The Relative Importance Of Four Variables As Possible Indicators Of Wake Length

The results shows us that the hypothesis between the river Loughton brook and the erosion shows that it gets wider and deeper due to many reasons such as vertical erosion, lateral erosion, hydraulic action and abrasion of rocks.

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,

A smooth mountain rock surface enhances runoff because it is freeway passage without any chance of retaining any sediments. Other rough rock surfaces alternatively hinder runoff by retaining materials thus less runoff.

The Sarsen Circle at one time had 30 upright sandstones but now only 17 left. They are approximately 13 feet tall and 6.5 feet wide at the bottom and 3 feet towards the top which is thicker and taper. Also adding sarsen lintels to the top that have been shaped to fit the curve of the circle. Their length ranged in about 10 feet and 6 inches. Eventually in sub-phase 3iv, the Bluestone Oval and the Bluestone circle was added that was consisted of igneous rocks including dolerites, rhyolites, and volcanic ash. Finally, in the last sub-phase 3vi, the Slaughter Stone, Avenue, Heel Stone, and Altar Stone were added. The Slaughter Stone is on the northeast side that is the entrance. The Avenue extends north to east from the break in the bank-and-ditch. Along side of this was the Heel Stone which is abut 20 feet tall, including the 4 feet underground. Now the stone leans vertical but it use to stand upright. The Altar stone is about 16 feet long, 3 feet and 6 inches wide, and 1 foot and 9 inches thick. Its placement is embedded in the ground in front of the central and largest trilithon pair. The stone is supposedly suppose to be a Cosheston Bed Sandstone from

There are six different types of water erosion: splash erosion, sheet erosion, rill erosion, gully erosion, valley or stream erosion, and bank erosion. Splash erosion is when raindrops hit soil and small soil particles are displaced. Sheet erosion is when raindrops remove soil in thin layers. During rill erosion, small concentrated flow paths are created. “These paths create a sediment source and delivery system for hillslope erosion. Areas where precipitation rates exceed soil infiltration rates are more prone to this type of erosion. During gully erosion, water flows in narrow channels during or after heavy rains or melting snow. The gullies can erode to considerable depths. Valley or stream erosion is created by water flowing alongside land. It extends downward, deepening a valley, and extending the valley into the hillside. This occurs more frequently

Measure the side length of each block along the grain. When taking a measurement, position the block so the caliper measuring surfaces are touching the end grain faces. Record the measurements to create a data set. Accuracy =.001 in

To determine whether the height at which a marble is dropped affect the size of the crater.

f. Explain how to dry and store different types of stone in a way that will effectively energise them.

Two major laboratories have given two stones that differ markedly in overall quality the same grade. Explain

With volume and mass determined, the density formula (d = m/V) was used to determine the densities of each rock and recorded in g/ml.

The Ellicott City flood was destructive because it was on a high gradient stream. The high gradient stream made it flood faster, and had low stream discharge. Discharge is cross section of stream channel. It was also capable of moving large particles, which is an example of deposition and erosion. In the experiment, the ‘Main Street Ellicott City’ stream was more affected than the Meandering Stream. The Main Street Ellicott City stream was flooded faster, and more houses and cars were destroyed compared to the Meandering

The levee system has disrupted the natural deposits that are left from the overflow of the river.2

“Before us the thick dark current runs. It talks up to us in a murmur become ceaseless and myriad, the yellow surface dimpled monstrously into fading swirls travelling along the surface for an instant, silent, impermanent and profoundly significant, as though just beneath the surface something huge and alive waked for a moment of lazy alertness out of and into light slumber again.” This quote said by Darl describes how the once calm river grew into a more intimidating “alive” being. Nature here uses its element of water to show it no mercy towards the Bundren family, for being impatient. Later in the chapter, the current of the river carries a log which does much damage to the Bundrens including destroying the Bundrens wagon, killing the mule team, scattering Cash’s tools, and almost losing Addie’s coffin. The destruction caused by the river’s current can is comparable to nature’s way of cleansing the the the

Another member of the group chooses a seed crystal and measure the length and width in Millimeters, the 40 Degree group’s crystal was 20 mm by 12mm. (See figure 7)

Furthermore, the measurements from a wooden block and a metal object were taken to calculate their volume and density. In this case, the calculations were more precise but due to other sources of errors, which may be systematic, random or personal, the data was not 100% accurate. There are always certain uncertainties associated with any type of measurement and it is important to know that no measurement will be one hundred percent correct.
