. Bag A contains   A.well-sorted sand.     B.clay.   Correct  C.a moderately sorted mix of sand and silt.

In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

With our observation of the Shawangunk formation, we see a sedimentary rock formation containing a range of grain size. Such sizes range from pebbles (3cm-5cm), fine-grain sand, and medium-grain sand. There is some grading towards the bottom left of the outcrop known as a reverse grading with some small cross beds present (Figure 2). The grading occurs towards a slight part of the outcrop where we see the grading beginning as fine grain sediments and working up to coarser grain. With moderate sorting we see variations of degree of sorting per bed. As the degree of sorting varies as does the sphericity. The sediment bedding is well seen ranging in sizes of +/--20 cm to 40 cm. This outcrop has thick beds as one can see the basic units with cracks in between each (Figure 3). With mostly tabular beds consisting of sub-angular, and sub-rounded sediments, this outcrop also consists of some ventricular beds (Figure 4). When looking at figure 4, we have a small space of a ventricular bed present. This is because the bed comes in, pinches thicker bedding,

We will take 3 measurements of how deep the soil is in 3 different places to get an overall average.

Based on the data from Activities 1 and 2, which is likely the best speed and cesium chloride concentration combination to distinguish different types of soils Why Lab Report The g-force grows exponentially as rpms increase 15000 rpm because it allows for the most separation throughout the sample At 5000 rpm the organic matter, clay, and silt would be at the top while sand and gravel would further down At 15000 rpm each substance would be separated from each other in the order of (top to bottom) organic matter, clay, silt, sand, and finally gravel at the bottom The cesium chloride made the fluid thicker to increase drag 2.5 grams/liter because it formed the most separate layers to work with .5g/L - Organic matter on top the rest on the bottom 2.5g/L organic matter the first 2 layers then clay, silt, sand, and gravel respectively. With a higher cesium chloride levels comes higher drag. With higher drag the materials dont get to spread out as much which causes thinner layers 2.5g/L cesium chloride at 15000 rpm shows the greatest separation of all materials and as such allows for the best distinction between soils.

The mass of salt (.26 grams) was then divided by the total mass of mixture (3 grams) and then multiplied by 100 to get 8.7% salt. The mass of sand was determined by subtracting the 100mL beaker with filter paper and sand (54.57 grams) by the the empty 100mL beaker with filter paper weighing 52.74 grams, to get 1.83 grams of sand. The mass percent of sand was determined by dividing the 1.83 grams of sand by the mass of mixture (3 grams) and multiplying by 100 to get 61%

To calculate the effective diameter of the particles, we use Equation 1 provided below. To determine the effective diameter of the particles, we needed to have the hydrometer readings and temperature for each time taken, as well as using the Coefficient of temperature adjustment table provided in Appendix 3 and the Hydrometer 152H length readings in Appendix 4. To able to determine the Percent Finer for Hydrometer, we use Equation 2 provided below as well as Equation 3 for the Dry Weight of Soil provided below. For Equation 2, we also need the Specific Gravity correction for percent finer table to be able to solve Equation 2. The Specific Gravity correction for percent finer table is provided in Appendix 5. Furthermore, to determine the total

“Drainage patterns, the hilliness of the ground, the range of soils, the nature of the bedrock,

How to take manage of the hill. So it got here to be that standard Prescott did not clearly improve Bunker's Hill, however Breed's Hill as an alternative. How did this appear? One proposed concept is that Colonel William Prescott, due to the fact that fortifying the hill in the midnight, selected the wrong hill. any other principle is that the map the Colonel used become wrong, because many maps in the course of this era had usually misidentified the hills. every other idea, and probable the most sensible, is that Breed's Hill is towards in which the British ships had been located allowing the colonists a higher attacking role than at Bunker Hill. no matter the purpose, the struggle of Bunker Hill without a doubt occurred on Breed's Hill.

Purpose: The purpose of this experiment is to study the physical properties of salt, sand, and iron and use this information to design and carry out a separation of an unknown mixture. The mass percentage composition of the mixture can be calculated from the masses of the recovered components. Materials: Iron Fillings ( Fe) Salt (NaCl) Sand (SiO2) Magnet Balance (Scale)

I then measured out 100ml of soil and then I poured beaker number one through the funnel and let it filter down into beaker number five. I repeated the process with beakers two through four pouring them into beakers six through eight. When completed I let the filtration complete before making my observation. Here are my results.

Hydrosol is a very wet kind of soil and is saturated for the majority of the year, often located where former lake beds occur. Sudosol is more sodic than acidic, it is a Texture Contrast Soil and therefore there is a strong contrast between the surface and the subsoil. This is the most common type of soil in the Mallee region. Vertosols are soils which grow and shrink, causing cracking when the soil dries out. They occur along the creek and river beds as well as the broad plains of the Mallee. Along the coastlines of the Mallee are Calcarosol soils, they, unlike Sudosols and Vertosols, do not have a strong texture contrast throughout its layers. Lastly, two sandy soils have been identified in the Mallee region: Rudosol and Tenosol. Rudosols are very young and undeveloped soils and are widespread in the Big Desert and Sunset Country. Tenosols are also rather undeveloped and occur in the same areas as Rudosols. Tenosols generally have a ‘low water holding capacity and fertility’. Having a vast selection of soils can only mean that a vast selection of produce comes from the area.

Note: Tamp the sand lightly to obtain uniform compaction and to get rid of trapped air. Ensure no air is trapped in all piezometer tubes.

Analysis of representative soil samples will also be undertaken to characterise different soil material, for example, pH, particle size, organic matter, potential contaminants and so on.

The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate.
