Questions
1.Is shearing force a Driving or Resisting Force? Is normal force a Driving or Resisting force? Which is which? In your own words, justify your answers. (5 pts)
Shear force is a driving force because its effect is felt parallel to the slope. Normal force is a resisting force because it effects acts perpendicular to the slope (Lemke).
2. In your own words, explain Normal and Resisting Forces using a Boulder on a hillslope as an example. Hint: see you textbook, Chapter 1, for help. (5 pts)
Normal forces or resting forces on a boulder cliff tends to restrict the movement of an object. The angle of the slope is a contributing factor to the movement of a boulder along a hill slope. Additionally, the stability of the slope also affects the movement of an object. In this case, factors such as friction and cohesion determine how fast an object moves (Lemke).
3. Based on your scatter plot and knowledge acquired from your textbook, what is the critical angle, in degrees, that determines if the boulder would move, or not? Why did you choose this angle? (5 pts)
The critical angle for determining whether the boulder would move, or not is 45.840 degrees. At this point, the boulder would assume a stationery motion. The value is arrived by observing the point of intersection between the curves of shear and normal stress.
4. A local business informs you they have a 1 m-thick rock slab with a density of 1000 kg m-3 lying in their backyard that slopes at 25 degrees. Given normal weather conditions and unsaturated soils, will this rock slide and potentially destroy their business? Justify your answer in terms of angle, Driving and Resisting forces. (5 pts)
At 25 degrees, the sheer force on the rock will be 984.807753 while the normal stress will be 173.6481777 (in the opposite direction). This means that the forces propelling the rock slab downwards are greater than the resisting forces. Assuming that the weather conditions remain at normal levels it is highly likely that the rock in question will inflict a considerable damage to the surrounding property.

### Fluvial Geomorphology

... 13 Mar. 2008 FLUVIAL GEOMORPHOLOGY INTRODUCTION Geomorphology is the study of landforms and the processes that shape them. Fluvial Geomorphology is the study of role of rivers in forming the morphology of the earth. In short it is the study of landform evolution related to rivers. Rivers are significant geo morphological agents, they show an amazing diversity of form and behavior and transfer water and sediment from the land surface to the oceans. Highly dynamic in nature, river channels adjust and evolve over timescales that range from hours to tens of thousands of years or more and are found in a wide range of environments. An understanding of fluvial geomorphology has proved its use in channel preservation, environmentally sensitive...

...Geomorphology Geomology is defined as a scientific landform study and all the processes that are responsible in shaping the landscape. The Geomorphologists try to gather knowledge on the manner in which the landscapes look the manner they do. They do this to be able to understand the historical background and dynamics of the land hence predict the changes by a combination of the physical experiments, field observation, and numerical modeling. The earth surface is always modified through combining the processes of the surface that may sculpt the geology and landscape processes that result into subsidence, tectonic and uplift. This paper explores the process of geomorphology. Background Research The processes of the surface are made...

... Introduction The onset of radio-carbon dating has made it possible to precisely determine the age of an organism which formerly lived. Through taking the ratio of carbon-12 to carbon-14 in a particular sample and then benchmarking it to the living organism’s ratio, an individual is able to determine the age. In which case, another important aspect applied is half-life, which is the time taken by half of the sample to decay and is denoted by t1/2. Objective This lab was designed specifically, with a major objective of developing a more comprehensive and hands-on understanding of radiocarbon dating. From this, the specific goals are as follows: Understand half-life and radio-carbon dating Know the difference between radiocarbon ages...

... Introduction The degree of tombstone weathering is figured to rely on various factors given that the some tombstone stayslonger than others do. One of the major the factor that can be measured effectively is the age of the gravestone. Through calibrated relative dating, that involves dating them relative to each other, the age of the tombstones can be arrived at. Other factors that affect weathering degree of a tombstone include type of rock, height, length and thickness. Through exploring these factors, the knowledge about the degree of weathering on tombstones is established. Further, a model for predicting age can be succinctly tested based on weathering degree. As the result of the above concepts, this lab was specifically designed...

... Lab It is crucial to familiarize with various concepts before conducting lab experiments. One of the importantconcepts for this experiment is solubility, which can be defined as the ability of a substance (solute) to dissolve in another (solvent) (Bauer et al. 216). The estimation maximum quantity of a substance that dissolves in a solvent at equilibrium yields solubility (Brown et al. 120). Qualitative analysis is done to identify elements in the sample used for the experiment. For this experiment, qualitative analysis was employed to establish whether or not a precipitate would form upon adding some acids and bases. A flow chart was used to distinguish between cations in the resultant solution. A flow chart refers to a diagrammatic...
